How strange is it that a fish would have separation anxiety? I think, because wasabi is a very active fish, he just gets bored when no one is around. There is nothing to watch and no one to pay attention to him. Last night I left the mirror up for him and noticed his fins, although still frayed from chewing, look as though they are slowly healing. Of course, we have gone through this before; he lets them slightly grow and then begins chewing on them again. I also noticed this morning that he is working on the beginnings of a bubble nest (which he has never done before). So maybe he's happy having the mirror at night (not so bored or loney)!
I think wasabi is a very beautiful fish. I just wish he would stop chewing on his fins. His body is red with an ever-so-slightly irridesent blue and his fins are half red at the base of his body and the other half of outer fins are cellophane/white. His face (around his eyes and mouth)is also white and his "flare" is red. I've got pictures if you wanna see him!
