Snail, Bladder


Physella acuta

Introduce bladder snails to your aquarium, where they serve as both natural cleaners and nutritious feeder snails. These diminutive yet diligent creatures are valued for their algae-eating prowess, helping to maintain a balanced aquatic ecosystem by consuming excess algae, detritus, and leftover fish food. Beyond their role as cleaners, bladder snails are also a nutritious source of food for many aquarium inhabitants, including fish, amphibians, and invertebrates. With their dual purpose as cleaners and feeder snails, bladder snails offer aquarists a convenient and sustainable solution for promoting a healthy and thriving aquarium environment.
