Hi, I'm currently setting up a planted 15 gallon crystal red shrimp tank and I'm wondering what snail tank mate would be best for them. I can't have a nerite snail because I treat plant with fenbendazole to tackle hydra which kills nerite snails. In my 10 gallon red cherry shrimp tank I have two long nose snails which do a great job but I would like something abit different and more colourful since they are just dark brown. Ideally I would like a single snail so breeding doesn't happen but would be sufficient to ensure algae levels and waste is controlled. Thanks for your help.
