I have a 3" prkipne puffer that was going great just the other day but suddenly he's not lookin so good. His eyes are wide open and his mouth is also wide open all the time (his smile is gone). It also seems like he's having a herd time swimming - he's bumping into everything. This all started after I added 3 new fish to my tank..........Any ideas on how to help him????
