Overview

The best algae-eating snail for planted tanks — voracious on glass and leaves, and its eggs never hatch in freshwater, so no population explosions. Needs hard, mineral-rich water to keep its shell intact.

Tank Requirements

  • Minimum footprint: 5 gallons; a 10+ gallon tank gives real swimming room.
  • Preferred swimming zone: bottom of the water column.
  • Happy alone or as a compatible pair; avoid crowding with conspecifics.
  • Care level: easy.

Water Parameters

  • Temperature: 7080°F
  • pH: 78.2
  • Hardness: 820 dGH (Hard)

Stable parameters matter more than perfect ones — aim for consistency before chasing an exact number.

Temperament

Feeding

A herbivore / grazer — it needs plant matter and algae. Offer blanched vegetables, algae wafers, and a mature tank with surfaces to graze.

  • Yoyo LoachOccasional chasing or fin nipping is possible.
  • KribensisOccasional chasing or fin nipping is possible.

Stocking Considerations

  • Start from a 5 gallon minimum and plan the full group size before you buy.
  • Activity level is low, which affects how much of the tank it uses and how much it adds to the bioload.
  • Zoning matters: this species lives mostly in the bottom zone, so choose tank mates that occupy other levels.
