Torch Corals

Scientific Name: Euphyilla Glabrescens

Common Name: Torch Coral, Pom-pom coral

Type of Coral: LPS  (Large Polyp Stony Coral)

Lighting: Moderate and Moderate to High

Flow: Moderate

Care Level: Moderate

Temperament: Semi-aggressive to Aggressive

 

Appearance

Torch corals will have a base that consists of an exposed calcified skeleton structure.  At the end of this structure will be individual fleshy heads with long flowing polyps with lighter coloring at the tips.  The heads can be a within a range of colors ranging from pink, green, gold, and brown.  As this coral grows, the heads will split and the skeleton base will branch almost like a tree grows.  These corals can sometimes be mistaken for a Hammer coral or a Frogspawn Coral.  The appearance of the polyps on the heads will allow you to properly identify a torch coral.

Water Conditions

The below link highlights typical water conditions torch corals, as with most LPS, will require.  As this is a moderately difficult coral to keep, you should ensure your dKH, Cal and Mag levels are maintained at all times with minimal nitrate and phosphate levels.  As this coral also has a calcified skeleton, it will consume calcium from your water.  In set-ups with a good amount of LPS corals, it is not uncommon to have to dose dKH and Cal in order to keep the water parameters in line.  With only a few LPS corals, a good water change schedule may be enough to maintain your parameters.  In addition to the article in the below link, this coral can also benefit from maintaining strontium levels if you do not have a good water change routine using a very good quality salt.

General Information

Torch corals, as with all other LPS corals, should be added to mature aquariums. Provided all their requirements are met, they can grow to a colony about the size of your average basket ball within a few short years.  Unless you are planning to move or frag your torch coral, you should give it as much as 30 inches of space in your tank.

The torch coral will release long sweeper / feeder tentacles from its heads to collect food.  This will mostly happen when the tanks lights are off.  These tentacles can also sting and damage or kill other corals within reach, which is how the torch coral will defend itself.  This is what makes the torch more of an aggressive coral as the tentacles can extend as much as 6 to 7 inches beyond the heads.

Although the torch coral will get what it needs from the lighting in your tank, it can also benefit from micro plankton or manual feeding of small pcs of meaty foods placed directly on the mouths at the center of each head.  Although manual feedings are not required, it will help to accelerate growth.

Clownfish have also been known to host in torch corals in aquariums that do not have anemones.  Although this will not harm the clownfish, this can sometimes stress the coral to the point where some of its heads could die off.

As with all corals, the exterior slime coating can be a skin irritant or even highly toxic to humans so please, handle all corals with care.  I would recommend wearing rubber gloves whenever you handle corals

 

Fragging

Torch corals can be fragged with very good success.

Frogspawn Coral

Scientific Name: Euphyilla Paradivisa

Common Name: Frogspawn Coral

Type of Coral: LPS  (Large Polyp Stony Coral)

Lighting: Moderate and Moderate to High

Flow: Moderate and Moderate to High

Care Level: Moderate

Temperament: Semi-aggressive to Aggressive

 

Appearance

Frogspawn corals will have a base that consists of an exposed calcified skeleton structure.  At the end of this structure will be individual fleshy heads with polyps on it. The tips of the polyps will typically be a lighter color when compared to the rest of the polyp.  The heads can be a within a range of colors ranging from green, pink, gold, and brown.  As this coral grows, the heads will split and the skeleton base will branch almost like a tree grows.  The polyps on the heads of this coral will look almost like a mass of frog eggs which is where its common name originated from.  These corals can sometimes be mistaken for a Torch coral or a Hammer Coral.  The appearance of the polyps on the heads will allow you to properly identify a frogspawn coral.

