I really hoped I wouldn't have to post in this section so soon but I'm worried about my little guy, Pallas. He was doing fine yesterday afternoon; very alert and swimming. I moved him into my new big tank later on in the night. He seemed to be doing okay for the rest of the evening but when I woke up this morning, he was at the bottom of the tank, barely moving.
He's in his little QT tank right now and is just hanging around at the surface, still not really moving. He's also gone pretty pale and doesn't seem interested in a little pellet of food I left in there for him (he always goes crazy when my hand comes even remotely near the tank surface because he knows it's dinnertime). He's always done great with new tank moves and I haven't done anything different with this one. D: He's my favorite little guy and I'd hate to lose him like this. Any help or advice would really be appreciated.
