Limpet ID

[asylumdown]

I know that some of these guys can be very bad. So far I almost never see them in the display, but they've definitely taken over my sump. They're even colonizing the inside of my protein skimmer. I don't think they're keyhole limpets, but that's where my knowledge of limpets ends

Ditto...I have the same guys doing the same thing to my sump and overflow. Would love to have an ID

I've had the same for several years with no issues. I don't have an ID unfortunately.

well at least it sounds like they're not harmful to the tank. Though my fingers certainly don't appreciate them when I'm cleaning the skimmer collection cup.

I will let them peacefully be...

Sorry can't ID but found some reading material to put you to sleep by about Limpets
