Hi all, just joined and i'm finding this forum extremely helpful. :D here's my prob. just got a new bimac 4 days ago. he's in a 35gal which he shares w/ a serpent star & 1 black & white damsel w/ about 30lbs of live rock & a sandy substrate. sg 1.024, temp 77F, pH 8.25. when i first release him into the tank, he shot across the water and planted himself on a piece of rock. he sat there a min and pulsated colors, then ran inside a cave and i haven't seen him since. i've tried putting chopped fresh shrimp & scallops in the tank, but nothing has made him come back out. last night, out of fear he could have died someplace in the rock, i lifted all of the rocks to look under them, but never found him. i suppose its possible he's inside a hole in one of the rocks and i simply didn't see him. what should i do? any opinions? is there a recommended way to make him come out or at least find him? i don't want to disturb him all the time if he's simply scared, but i need to know if he's still alive! thanks.
