I've had absolutely no problem with snails eating plants, only botia's
eating snails =D
I'd agree with that. I've never seen those little snails eat plants.
However, I have seen clown loaches eat plants. They are hell on plants. Don't
get me wrong, I love clown loaches. They are probably my favorite fish. I
have no plans to get rid of mine, despite the holes they leave in my leaves.
But getting clown loaches to get rid of snails can be trading a small problem
for a big one.
Don't worry about those snails. They help keep your tank clean, by eating
leftover food and algae. They won't take over your tank, unless you overfeed.
