I've been wanting snails for some time now, but the goldfish in the 90 gal will eat them and the tetras in the 32 gal pick at the horned armor snails, so with the death of my betta, I've decided to turn the 15gal tank into a snail paradise.

Population at the moment is 2 horned armor snails. I would add 2 nerite snails and an apple snail. Thoughts on what other critters would be compatible and happy in a bare or lightly planted 15gal tank?

Food would be veggies I throw in there, algae wafers and items from the other tanks that need a scrub (rocks and anubias plants)
