The Residents of the 29

I've got a sinking feeling that my angelfish may be bonding. I don't know that I need a mated pair of angels. I think all the other fish would get the crap beaten out of them. It's been too cold and snowy - and we were busy snowboarding - to deal with returning the psycho gourami. He's in the 2.5 tank in the kitchen, awaiting his fate. Meanwhile, as you can see in the video, the cories are so happy. They seem to be doing very well. On a more serious note, the two bettas - Jerkface in particular - seem to be suffering from fin rot. I've been treating him with Bettafix. I'm not sure how to treat Rhaegar, other than to put him in the qt tank. I don't want to subject the salt and pepper cories (habrosas) to any meds. They're sensitive.
