I've got a 55gal FOWLR
which until recently has been inhabited by a young volitan and a steadily declining number of damsels. Four days ago I added a One Spot Foxface and he seemed to adjust well until he suddenly became ill and died this evening. I'm going out of town for the holidays and will wait to replace him until I'm back buy I'm looking for clues as to why he suddenly went under. Please let me in on any ideas you've got.
P.S. I've been a long time follower of the forum, but this is my first post. Nice to meet you all.
