Foreign body in red tailed catfish
This young catfish had swallowed objects in the past but regurgitated them. This time it was unable to do so and had been off its food for a few days. A small ulcer had developed near the left pelvic fin and a darkening of the skin was noted at areas where the foreign body caused an internal pressure effect. An X-ray revealed a plastic foreign body in its belly, which was gently removed under anaesthesia. The fish made a rapid recovery over the next few days and is still alive after 12years.
