Animal guy doesn't know what he's talking about. You're doing a good job with this fish he just doesn't have much color to offer. It's all genetics. The rest of him looks good though and he is filling out nicely IMO. Don't waste your money on chingmix. If you want to try something inexpensive try some "soft and moist with krill sinking pellets" from kensfish.com Keep up the good work.
