Me and my fiance have just got a Red Sea Reefer XL 300 and we're trying to put together a stocklist but have hit a problem - she really really doesn't like snails (there's too many in the garden, we're not having any in the house!). After a lot of nagging she has finally agreed to allow some Trochus Snails in, but Nassarius Snails are a definite no (they're too creepy). So what would you use to try to put together a clean up crew, if snails (and probably anything else equally creepy) were off limits?
