Hey guys whilst fishing this morning I came across several different species of snails and was wondering if they would be aquarium safe with my corals and fish , Would they just graze away at the algae and keep the sand nice like my turbans and ceriths ? or would they be escape artists ? Would they be likely to bring diseases into my aquarium ? I live on the mid north coast of nsw and the rock pool has fresh water coming over it continuously . I took some photos also , Cheers .
