are 2 turbo snails for a 13.5g to much?

I have a 13.5g fluval tank and picked up 2 turbo snails, by recommendation of my LFS when I had a diatom bloom. They do a great job however they kind of tear up my Zoa's at times. Would this be to much for a nano tank?

I don't think so, but just make sure that everything is secure or else they'll be knocking things over constantly.

Depending on their size you may want to supplement their diet with some nori. A 13g tank won't provide enough micro or macro algae for their diet.
