I just got a call that my brother inlaws new puffer fish has something about .5 inch long sticking out “its back side” its all white but at the base looks bludy read. I told him it sounds like it may be a part of its insides that came out last time it pooed but I truly have no idea on just what and how can he help it back in with out pushing it with his fingers the puffer is only about 2 inches in total length. Anybody have any ideas to help him out that I can pass along.
