I noticed quite a bit of bubble algae in my tank and wanted to get an emerald crab as they are supposed to eat it. Some is going away naturally, but there are a few patches that seem untouched. Are emerald crabs totally reef safe? I think I read somewhere that they are known to eat zoas and possibly go after small inverts. I have 2 small-ish cleaner shrimp and getting a mandarin soon. I just want to make sure that it won't wreak havoc on my system.
