Natural Habitat

Freshwater environments such as ponds, streams, and home aquariums, often attached to glass, rocks, or plants.

Diet & Feeding

Algae and biofilms; they graze on microscopic organic matter and diatom growth.

Behavior Patterns

Hermaphroditic; they move very slowly across surfaces using a muscular foot and can reproduce rapidly under high-nutrient conditions.

Risks & Benefits

Harmless to humans and pets; they benefit ecosystems by controlling algae growth, though they are often considered pests in aquariums due to their fast reproduction.