Candy Cane Coral

Scientific Name: Caulastrea Furcata

Common Name: Candy Cane Coral, Bullseye Coral, Trumpet Coral

Type of Coral: LPS (Large Polyp Stony Coral)

Lighting: Moderate and Moderate to High

Flow: Moderate and Moderate to High

Care Level: Moderate

Temperament: Peaceful to Semi-aggressive

 

Appearance

Candy Cane Corals will have a base that consists of an exposed calcified skeleton structure.  At the end of this structure will be individual fleshy heads (polyps) with a small mouth in the center. The heads can be green, blue, or brown like in color.  One of the more common colors is a bright almost neon green.  As this coral grows, the heads will split and the skeleton base will branch almost like a tree grows.

 

Water Conditions

The below link highlights typical water conditions candy cane corals, as with most LPS, will require.  As this is a moderately difficult coral to keep, you should ensure your dKH, Cal and Mag levels are maintained at all times with minimal nitrate and phosphate levels.  As this coral also has a calcified skeleton, it will consume calcium from your water.  In set-ups with a good amount of LPS corals, it is not uncommon to have to dose dKH and Cal in order to keep the water parameters in line.  With only a few LPS corals, a good water change schedule may be enough to maintain your parameters.  In addition to the article in the below link, this coral can also benefit from maintaining strontium levels if you do not have a good water change routine using a very good quality salt.

General Information

Candy cane corals, as with all other LPS corals, should be added to mature aquariums. However, I have found candy cane corals to be among the easier of the LPS corals to keep. Provided all their requirements are met, that can grow to a colony size bigger than your average basket ball within a few short years.  Unless you are planning to move or frag your candy cane coral, you should give it as much as 30 inches of space in your tank.

The candy cane coral will release sweeper / feeder tentacles from its heads to collect food.  This will mostly happen when the tanks lights are off.  These tentacles can also sting and damage or kill other corals within reach, which is how the candy cane coral will defend itself.  What makes the candy cane coral more peaceful than most LPS coral is that its sweeper tentacles are much shorter in comparison only measuring a few inches in length.

Although the candy cane coral will get what it needs from the lighting in your tank, it can also benefit from micro plankton or manual feeding of small pcs of meaty foods placed directly on the mouths at the center of each head.  Although manual feedings are not required, it will help to accelerate growth.

Star Polyps

Scientific Name: Briareum sp (used to be classified as Clavularia viridis)

Common Name: Star Polyps.

Type of Coral: Softie

Lighting: Moderate and Moderate to Low

Flow: Moderate and Moderate to Low

Care Level: Easy

Temperament: Peaceful

 

Appearance

Star Polyps are a smaller coral having a height of about ½ to 1 inch and a head size of about ¼ to ½ inch.  The heads of these corals can completely retract into the base making it look like a think purple coating on your rocks. Green and pink are the more common color to find this coral in.   I have read they can be found in other colors, but I have only seen them in green and pink.

Water Conditions

The below link highlights typical water conditions star polyps will require.  I have had the best luck when they were kept in water with 1 to 2 ppm of nitrate when lighting and flow requirements were met and all other water parameters in line as described in the below link.

https://www.reefaquarium.com/2013/the-basics-of-marine-aquarium-water-parameters/

 

General Information

Star polyps are colonial type corals, meaning they form a colony of many individual polyps all connected together. As they do not have a calcified skeleton structure, they can be more tolerant of swings in the alkalinity, calcium, and magnesium when compared to other corals.  However, they will not be very tolerant to swings in pH, Temp, or salinity which is no different than any other coral or fish..

Star polyps are a very hardy soft coral placing them amount the easier to keep corals and making them an excellent choice as corals for beginners. They have also been known to grow very fast, almost like an invasive coral. These corals can grow on your rocks, on the substrate, and on the glass of your aquarium.  They grow almost like a carpet of small polyps.  Star polyps are also the least aggressive when it comes to defensive abilities. They can quite frequently become damaged and even start losing heads when they fall victim to another coral’s sting or exposed to those toxins.

