beige round thing with two tentacles

4 of these things crawled off a live rock from LFS. Each is about 2mm in diameter. What do you think these are? thanks!

You have Collonista snails. They breed and consume algae.

+1 for Collonista. Handy little hitchhikers. Very common.

@WheatToast @Isopod80 thank you both! I assume these little guys will die since I am cycling my tank? I do have a few green/yellow sponge on the live rock. Will that sustain them for a bit?

Thanks for the mention! I doubt they will feed on sponge, but they will most certainly survive the cycle (incredibly hardy), feeding on biofilm.

Yeah, they should be fine.
