i bought a nice peice of lr the other day that was coverd in black red and yellowish sponges. now i know that as a novice to saltwater that the chance of these staying alive isnt very high but iv got a few questions about them anyways. i have a very large turbo snail he mainly stays to himself on the side of my tank near where i feed him alge strips but today i seen him actually not being lazy and cleaning one of my live rocks. after a few hours he decided to explore the new rock and riped a peice of my black sponge to where its hanging by a thread. my question is if i were to take that peice he broke off and attach it somewhere else will it still grow or is it prity much dead now?
