Hey everyone I just put a new small yellow belly blue tang in my 100 gal soon to be sps tank. Hes the 6th fish in there with 4 cardinals and a flasher wrasse. Hes been in the tank with lights off darting around and a occasional twitch. Hes been in there about 3 hours now. Is this typical behavior? Also towards the top of the tank. I guess time will tell. Any thoughts?
