Hey guys how do you know live rock is healthy? I look at mine and see no life in them (except for the cucumbers which are dead now)... I hear about people finding crabs, mantis shrimp, etc, all sort of critters in their rocks but I'm staring at mine and see no signs of life at all (not that I want a mantis shrimp, but you know, I just want to see something!)... the rock looks so barren & dead. Is this normal? How can you tell if live rock is "good" live rock, or if all the life in it is dead?
