I have had a killin parrot for a while now. When I got him he was relatively small and had no swim bladder issues. Now as he has been getting larger he has buoyancy issues. He cannot swim normally, and spends more time upside down then right side up. He still eats with vigor. Anyone else have this issues? i do not beleive he has any type of infection because he is systemically well and has had this problem for a while now. He has never responded to treatment in the past. Its a shame he is a great looking fish. Just wondering if anyone else has seen this.
