Box fish doing flips and barrel rolls? Sick or just playing?

Chances are it is an internal bacterial infection. Box and Cow Fish are very prone to these... if you catch it early enough, when the fish can still remain underwater or even hold position with out frantic swimming it may survive with a broad spectrum antibiotic treatment in a quarantine tank. Unfortunately usually by the time they are swimming erratically it is too late.
