I have a ten gallon tank where I am raising ramshorn snails for my green spotted puffers. In that 10 gal tank, I want to add other snails for my clown loaches. Are there any species of snails that clown loaches prefer aside from ramshorn snails?
Loaches aren't picky--they'll eat pretty well any snail you put in there, and unlike puffers, there's not concern for them breaking a tooth on a hard shell--they can suck the snail out of the shell.
Mine have just eaten 2 golden apple snails, I bought them thinking they looked nice and forgot clown loaches eat snails, next thing I know I've got two lovly hollow shells at the bottom of my tank, oooops, lesson learnt I suppose.
