Hi I'm fairly new to the saltwater side of the hobby. I'm starting a quarantine tank (QT) so that I can add more fish to my established 180g FOWLR. I picked up a used 75g setup with live rock (dead rock really since it was dried out for awhile). After getting it up and running I noticed what look like dead/dried out worms and eggs on some of the rock. Are these remnants of bristleworms? If not any clu
e on what they might be?
