Sebaes are a more difficult species. I haven't been able to keep any alive at all. When choosing one, the darker the better. Alot of the white ones are bleached out and dying, which I found out the hard way.
The sebae anemone is H. crispa, there are no alternate names. They come in many variations. Sebaes require bright light and will often move to a high spot in your tank. They really don't need to be fed, but an occasional snack won't hurt of course.
