His left half of his body usually stays down while the right side floats, he can swim fine but is usually found swimming on the floor of the tank.

That is not normal. Separation would be a good idea. What are the water temps? Can you answer some of the questions in the link in my signature?

How long has he been doing this (right-sided floating)? Is he swimming in circles or in the same direction? Is he no longer swimming and just floating? If he has RI, a vet visit would be in his best interest. If his only symptom is that he is lop sided, then that might not be RI, but could be an injury.

I just changed the water about 3 days ago, and i noticed he started doing it. so i read information, and it looked like RI so i seperated him and went to the pet store, gave him a little fish tank water heater and have been dropping in penicilin tablets. hopefully he will make a recovery to whatever he has. i will update and tell you how hes doing. -Daniel
