I just bought a 90 gal rr setup that had been taken down a week ago. The live rock was in a cooler with old tank water over it. One rock had a big leather on it. The guy said he thought it would be ok and to put it back in the tank once I got it set back up. The color doesn't look good, it's all slumped over and pieces of it are breaking off. Should I remove it from the tank or leave it and see if it makes a come back? I'll try to attach a picture. Thanks!
