5 Ramshorn Snails - VERY HEALTHY and PEST FREE! Assorted colors, but mostly Pink. We have a very healthy, pest-free, happy tank. We are careful to quarantine new tank mates, and have had this tank balanced and in harmony for a long time. These Ramshorn snails share the tank with a betta and an African dwarf frog, and some cherry shrimp and orange shrimp. The tank is in balance, with optimal PH, hardness, and nitrate levels (0). The temperature is a balmy 7 degrees. These snails are happy! In fact they have a habit if getting to the frog's algae pellets before him. :-)
