Description: The Ruby Onion Snail have a truly unique and beautiful shell pattern: dark amber color with small black markings that form encircling stripes. The body of the snail is grey with black stripes. These snails are great algae eaters, and they do not harm the healthy vegetation, therefore Onion Snails are a good choice for planted tanks. They will eat brown, green and hair algae too. The water should be moderately hard and alkaline to allow for healthy shell development, because in softer water, where the calcium concentration will be lower, the snails will be very prone deterioration of the shell. Their aquarium must be covered, as they are excellent escape artists, but it is best to maintain a water line slightly lower than the lid to allow them to move in and out of the water.
