Do Dwarf Loaches eat snails?

Do dwarf loaches eat snails and I was also wanting to know if I put start out with 3 and then add 2 more at a later time I know that have to have a min of 5. So would that be ok.

 

They do like snails. About the groups of 5, I have 2 groups of 3 and they all seem to be fine. I also have a few more loaches in the tank with them but they are still a group of 3.

My 29 gallon tank. I have been removing snails from my ten gallon daily so I think I may stop for a while so that when I get my loach I can feed them the snails. I will just drop in a few at night when the lights go out to feed them. Will they eat the shell and all or just the insides of the snails?
