I have had my Haitian anemone for about a month and a half now, and about a week ago it shrunk and hasn't grown back. It actually started about the same time I added my gold-stripe maroon clown. Could it be that, since these anemones aren't usually hosts, the maroon is irritating it. Also since it is a FOWLR could it be bad water parameters?
And sorry BigLittleHoss don't mean to steal your thread.
