something ate my snails

[soonerfan66]

I have a 120 gallon fish only tank with a Coral Beauty , Yellow Tang and many Damsels . I have several Mexican snails which are a few years old . But only now I had a bunch of tiny baby snails show up . But now 3 months later it seems all the baby snails are gone . Which of the fish do you think ate them ?

Any hermit crabs in the tank?

No fish only . It's no big deal just seamed one day I had those little things all over my glass and then one day noticed all gone . I had a few hermit crabs years back but none know .
