My Melanuris Wrasse has developed a very distended belly without apparent swimming issues. He continues to eat vigorously. I treated him with antibiotics for 5 days thinking that it may have bloat and/or a swim bladder issue. I saw today that he has stool at his anus that is just showing. So his abdominal swelling would seem to be a bowel obstruction. What now. Has anyone ever caught such a fish and removed the "plug" with tweezers or by messaging the belly. I know this seems extreme, but he will perish if this obstruction is not releaved.
