I just started up my 30 gallon nano about a week ago. And I saw this on one of the live rock I bought. This is the only one I can see. Looks kinda like aiptasia but I am kinda new to this and not sure. These are the best pics I could get. Can you tell me what this is? If its good or bad? And what to do about it? Thanks in advance.View attachment 219510
