Ask Finn

Small, olive-coloured nerite with a smooth shell. Excellent algae grazer that won't eat healthy plants. Does not reproduce in freshwater. A reliable and undemanding member of any planted tank clean-up crew.

Care Guide

Diet

Olive Nerite Snails are primarily algae grazers that consume algae from surfaces, plants, and decorations throughout the day. They will also accept blanched vegetables like zucchini and spinach 2-3 times weekly as supplements. Feed sparingly in established tanks with adequate natural algae; in newer or heavily cleaned tanks, provide algae wafers or vegetable matter to prevent starvation.

Behavior

These snails are nocturnal and spend most of their time grazing on tank surfaces, making them excellent cleanup crew members. They are completely peaceful and non-aggressive, though they may occasionally climb out of the water if conditions are poor or the tank is overcrowded. They move slowly and deliberately, leaving visible trails as they feed.

Breeding

Olive Nerite Snails do not breed in freshwater aquariums, making them ideal for planted tanks where population control is a concern. Breeding requires brackish water conditions that are impractical for most home aquariums. This non-invasive reproduction is a major advantage over other snail species.

Common Diseases

Shell Erosion

Symptoms

Pitting, chalky appearance, or deterioration of shell surface

Treatment

Increase calcium supplementation through cuttlebone or calcium-enriched foods; maintain stable pH 7.0-8.5 and perform regular water changes

Parasitic Infections

Symptoms

Lethargy, withdrawn behavior, visible parasites on shell or body

Treatment

Quarantine affected snails; perform 25% water changes; avoid copper-based treatments which are toxic to snails

Bacterial Shell Disease

Symptoms

White spots, fuzzy growth, or discoloration on shell

Treatment

Improve water quality through frequent water changes; ensure adequate aeration; remove and isolate severely affected individuals

Starvation

Symptoms

Inactivity, failure to graze, visible weight loss

Treatment

Supplement with algae wafers or blanched vegetables if natural algae is insufficient; ensure tank has adequate algae growth
