3 BLACK MYSTERY SNAILS

Black Mystery Snails (Pomacea diffusa) are one of the most popular freshwater snails for aquariums, prized for their deep black shells, hardy nature, and helpful cleanup abilities. They are peaceful, low-maintenance, and make an excellent addition to community tanks with fish, shrimp, and live plants.

Appearance

Black Mystery Snails feature glossy, dark shells ranging from jet-black to chocolate brown. They grow up to 2–3 inches in diameter, making them larger than many other freshwater snails. Their foot and antennae are also dark-colored, giving them a sleek, striking look that contrasts beautifully in planted aquariums.

Tank Requirements

– Tank size: 5–10 gallons minimum per snail
– Water temperature: 72–82°F
– pH: 7.0–8.0, with calcium-rich water to prevent shell erosion
– A secure lid is required, as they can climb above the waterline

Behavior

Black Mystery Snails are peaceful grazers that spend their time exploring, climbing glass, and feeding on algae or detritus. They breathe through gills but also extend a siphon tube to the surface for air, a unique behavior that makes them fun to watch.

Diet

They feed on algae, leftover food, and decaying plant matter but should also be given supplements: algae wafers, blanched vegetables like zucchini and spinach, shrimp pellets, or calcium-rich foods to maintain strong shells.

Breeding

Mystery Snails lay clutches of eggs above the waterline, often pink or white in color. Eggs can be removed if breeding is not desired, preventing overpopulation.

Benefits in the Aquarium

– Effective algae control
– Clean up leftover food and waste
– Add movement and beauty with their bold black shells
– Safe with shrimp, snails, and peaceful community fish

Black Mystery Snails are an attractive and functional addition to any freshwater aquarium, providing natural algae control, personality, and low-maintenance care while enhancing the overall balance of your tank.
