My V Tail is in a 180. He light be 5-6". For the past few months he onlybwanted silversides. About 3 days before I transferrd him to a 180 from a 120 he stopped taking food. It might have been 6-7 days now. His stomach is not flat and has a slight bump. Most of what I read involves getting him to eat peas or brine shrimp. He was digging caves yesterday and still normal. Today he seems more lethargic. I'm wondering if I should try ghost shrimp or is more food in hos stomach going to make it worse. What can I do?
