Last night I received a lot of stuff from a fellow reefer. His tank had 15-20 RBTAs in it, and I was lucky enough to receive one. I put it in the tank last night and when I woke up he went into hiding in a low light, low flow area (He was in a low flow area in the other reefer's tank though). Will he move to an area with more light? He's jammed into a crevice under two rocks (hard to explain)and how do I look and see if he's alright or needs help? Or will I know if he's in trouble by the smell? He said I don't need to feed it. Is this true because a lot of people say you have to feed them? I'll post a pic if he ever moves, he had a great color and was healty.
