Ok well here's my experience so far.
The multibar has only picked on one coral so far, a wellso. He hasn't picked on my clam, sps, acans or chalices so far. I tried mysis, roggers reef food, nori and formula one pellets, nothing did the trick until I tried h2o life spirulina brine mysis and he started eating some and spitting some back out. (I've had him for 3 days). I will also try prawn eggs tomorrow and will continue to try and get him to eat pellets and flakes
Well, a little update on my multibar. He has been taking all the frozen food I've put in the tank. I'm trying to get him to eat pellets and flakes but he doesn't seem interested
