Herbivorous fish in a Planted Tank

[somecallmedaniel16]

Hello all!

So I have just recently planted my 20 gallon high and I was wondering if herbivorous fish are good for a moderately planted tank. If so, what are some good fish for one? (just to note, I have zebra danios, neon tetras, serpae / red minor tetras, and snails) The only herbivorous fish I know of are silver dollars.. Do herbivorous fish help reduce the time you need to spend on pruning?
