I have had a 5" BNT in my 220g for about 5 days, 4 blue chromis and a coral beauty are with him. He seems to be doing great, lots of swimming, lots of grazing on live rock and he picks at Nori sheets that I put in the tank. He has no interest in eating meaty foods like brine shimp, Mysis. Will he survive on what he's eating now? Will it take some time before he starts to eat meaty stuff. Any other foods I could try?
