I have had a onespot foxface for well over 6 months now and have never had any issues with him. Today i got home and noticed he had a massive strand of...well poo.... hanging off of him. It had to be 7 or 8 inches (hes only about 7 inches himself). I also noticed he seemed to be eating sand from the bottom of the aquarium. He seems to have eaten so much sand that his stomach is really bloated looking and he looks like he is going to roll over...litterally. His color is really good and i have not noticed any issues prior to this. Any thoughts?