As with all corals, the exterior slime coating can be a skin irritant or even highly toxic to humans so please, handle all corals with care.  I would recommend wearing rubber glove whenever you handle corals

 

Fragging

Star polyps can be easily fragged with very high success

Horn Coral

Scientific Name: Hydnophora SP
Common Name:, Horn Coral, Hydno Coral, Velvet Horn Coral
Type of Coral: SPS  (Small Polyp Stony Coral)
Lighting: High
Flow: High
Care Level: Moderate to Difficult
Temperament: Semi-aggressive to aggressive

 

Appearance

This is a branching SPS coral, as with many other commonly found SPS corals. It can range in color from a brown or cream color to a bright neon green color.  The surface of the coral will be covered in very short than thick polyps almost giving it an appearance of being covered in “fur”.

Water Conditions

The below link highlights typical water conditions horn corals, as with most SPS, will require.  As this is a moderately difficult to very difficult coral to keep, you should ensure your dKH, Cal and Mag levels are maintained at all times with nitrate and phosphate levels almost undetectable by very good quality test kits. This coral will not tolerate changes in water chemistry very well at all.  As this coral also has a calcified skeleton, it will consume calcium from your water.  In set-ups with a good amount of SPS corals, it is not uncommon to have to dose dKH and Cal in order to keep the water parameters in line.

https://www.reefaquarium.com/2013/the-basics-of-marine-aquarium-water-parameters/

 

General Information

Horn corals as with all other SPS corals, should only be added to mature aquariums. Provided all their requirements are met, they can grow very large to about 12 inches.  Horn corals typically do best when placed on top of rocks, closer to the aquarium lighting and in areas of higher flow.  When provided with the correct conditions, they will grow very fast in an aquarium.

The horn coral can be a somewhat aggressive SPS coral.  It will sting other corals close by. The horn coral would require a distance of around 3 to 4 inches from other corals

Generally speaking, SPS corals can also benefit from the occasional feeding micro-plankton designed for filter feeders

 

Fragging

As with all SPS, they can be fragged with very good success assuming the environmental conditions in the aquarium are suited to SPS corals

Scientific Name: Euphyilla Parancora

Common Name: Hammer Coral

Type of Coral: LPS  (Large Polyp Stony Coral)

Lighting: Moderate and Moderate to High

Flow: Moderate and Moderate to High

Appearance

Hammer corals will have a base that consists of an exposed calcified skeleton structure.  At the end of this structure will be individual fleshy heads with polyps on it. The tips of the polyps will typically be a lighter color as compared with the rest of the polyp. The heads can be a within a range of colors ranging from green, pink gold, and brown As this coral grows, the heads will split and the skeleton base will branch almost like a tree grows.  The polyps on the heads of this coral will look almost like the head of a hammer which is where its common name originated from.  These corals can sometimes be mistaken for a Torch coral or a Frogspawn Coral.  The appearance of the polyps on the heads will allow you to properly identify a hammer coral.

Water Conditions

The below link highlights typical water conditions hammer corals, as with most LPS, will require.  As this is a moderately difficult coral to keep, you should ensure your dKH, Cal and Mag levels are maintained at all times with minimal nitrate and phosphate levels.  As this coral also has a calcified skeleton, it will consume calcium from your water.  In set-ups with a good amount of LPS corals, it is not uncommon to have to dose dKH and Cal in order to keep the water parameters in line.  With only a few LPS corals, a good water change schedule may be enough to maintain your parameters.  In addition to the article in the below link, this coral can also benefit from maintaining strontium levels if you do not have a good water change routine using a very good quality salt.

Plate Corals

Scientific Name: Fungia Repanda

Common Name: Plate Coral, Fungia Plate Coral,

Type of Coral: LPS  (Large Polyp Stony Coral)

Lighting: Moderate

Flow: Low/Moderate to Moderate

Care Level: Moderate

Temperament: Semi-aggressive to Aggressive

 

Appearance

As the name suggests, the plate coral is shape almost like a plate, with a round and somewhat flat body which raises a little in the center where the mouth is.  It is also covered with short little tentacles which can typically range in length from 1/8 to ¾ of an inch.  They can also come in a very wide range of colors from brownish colors to bright yellows, reds, blues and oranges.

