tough fish. Make sure it's eating, and keep a watch for disease- they seem prone. Above all, do NOT house them with animals that will be picky. For example, keep away from surgeons, triggers, anything that will nip at their long flowing fins. They are not good swimmers, and once they start getting picked on, they are usually done. I had one for years and fed it bloodworms, shrimp, form 1 and 2. It died quickly after I introduced a purple tang which picked at its fins- and it was dead a day later.
