Please help identify

Michael Locke · Jun 10, 2018

I have two critters that just popped up on one of my rocks. The first I thought might be aptasia, but was hoping to get clarification. The second looks to be some kind of barnacle. I know the aptasia is bad, but not sure on the barnacles.

Please advise. My tank is very new...about 2 months old.

Michael Locke · Jun 10, 2018

thanks for the id on the majano...i've since looked them up and will be removing him asap. the second picture, i'm sure is some kind of barnacle, pyramid shaped, black and white, little "tongue" sticking out like a string

Vermatid snail?

Possibly a limpet but hard to tell from the pic.

Kamden Uelton · Jun 10, 2018

It's a Limpet Snail.

Are they ok or should I remove them?

Are they ok or should I remove them? I have seen three on the same rock.

Limpets mostly feed on algae, moving slowly and scraping the rock with "teeth" that are among the hardest substances produced by an animal.

I think I've heard of one or two being implicated in coral damage, but I welcome the ones in my tank.
