Bladder Snails (Physella acuta)

Physella acuta, commonly known as bladder snails, are small freshwater snails that can be found in a wide variety of aquatic habitats. In this blog post, we will take a closer look at the physical characteristics, habitat, and husbandry requirements of Physella acuta bladder snails.

Physical Characteristics:

Physella acuta bladder snails typically grow to be between 5 and 10 millimeters in length. They have a cone-shaped, spiraled shell that is yellowish-brown in color with dark stripes or markings. They have a small, pointed head with two tentacles, which they use to sense their surroundings.


Physella acuta bladder snails are native to Europe and can be found in a variety of freshwater habitats, including ponds, streams, and lakes. They are commonly introduced to new areas through the aquarium trade, and can also be found in artificial habitats such as ornamental ponds and water features.


Physella acuta bladder snails are relatively easy to care for in captivity, but they do have specific husbandry requirements. They require a clean, well-filtered aquarium with plenty of vegetation and hiding places. They prefer a temperature range between 68-78°F and a pH between 7.0-8.0.

Bladder snails feed on algae, plant matter, and decaying organic material. In captivity, they can be fed a variety of foods, including sinking pellets and algae wafers. It is important to not overfeed the snails, as this can lead to water quality issues.

Physella acuta bladder snails are prolific breeders and can quickly multiply in numbers if conditions are favorable. To control the population, it is recommended to limit the amount of food provided and remove any excess snails as needed. Bladder snails are also known to reproduce asexually, so it is possible for a single snail to start a population.


Physella acuta bladder snails are an interesting and important species that can be kept in captivity as pets or used as a food source for some fish species. By understanding their biology and husbandry requirements, we can better care for and appreciate this species. Whether you are a pet owner or a breeder, following the appropriate husbandry guidelines can ensure the health and well-being of your Physella acuta bladder snail population.
