What fish can eat the large numbers of Malaysian Trumpet Snails in my tank?

i think any fish you would add that would eat them would also eat your current inhabitants ... i have a shrimp tank with a lot of malaysian trumpet snails and i put a shallow glass bowl with an algae wafer, when the bowl is full of snails i put them into tanks where the fish will eat them (puffers and bettas) ... they are beneficial to your tank and do not increase the bioload to any degree, so unless they are taking over, i would leave them ... and if they are driving you, you can easily sell them, 50 for 10 dollars where i live ... i can easily take 50 out of my shrimp tank with one algae wafer in a bowl ...
