I noticed that when I get new fish that won't eat right away I normally turn off the PH
's when I feed. The food just kinda hangs around and they eat. But with the fish that I get that won't eat, well it seems that they fair a little better when the food is flting around like it is "live" and they have to catch it. Like in thier natural habitat. Are these "tank bread" or net caught clowns? Maybe if they are "non tank raised" they are not used to being fead like that way. Try a PH
in the QT
when you feed so the Mysis will fly around the tank and see if that will help. Maybe he just needs to chase down his food. This has worked for me in the past.
