So, a while back I posted about the fungus AND ich that devastated both of my tanks. Now, I only have Gregory and my otto in one tank and... a new guy named Thor in the other! He's a beautiful VT, but a little odd. He's been in his tank for two weeks, perfectly healthy, but he insists on flaring at EVERYTHING. I walk past, he flares. My boyfriend walks past, he flares. We do a water change, he flares. We drop in food, he flares. The only thing that he doesn't flare at is Gregory, across the way.
The bottom of Thor's tank is bare, and somehow he can see a reflection in the bottom. My boyfriend caught him trying to swim straight down and flare at himself the other day. It was hilarious.
I see this as him just being really territorial, which is fine, because I don't plan on putting anything else in with him. The part that worries me is that he keeps blowing holes in his tail.
Is there anything that you guys can recommend that I do to keep the flaring to a minimum so he won't hurt himself? I know that water changes are the best way to keep him from getting fin rot, but is there anything else I can do to make sure he stays healthy while his tail heals?
