Hi everyone. This morning I woke up to a loud splash and found my oscar at the surface of the water swimming sideways. I think it's swim bladder because I just introduced him to a 75 gallon tank and he was still "sulking" at the bottom and he would not have been ready to come out yet as he's not comfortable with the new environment. I don't know how to treat this. please help. I think he may have hit something like a rock and caused it.
