Common Name: Sebae Anemone, Leather Anemone
Scientific Name: Heteractis Crispa
Reef Safe: Yes
Flow: Moderate
Lighting: High
Care Level: Moderate to Difficult
Max Size: Around 30 inches

Appearance:

The sebae anemone has longer tentacles (1.5 to 2.5 inches in length) which is very similar in length to a bubble tip anemone. The tentacle will typically be a brown(ish) color with the tips having a blue to blue/green coloring to them. The below pictures are of my sebae anemone.

Temperament

A sebae anemone has been known to eat smaller fish and invertebrates on occasion.  While the sebae anemone has been known to move, it typically will not do that unless there is something wrong with the water parameters.  For that reason, extreme care should be taken when keeping a sebae anemone in an aquarium with other anemones

Environment

The sebae anemone can get to be a little over 30 inches across which is why I would suggest a tank size of no less than 40 gallons for these anemones (forty gallon breeder is a better minimum tank size). However, a larger tank would make it a lot easier for you to maintain stable water parameters, which is something the sebae anemone truly needs. As with all anemones, they need to be placed in a stable and matured aquarium.  I would only recommend then to hobbyists who are at least somewhat experienced

Sebae anemones are not among the more common anemones available in the hobby these days. In my experience, sebae anemones typically like to attach it’s boot in rocky and sandy spots.  They like moderate flow and high lighting conditions.

Recommended water conditions:

I would refer you to the below article for the typical water conditions that a sebae anemones will do best in.  As a more difficult invertebrate to keep, the sebae anemone will also need both good and very stable water parameters for long term success.

Diet

While sebae anemones can thrive under the correct level of lighting (providing all other requirements are met) they can still benefit from the occasional (or weekly) feeding made up of some meeting foods. You must be careful to offer only high quality foods as anemones (in general) can suffer from bacterial infections when offered poor quality foods. The below link can help you with that as well.

Reproduction

It is not very common for the sebae anemone to reproduce in a home aquarium, even when kept in ideal conditions. 

Fragging

In my opinion, you should not frag anemones as they are invertebrates and not corals.  Although you can find information on line posted by people who claim to have successfully fragged anemones, I would encourage you to read through the below link before considering to attempt fragging an anemone.

A Word of Caution

Handle this invertebrate, and all Anemones, with care. They have the ability to sting with their tentacles.  These stings can cause skin irritations or serious allergic reactions.  Always wear protective rubber gloves when handling anemones

The sebae anemone can also have very sticky tentacles as compared to a lot other anemones.  This can make it a very aggressive eater as it will not let go if a fish (or your hand) were to come in contact with the tentacles.  I would almost be willing to classify these guys as aggressive eaters/predators if it wasn’t not for the fact they typically don’t move.

Clownfish

If you would like clown fish, consider the below list of some the more common clown fish that have been known to readily host in sebae anemones.

Amphiprion Clarkii
Amphiprion Ocellaris, ocellaris clown fish (all color variations)
Amphiprion Bicinctus, or two-band clown
Amphiprion Frenatus, or tomato clown
Amphiprion. Melanopus, or cinnamon clown
