Species description

Care, breeding and tankmates

Invertebrate profile

Diet

Biofilm grazer

These snails are voracious scavengers that feed almost exclusively on detritus, uneaten fish food, and decaying plant matter trapped within the substrate. They are incredibly beneficial to planted tanks, as they completely ignore healthy vegetation and focus solely on eliminating rotting organic waste. In a typical community aquarium, they rarely require targeted supplemental feeding, easily subsisting on leftover food.

Ecological role

Scavenger

Quilted melania perform a critical ecological role in the aquarium by constantly burrowing through the sand or gravel, effectively acting as earthworms of the aquatic world. This relentless churning prevents the substrate from compacting and entirely eliminates the risk of toxic, anaerobic gas pockets forming. They are unparalleled in their ability to maintain a clean, highly aerated, and biologically stable substrate.

Shock sensitivity

High

Tarebia granifera is arguably one of the most adaptable and indestructible snails in the aquarium hobby, capable of surviving broad fluctuations in temperature and water quality. While they are highly resistant to shock, a standard drip acclimation is still recommended to ensure a smooth transition to a new tank. They are often the first to colonize new setups and can easily survive the cycling process.

Calcium and minerals

High

To maintain the rugged, heavily textured integrity of their conical shells, quilted melania require a moderate supply of dissolved calcium in the water column. In extremely soft or acidic water, their shells will gradually pit and erode, though they often survive these conditions better than most other snail species. Providing crushed coral in the filter ensures their shells remain strong and aesthetically pleasing.

Molting

Shell growth

As gastropods, quilted melania do not molt or shed their shells at any point in their lifecycle. They grow by continuously secreting new, calcified layers along the aperture of their shell, steadily increasing the length and width of their distinctive conical shape. This continuous growth pattern relies on a steady intake of environmental calcium.

Reproduction

Oviparous

This species is parthenogenetic, meaning a single female can reproduce prolifically without the need for a male, giving birth to live, fully formed miniature snails. Their population can explode rapidly if the aquarium is overfed, making them an excellent indicator species for excess nutrient accumulation. Managing their numbers relies entirely on controlling the amount of leftover food and detritus available in the tank.

Compatibility & tankmates

Peaceful

The quilted melania is a completely peaceful invertebrate that will never bother fish, shrimp, or other snail species. Their thick shells and tendency to burrow keep them safe from many casual predators, though dedicated snail-eaters like assassin snails, pufferfish, and large loaches will actively hunt them. They are an ideal, low-maintenance addition to virtually any freshwater community or planted aquarium.
