My yellow lab has a sucken belly. He is probably 1 to 1 1/2 inches. The rest of the labs at the pet store also had sucken bellys. Is this a deformity or lack of food at the pet store? I had two labs die from what looked like spinal bifida (spelling). These were not from same family.

It sounds like these fish are suffering from parasites. Look for Jungle Parasite Clear and do three consecutive treatments.
