Bladder Snail Care Guide
Physella acuta · Freshwater Invert
What Bladder Snail look like
Physella acuta is a small freshwater snail with a thin translucent amber to brown shell and soft gray body. The shell is oval and typically sinistral, meaning the opening is on the left when oriented in standard shell view. Long fine tentacles and a small size make it easy to separate from mystery snails and nerites.
Behavior & temperament
Bladder Snails are peaceful scavengers and algae grazers. They reproduce readily in aquariums, often arriving as hitchhikers on plants. Their numbers are a useful signal of excess food or detritus, and they are valuable for beginner identification because many aquarists first notice them unexpectedly on glass or leaves.
Diet & feeding
Bladder Snails graze algae film, biofilm, soft decaying plant matter, leftover food, and detritus. They usually do not harm healthy plants, but populations boom when excess food is available. Calcium availability supports shell growth.
Behind the name
Physella is related to bladder-like shell form; acuta means sharp or pointed.
Plan your tank
Check the numbers before you buy: tank volume, a stocking plan, cycle progress, water changes, and your ongoing care routine.
