I believe mollies are herbivoresI'm interested in adding some mollies to a 30 gal frag tank. It has a lot of macro and some cotton candy, live rock, a few peppermint shrimp, and some frags. The peppermints are reproducing. I've seen at least one baby shrimp in there. Assuming the mollies would love to snack on those!
They can consume a lot of algae
