Chestnut Mystery Snails - (No Online Purchases)

Name: Chestnut Mystery Snail / Chestnut Apple Snail (No Online Purchases)

Scientific Name: Pomacea diffusa (formerly Pomacea bridgesii)

Description: A peaceful and attractive freshwater snail recognised for its rich chestnut-brown shell, often featuring darker spiral bands. Chestnut Mystery Snails are active scavengers that explore the aquarium, grazing on biofilm, soft algae and leftover food. Their interesting behaviour, attractive shell patterns and gentle nature make them a popular addition to planted aquariums and peaceful community tanks.

Origin: South America, particularly the Amazon River basin. The Chestnut variety is selectively bred for its distinctive shell colouration.

pH: Approximately 7.0–8.2

Temperature: Around 22–28°C

Adult Size: Approximately 4–6 cm

Lifespan: Approximately 1–2 years under suitable aquarium conditions.

Food: Omnivorous scavenger. Feeds on biofilm, soft algae, decaying plant matter and leftover food. Supplement with algae wafers, sinking snail pellets and blanched vegetables such as zucchini, spinach and green beans. Calcium-rich foods help maintain healthy shell growth.

Compatibility: Extremely peaceful and suitable for community aquariums containing non-aggressive fish, shrimp and other peaceful snails. Good tank mates include Tetras, Rasboras, Guppies, Corydoras and Neocaridina Shrimp. Avoid Puffers, Loaches and aggressive Cichlids that may attack or eat snails. Mystery Snails generally leave healthy aquarium plants alone when adequately fed.

Habitat: A well-established freshwater aquarium with stable water conditions, aquatic plants, driftwood and smooth decorations. Chestnut Mystery Snails prefer moderately hard, calcium-rich water to support healthy shell development. 

 Provide a secure lid and a small air gap above the waterline, as Mystery Snails breathe atmospheric air and may climb above the water to lay eggs. Gentle filtration, regular water changes and good water quality are essential. Avoid copper-based medications, as these are toxic to snails.
