My blue gourami appears to be swimming at a slight angle, almost like he's trying to turn upside-down. Any ideas as to what might be going on with him?
Your gourami probably has a swim bladder disorder. Check to make sure that there are no other problems with him/her. If there are no other visable problems then treat for swim bladder disorder. Get back with us in a few days after treating if your fish is still swimming at an angle.
