I recently aquired a new Demasoni for my tank, problem is the little guy wont eat anything, I see him picking through rocks from time to time as he appears to possibly be eating algea from them but my tank is pretty clean, Ive tried pellets, flakes, algea discs and nothing seems to peak his interest. Everything is a good quality food with high Spirulina content so you think something would intice him. He shows no signs of being sick, no bloat, is not being bullied, just seems like he has no interest in his food. Any suggestions? Im kind of at a loss of what to do with this little guy.
