I saw a dragonscale king that I really wanted to get, he had such a cool coloring- dark silvery metallic with burgundy spots on his fins. But, he looked very sickly. I was still going to get him, but decided against it, as I was also getting two females, and they'd be in QT, and thus, I'd have to get another tank/heater for him (only have two tank/heater combos).
He didn't seem able to straighten out his back end, nor swim with it much. He made quick darts, occasionally, to the surface to breathe, but otherwise layed, nearly sideways, on the bottom in a curled lump. He was very clamped, slightly bloated, and seemed to just look frightened/stressed in general. Since I wasn't sure what was wrong, I left him. However, now I'm having second thoughts. What could be the possible issue? If I had an idea, I might talk myself into it.
