Brett,
When I first got mine, he was very hard and any invert. But now that hes fat, sassy and fed well, he doesnt touch any of the snails. He does have some aggresion towards some fish, but not the ones you'd expect(same color or shape). I think it would be hit or miss. I got lucky, mine eats everything from pellets to nori and everything inbetween. I like mine and would never get rid of him. I had to rehome for almost a year, but I think they are a great addition. HTH,
Bob
