Weird snail in my tank

lissampson · 03/20/2017, 08:19 AM

I have a 75 gallon saltwater tank that I started about 3 months ago. This morning I noticed a strange new and very small snail. Can anyone tell me what snail this is and if it will be a problem?

That looks like a nudibranch---some are quite good and some are pests: wait for an id, but put it into your sump or into a jar if you can.

Looks like a species of aeolid nudibranch. You'll want to dispose of it.

Thanks for the info. You guys were right. I have since found two of their swirly shaped eggs on my zoas. I dip all my corals so I'm bummed these guys got through.
