Ramshorn: I consider them a neusence snail. Assassin snails will eat them but never I eradicate them. They will just keep the population in check.
Malaysian Trumpet Snails (MTS): Awesome snails! Good looking and beneficial. They burrow during the day and stir up the substrate which helps out in my planted nano aquariums. They come out at night. Will breed but not over populate your tank. If food is in abundance, they breed, if there is a shortage they will stop breeding. They regulate their population themselves
