I was taking out his uneaten food. I noticed he was on the other side of the tank, but when I went to go clean the net I saw this little ball on the sink, luckily he was on the side of the sink and not down the drain. I struggled to pick him, I panicked but got him back into his tank. Problem is when I set him free from the net, he wasn't swimming normal. He was swimming with his head facing the surface. And darted down quick without using his tail, I tried burping him but he kept trying to bite and I dont want to squeeze him will he be ok?
