These gorgeous Blue Mystery Snails (Pomacea Bridgesii) are great at cleaning algae off of glass, plants, and decorations. They are able to co-habit well with any fish, shrimp, or plants, and are completely peaceful. They will not eat live plants, only decaying or dying plants. These snails grow to 3 inches in diameter as adults!
Mystery Snails are generally much more active and have more "personality" than most other types of freshwater snails. They will often climb up to the water line to breathe air using their air tube (or "snorkel", as referred to by many hobbyists), so it's a good idea to make sure the water line in your aquarium isn't too high. When they reach adulthood, they may lay a clutch of eggs above the waterline, provided there are at least 2-3 inches of clearance between the top of the aquarium and the water-line.
To maintain optimum health, consider supplementing their diet with various vegetable or algae wafer supplements or Snello, and ensure that your water does not get below 7PH, as acidic water may start to corrode their shells. You can add crushed coral of calcium carbonate to your tank to naturally increase the PH of your water over time.
NOTE: The snails you will receive are juveniles and are generally around marble size, and the size and color of each Mystery Snail may vary slightly due to them being live creatures with their own unique hues, patterns, and personalities. These snails can grow up to 3 inches and generally may have a higher bioload than other smaller snail species, so please ensure your tank has at least 2.5 gallons of water per full grown snail and to do frequent water changes.
