Hi everyone, I’m new to saltwater tanks. I was on my way to a fish store the other day and was given a bunch of live rock for free from another saltwater hobbyist. I got excited and put the live rock in my tank and didn’t quarantine any of it. I know a that was a bad mistake. A couple days later I noticed some gsp sprouted out. I have noticed a couple of other things come out of the life rock and I am unsure of what it is and if it is harmful. Any info would help. I currently have a Hippo Tang, 2 ocellaris clownfish a lawnmower blenny, and a mono angelfish in my tank along with some turbo snails and hermit crabs.
