Hello,
I am re-setting up a 180g tank. I put new substrate and put the live
rock I had back in it. It has been running for 2 months with one fish (Big
Eye) and 24 hermits, 24 snails. I am seeing white fuzzy blobs growing on 4
pieces of live rock. I am not sure if these are sponges or what. I have
tried to take photos and just see the flash.
How can identify these things?
