| | Re: Tiny species of pest Ramshorn snail
I have assassin snails in most of my tanks, along with ramshorn and Malayan trumpet snails. In my experience, assassin snails reproduce slowly. They slowly increase in numbers until they achieve a predator-prey balance with the other snails. The other species are never completely eliminated, but their population is controlled. Assassin snails will eat fish food if no prey is available, especially if the food has a lot of animal protein in it.
