Well, after 3 days or so I've had a fair bit of trouble with the little guys. Two of them blew up like balloons on Friday, and one started pooping in long white strings. He died after another 24 hours after I medicated him. The other one seems like it's pulled through for now, although its still a little pale and stressed. The other one is fine. Hopefully the survivors are through the worst by now, I think either some sort of internal parasite or bacteria got to them. Not too surprising considering how tiny they were, but it always sucks to lose an awesome fish like an aro, not to mention they weren't cheap. I'll put some new pics up later tonight if I can.
