Well my male zebra danio died today (well he's barely alive, just barely moving his mouth and he can't swim, so he'll probaly die soon.) I had it in my 12 gallon with 3 more zebra danios (females) and a male crowntail betta. Before now I never had any problems, but I found him today on the bottom with half his back fin gone and he was bloody on the sides. I suspect my betta, because he's been kinda aggressive with that particular danio, never the females though. Should I worry about the females? THe betta doesn't mind them, but he'd always go out of his way to take a lunge at the male danio. Also is there a way to euthanize them (If he's not already dead, haven't checked in an hour), I'd rather it not suffer too much, cause it can't move and just is sitting on the bottom of a fishbowl that I filled with water from the aquarium. Or do you think I could somehow save it? (Doubt it) Anyways all help is appreciated. Thanks!
