I'm another pro-snail person here. Although, I kinda like the ramshorns and MTS better then the common pond snail, it's still welcome in my tanks.
In my last tank, I had an intial population explosion of those, but over the course of a couple of months or so, ramshorns and MTS became the dominant species. There were still pond snails, but they were a small minority.
They (snails in general) are great for consuming uneaten food, dead plant material, driftwood fungus, some algae, and in the unfortunate event of a death, the fish bodies.
