Just a few minutes ago I was washing Percy's tank and I put him in a small covered bowl to swim in until his tank was ready. I sat down at my laptop and a few minutes later when I went to check on him, he was flopping on the carpet! I panicked and tossed him into his tank. He's swimming normally, coming up for air, and he's eaten. Then only thing that worries me is possible stress/infection related illnesses. The very tip of his fins look a bit brown, and they weren't before. Is this to be expected with him going through such a harrowing experience? Should I see this go away soon?
