Mine goes nuts for new life spectrum therm +A he also loves all frozen food. IMO
they need to be fed at least every day. I feed mine directly twice a day to insure all the food gets eaten. He's my favorite fish. Do know he won't use a cave they like to find a little crevis to fold their body into. Mine also loves to be in a barnical. Be sure when you buy him he's healthy. What to look for, bright yellow color, nice thickness in the body, and IMO
most importantly active. Mine will supplement his diet a bit with algae he likes to scrape I off the overflow.
