My angelicus loach just got sick and I am having difficulty identifying what it is. It has developed several bumps on it's belly that have made the outer skin clear showing some yellow and a little red underneath the skin. It is breathing heavily and also can no longer swim normally. When he tries to swim he swims crookedly and his body tilts to the side or goes upside down. I don't know exactly when it developed as he usually stays inside some hollow rocks inside the tank but I believe it can only have been a couple days. Any help on identifying what it is would be appreciated.
