Puffer fish is spinning. any ideas???
Basically I have a very large spiny puffer and he all of a sudden will just float around and spining (clockwise only), letting the current take him into the wall. He will come out of it for a few seconds then resumes, it seems as though he has an equilibrium problem. All the other fish are fine.
I have a 600gallon salt water tank, with 2 puffers, one lion fish, undulated trigger, passafor angel, orange dot rabbitfish, blue tang, flame angel, butterfly fish, and a few damsels that survived my lionfish.
