Trumpet Snails

I have had these snails from day one in a 150 gallon tank with sand substrate and live plants along with Discus,Redtail shark,German Blue rams,Surpea Tetra,Neon tetra, and albino bristle nose and my tank runs great the snails are mostly hidden in the sand till lights out then they swarm the walls and plants till lights on and they retreat back to the sand they work very well on keeping soil free of gasses and algea under control rated 5 stars from me also my snails are breeding so always a fresh set of mini snails to add to another tank if needed
