hello krib, there are various treatments on the market for this problem,BUT,cause most are copper based they can be harmfull to shrimp + similar critters! also certain fish react badly to these type of remedys ie elephant nose,clownloach etc...as for fish that eat snails you couldnt do better than a clown loach, what type of snails are they? if trumpets tell him to catch a load + sell em, ya can get a good price on em
