I have noticed a bunch of these showing up in my tank lately. They are tiny babies. What should I do, Should I hand remove them?

Keyhole limpet, mine were harmless and ate algae/diatoms but there are many types.

Mine mow algae nothing else will. Great clean up crew

They are fantastic algae eaters. I love having them.

If you're not noticing any problems from them, then I'd probably say to just remove them as desired and offer them to local reefers or your LFS; in some cases, critters like this reproduce to the point where people frustrated by it, but - since they're usually helpful critters- it's not necessarily a bad thing.

To clarify, OP, your critter is a Keyhole Limpet, not a true Limpet - for some info on the difference and on why some people consider keyhole limpets bad (though most are good), see my post in the link below:

Limpets eating corals????

Just bought a few frags of gsp so it could take over the rocks but noticed one of my frags was partially closed and upon further inspection I noticed limpets on it. Are they eating it?
