So by the title i'm wondering how you can get rid of vermetid snails, do i just get my fingers and crush them? there's so many on my rocks and a few on my frogspawn but don't seem to be bothering it (not making the polyps retract and heads close etc). is there anything that will eat them? a reef safe chemical that could get rid of them? or do i need to take my aquascape apart and crush them to death.. any input would be helpful.
