The Blue Ramshorn Snail (Planorbidae sp.) is a small, round species of snail with a spiral shell. These snails have dark bodies and grey-blue shells. They are good for eating leftover food, algae, and decaying plant matter in aquariums. This species reproduces at a rapid rate, making them a "pest" snail species. Minimum Tank Size: 1 Gallon Maximum Fish Size: .5" Water Temperature: 70F - 78F Ideal pH: 7.0 - 8.0 Water Hardness: 5 - 35 dGH Temperament: Peaceful, bottomfeeder. May be considered a "pest" species due to their ability to reproduce quickly. Unless experienced with fish-in cycling, we always suggest cycling an aquarium BEFORE adding fish. Adding fish to a fresh, un-cycled aquarium can kill them rapidly. We offer free water testing at our physical location, and advice via email or call.