Water Conditions

The below link highlights typical water conditions plate corals, as with most LPS, will require.  As this is a moderately difficult coral to keep, you should ensure your dKH, Cal and Mag levels are maintained at all times with minimal nitrate and phosphate levels.  As this coral also has a calcified skeleton, it will consume calcium from your water.  In set-ups with a good amount of LPS corals, it is not uncommon to have to dose dKH and Cal in order to keep the water parameters in line.  With only a few LPS corals, a good water change schedule may be enough to maintain your parameters.

https://www.reefaquarium.com/2013/the-basics-of-marine-aquarium-water-parameters/

 

General Information

Plate corals as with all other LPS corals, should be added to mature aquariums. Provided all their requirements are met, they can grow to about 8 inches. Plate corals typically do best when place in a smooth and sandy substrate on the bottom of the aquarium

This can be a somewhat aggressive LPS coral.  It will release sweeper tentacles that will extend a few inches beyond its base.  They can also over inflate their bodies with water to over twice their normal size allow them to move a little.  These two factors would require a distance of around 5 inches from other corals

These corals can benefit from the occasional feeding of meaty foods, or pellet foods meant for corals.  I would recommend feeding this coral once every week or two for its best long term health. The below link can explain how to feed these corals in more detail

As with all corals, the exterior slime coating can be a skin irritant or even highly toxic to humans so please, handle all corals with care.  I would recommend wearing rubber gloves whenever you handle corals

 

Fragging

Plate corals should not be fragged.

 

Brain Coral

Scientific Name: Trachyphyllia Radiata

Common Name:, Brain Coral, Folded Brain Coral

Type of Coral: LPS  (Large Polyp Stony Coral)

Lighting: Moderate

Flow: Moderate

Care Level: Moderate

Temperament: Semi-aggressive

 

Appearance

Brain will typically have irregular but round like shape with the appearance of folded flesh forming ridges and lower spots in the smooth surfaces in between.  They can have more than one mouth, but these mouths will always be located in the smooth low spots between the folds.  Brain corals will also come in a wide range of colors and can have more than one color on their body. These unique color variations and combinations can make these corals more appealing to many hobbyists.

 

 

Water Conditions

The below link highlights typical water conditions brain corals, as with most LPS, will require.  As this is a moderately difficult coral to keep, you should ensure your dKH, Cal and Mag levels are maintained at all times with minimal nitrate and phosphate levels.  As this coral also has a calcified skeleton, it will consume calcium from your water.  In set-ups with a good amount of LPS corals, it is not uncommon to have to dose dKH and Cal in order to keep the water parameters in line.  With only a few LPS corals, a good water change schedule may be enough to maintain your parameters.

General Information

Brain corals as with all other LPS corals, should be added to mature aquariums. Provided all their requirements are met, they can grow to about 6 inches.  Brain Corals typically do best when place on a smooth and sandy substrate on the bottom of the aquarium.

The brain coral can be a somewhat aggressive LPS coral.  It will release sweeper tentacles that will extend a few inches beyond it’s base.  The can also over inflate their body’s a little with water making them a little larger than normal and in some cases, that can allow them to move by a very small amount   These two factors would require a distance of around 3 to 4 inches from other corals

These corals can also benefit from the occasional feeding of meaty foods, or pellet foods meant for corals.  The below link can explain how to feed these corals in more detail

Long Tentacle Plate Coral

Scientific Name: Heliofungia Actiniformis

Common Name: Long Tentacle Plate Coral, Long Tentacle Fungia Coral, Long tentacle Heliofungia Plate Coral

Type of Coral: LPS  (Large Polyp Stony Coral)

Lighting: Moderate

Flow: Low/Moderate to Moderate

Care Level: Moderate

Temperament: Aggressive

 

Appearance

As the name suggests, the long tentacle plate coral is shaped a lot like a plate, with a round and somewhat flat body which rises a little in the center where the mouth is.  It is also covered with long tentacles (with knob like structures on the tips) which can give it an appearance very similar to many anemones like the magnificent anemone for example.  Long tentacle plate corals are most commonly brownish to olive green in color.

