I am not having a whole lot of luck with my Kuhli's eating the snails but I know when I had my Yo-yos they devoured them and when the snails were gone they would eat the food that any carnivore would eat but I got them Sinking Carnivore wafers for treats they loved. They also loved the Omega One Sinking Wafers that contained spirulina even though they were not technically carnivore food they were based with Salmon and other fish meal and they loved them. The only loaches that I know do not eat snails at all are the Chain loaches or Dwarf Loaches (same fish different supplier) as they are just too small to fight with the snails successfully. They do not get to more than 2" or so in size. The Yo-yos can get to 5 to 6 inches and do better in groups of 2 or 3 but will live with just one.

Another fish that I saw recently that does a fair job is the Angelicus loach but unfortunately neither of the ones that I ordered lived long enough to do the full job as they are kind of fragile little guys and we have had power issues lately. They are smaller than the Yo-yos however if space is an issue and one to a tank they do quite well where a lot of the loaches need to be in a group.
