Loach recommendation for small planted tank

Hi. I used to have B. striata in my 20g long planted tank (fluorite
substrate), but I moved them to the big tank. Now I have too many snails
in the little tank, so I'm thinking of adding 1-3 small loaches to be
permanent residents. Which species would you recommend? The tank has 4
species of shrimp in it, some ottos and 3 pigmy cories. And thousands of
snails, 3 different species.
Any help would be most appreciated.
