I just got my first batch of corals. I got a bunch of zoanthid frags
and a colt coral. The zoo's opened up in less than an hour
. As i was going to bed at night i took a lil peek at my tank and i saw my emerald crab very close to one of my zoo's. It was pretty dark so i couldnt tell if he was picking at it or just picking at the rocks under it so i turn on the light and the crab ran away. As for the coral i cant really tell if its damaged or not its still closed up. Should i take the crab out?
