Species description

Care, breeding and tankmates

Invertebrate profile

Diet

Herbivore

Vittina coromandeliana acts primarily as a detritivore and herbivore, endlessly moving over surfaces in search of food. They are renowned for their ability to consume various forms of problematic algae and biofilm. Sinking algae wafers can be offered if the tank is too clean to support them.

Ecological role

Herbivore

As a member of the cleanup crew, Vittina coromandeliana performs an essential role in keeping hard surfaces pristine. They scrub algae from glass, rocks, and decorations without harming established plant life. Their waste also breaks down easily to nourish the biological filter.

Shock sensitivity

Medium

Vittina coromandeliana benefits from a gentle acclimation period to equalize temperature and water chemistry. A sudden change in salinity or pH can cause them to clamp their operculum tightly and refuse to move. Patience during introduction ensures they quickly begin exploring the tank.

Calcium and minerals

High

Vittina coromandeliana has a high demand for calcium to construct and maintain its dense shell. In water with poor mineral content, their shells can become pitted, thin, and brittle. Maintaining a stable pH and sufficient calcium levels is crucial to their long-term survival.

Molting

Yes

Unlike crustaceans, Vittina coromandeliana does not undergo a molting process. Instead, it continuously adds new layers of calcium carbonate to the edge of its existing shell as it grows. Visible growth rings on the shell can indicate changes in diet or water chemistry over time.

Reproduction

Oviparous

Many snails in this category require specific, often brackish, conditions for their eggs to successfully hatch. While they may lay resilient egg capsules on hard surfaces, these rarely develop in a standard aquarium. This makes Vittina coromandeliana excellent for aquarists who want to avoid overpopulation issues.

Compatibility & tankmates

Peaceful

Vittina coromandeliana is completely defenseless, relying solely on its hard shell to deter aggression. It should never be housed with specialized snail-eating predators like pufferfish or loaches. They mix perfectly well with small fish, peaceful shrimp, and other serene invertebrates.
