Clown loaches ADORE snails. That being said, if they've never seen a snail before they probably have no idea how yummy (to them...yuck to me LOL
) they are. Crush a couple against the tank wall with a plastic card (never with your fingers); they'll catch on soon enough and start taking over the job themselves.
My guys started in on the snails the minute they went into my tanks, but there were snails in the tank they came from. Plus, if you have a lot of snails, you may not notice the initial population decline. Look for empty snails shells to let you know if the loaches are chomping on them.
