Care
The captive care of this demanding animal should only be undertaken by experienced and dedicated hobbyists that can meet its requirements. This is a frequently exported species, which is, unfortunately very sensitive to the collection and shipping processes. Healthy specimens will be a pale green, grey or beige colour, with long tentacles tipped in blue, purple or pink. All too often, the zooxanthellate Sebae Anemone will have been subject to rough handling or inappropriate conditions in several places along the supply chain, rendering it a bleached bright white colour. These bleached animals are in desperate need of good feedings and appropriate stable conditions so that they can reacquire their vital zooxanthellae. The aquarium itself must be spacious (long, wide and fairly shallow) with stable water conditions. Ideally the tank will have been set up for at least 6 months before the addition of a Sebae Anemone is considered. Good lighting is essential for these creatures, so a shallow position combined with powerful metal halides and the addition of T5s would be most welcome. Vigorous filtration and decent protein skimming are a must, as waste products and fluctuating water conditions will not be tolerated. A roomy refugium can also help to keep conditions stable. This species normally anchors itself to a hard substrate in a favourable position; a healthy, content specimen should not roam about the tank. Moderate to swift current will definitely be appreciated. In the wild, several clownfish species are associated with this anemone (as well as the Domino Damselfish and several species of Periclimenes anemone shrimp). In the confines of the aquarium, the fishkeeper must be aware that some fish and invertebrate species may accidentally swim or move into the anemone's grasp overnight, and will be consumed "“ the chances being greater if swimming space is a bit tight. We must also remember that some species are capable of damaging the anemone (triggers, large puffers etc) so much care should be taken when considering tankmates. Initial placement of the anemone should take into account its preference for good light and current, and be sure to leave a decent sized gap around it to allow for growth, if it is to be kept in the same tank as corals. Kept too close together, the anemone will engage in a stinging war which will cause problems for the corals. May also be seen on sale as the Leathery Sea Anemone.
Feeding
Healthy Sebae Anemones should be fed two or three times per week. Those that are undergoing recovery (i.e. bleached specimens) require feeding much more often. Meaty foods such as silversides, lancefish, smelt, mussel, shrimp should be cut to an appropriate size before feeding (i.e. smaller than the anemone's mouth) and offered to the anemone with a pair of tongs. If clownfish are living in the anemone, they may take pieces of food to it every so often.
Breeding
Reproduction of this species is fairly rare in the home aquarium. Interestingly, these anemones can reproduce by sexual or asexual means.
