I've noticed for the past 2 weeks that one of my white clouds has been very distant from the rest of the school, but most of all, he's very skinny. He tends to stick to the top of the tank, and sometimes he'll be lethargic, and sometimes he'll be swimming around like nothing's wrong. When I fed the fish a few minutes ago, I saw him trying to eat, but he a) either couldn't catch the food... or b) anything he managed to get, he spit back out.
I originally thought that maybe there was a lack of oxygen, because I took out the airstone, but everyone else seems to be doing fine, most of the activity seems to be mid-level and below, except for that one lonely guy. I thought I read somewhere that schooling fish seem to do better in odd numbers, could that be affecting him?? I haven't checked water paramaters since i did a water change this weekend, so I'll do it in a bit.
Could it just be "his time," or should I QT him in the 2.5 gallon, and try to get him to eat. His buddies are voracious eaters, so they left him with nothing after he kept spitting things out.
