Balloon molly, about 3 months old, roughly 5/8" long, in 20 gal. tank with 20 'littermates" (no other fish) suddenly has caudal fin cocked upwards, at 45-degree angle to body. Eating well, but tends to hang out at rear of tank, and swims vertically to surface for food. Have never seen this in many years of fishkeeping. I spend more time watching this tank than I care to admit, so I don't think it's a congenital abnormality. Disease? Injury?
