Limpet growing on snail?

[Dkmoo]

Is that a limpet growing on my cerith? I thought they generally move like a snail but this guy has never moved from the cerith shell. Guess it has a personal chauffer carrying him to all the food places...

Also is it reef safe? AFAIK its the only limpet in the tank.

Yep! Definitely looks like a limpet. As far as I know, they pose no threats to reef tanks

Yeah I have one on a big turbo snail it's doubled in size over the year it's pretty funny to watch
