That's sad. My LFS, who knows my tank and i believe is honest and does the right thing, said to keep trying to feed him mysis after I told him he wouldn't eat. I will keep trying.
Any tips on feeding him? He is currently in a ten gallon quarantine with a power head. I turn the power head off and blow a bunch ton of reef frenzy soaked in garlic. I haven't seen him go for it but I leave the food floating/on the floor for about 20 min with the power head off.
