NopeAny wrasses?
No, the rock is from my prior tank so new rock was not introduced to this setup. All i can assume is my large hermit crab or serpent starfish.Hear any clicking that it might be a hitchhiker mantis shrimp?
Was thinking the same but nit sure what. I ordered a turbo snail, checkered snails and small snails.You just added a bunch of new inverts from reef cleaners. Any suspects in that group?
Yes, a few but never seen them do that before.Any Nassarius snails,they are famous for undermining stuff
No, powerheads in the same position for months.How about flow? Any changes or rock work moves that create a settle point near there? I had that going on when I was trying to get current where I wanted. I had random flow on that got too strong. Bottom glass exposed in some areas and big sand mounds in others.
