i have a clown loach and it loves snails of all kind
if you feed it flakes then you might have a tuff time
if you feed less flakes it would search for snails
but they are night hunters so you might wanna
turn of the lights so the killing spree is not seen on tv
snails always come in plants
i bought a few plants from my lfs's and well some came
with snails when i thought this was a problem
i made a deal with my lmpfs they said if i got a clown loach
from them i was able to return it once it out grew my 48 gal tank
so far its 5 inches and its still eating snails