 

Water Conditions

The below link highlights typical water conditions long tentacle plate corals, just as with most LPS, will require.  As this is a moderately difficult coral to keep, you should ensure your dKH, Cal and Mag levels are maintained at all times with minimal nitrate and phosphate levels.  As this coral also has a calcified skeleton, it will consume calcium from your water.  In set-ups with a good amount of LPS corals, it is not uncommon to have to dose dKH and Cal in order to keep the water parameters in line.  With only a few LPS corals, a good water change schedule may be enough to maintain your parameters.

https://www.reefaquarium.com/2013/the-basics-of-marine-aquarium-water-parameters/

 

General Information

Long tentacle plate corals, as with most other LPS corals, should be added to mature aquariums. Provided all their requirements are met, they can grow to about 8 to 10 inches. Long tentacle plate corals typically do best when place on a smooth and sandy substrate on the bottom of the aquarium

This is a very aggressive LPS coral.  It will release long sweeper tentacles that will extend a few inches beyond its base.  They can also over inflate their body’s with water to over twice their normal size, which can allow them to move a little.  These two factors would require a distance of around 5 inches from other corals.

Clownfish have also been known to host in long tentacle plate corals in aquariums that do not have anemones.  Although this will not harm the clownfish, this can sometimes stress the coral to the point where it could become damaged and prone to infections.

These corals can also benefit from the occasional feeding of meaty foods, or pellet food meant for corals.  I would always recommend a weekly (or so) feeding for this coral. The below link can explain how to feed these corals in more detail

Fragging

Plate corals should not be fragged.

Acro Coral

Scientific Name: Acorpora Humilis

Common Name:, Acorpora, Acro Coral, Humilis Acro Coral

Type of Coral: SPS  (Small Polyp Stony Coral)

Lighting: High

Flow: High

Care Level: Very Difficult

Temperament: Peaceful

 

Appearance

The acro coral is a branching SPS coral, as with many other commonly found SPS corals. The shape this branch coral can take will vary between each individual coral from a bush like structure to having fewer and thicker branches. The thicker branches are more common acro to find. It can range in color from a brown or cream color to a bright neon greens along with a few other less commonly found colors.  With over 300 different acro species that are currently documented, it can be a little challenging to properly identify all the different acro corals out there.  Most often, the only noticeable difference can be the coloring and growth patterns.

 

The below arco frag that I bought doubled in size in less than one year

 

Water Conditions

The below link highlights typical water conditions the acro coral, as with most SPS, will require.  As this is a very difficult coral to keep, you should ensure your dKH, Cal and Mag levels are maintained at all times with nitrate and phosphate levels almost undetectable by very good quality test kits.  These SPS will be affected by changes in water chemistry so you will need to ensure your parameters are also very stable. As this coral also has a calcified skeleton, it will consume calcium from your water.  In set-ups with a good amount of SPS corals, it is not uncommon to have to dose dKH and Cal in order to keep the water parameters in line.

https://www.reefaquarium.com/2013/the-basics-of-marine-aquarium-water-parameters/

 

General Information

Acro corals as with all other SPS coral, should only be added to mature aquariums. Provided all their requirements are met, they can grow very large to well over 12 inches. The only thing that will limit their growth is the size of your aquarium.  In the wild they can grow to become several feet, so you can expect to have to trim back (or frag) your acro at some point.  Acro corals typically do best when placed on top of rocks, closer to the aquarium lighting and in areas of higher flow.  When provided with the correct conditions, they will grow very fast in an aquarium.

While the acro coral will not sting any other corals, they can still be harmed by other corals stinging them, it would be a good idea to have your acro placed a distance of around 3 to 4 inches from other corals

Generally speaking, SPS corals can also benefit from the occasional feeding micro-plankton designed for filter feeders

 

Fragging

As with all SPS, they can be fragged with very good success assuming the environmental conditions in the aquarium are suited to SPS corals
