Introduction to Aquacultured Collonista Snail (Miniature Algae Grazer & Self-Sustaining Cleanup Crew)
Collonista snails (Collonista spp.) are tiny, reef-safe algae eaters that help control diatoms, film algae, and biofilm in saltwater aquariums. Often referred to as "mini turbo snails", they resemble Astrea snails but stay small and reproduce naturally in aquariums. We aquaculture Collonista snails in-house, ensuring healthy, parasite-free specimens that are fully acclimated to reef tanks. These nocturnal grazers are excellent for nano tanks and large reef systems alike, as they actively feed at night while staying hidden during the day.
Care Requirements
Care Level: Easy – Requires little maintenance Minimum Tank Size: 10+ gallons Aquarium Setup: Requires live rock and glass surfaces for grazing Collonista snails are hardy and adaptable, thriving in a variety of reef environments as long as algae or biofilm is present.
Diet & Nutrition
Collonista snails are herbivorous grazers, consuming a variety of nuisance algae. Diet: Herbivorous – Prefers diatoms, film algae, and biofilm Recommended Foods: Naturally occurring algae on rocks and glass Diatoms and film algae Supplemental seaweed sheets if algae is scarce Because they continuously graze throughout the night, they provide consistent algae control without overpopulating the tank.
Lifespan & Growth Rate
Lifespan: 2-4 years Growth Rate: Slow – Typically reaches up to ½ inch Collonista snails reproduce naturally in reef aquariums, gradually increasing their population over time.
Temperament & Compatibility
Temperament: Peaceful – Does not interact with or harm tankmates Reef Safe? Yes – Does not harm corals, fish, or invertebrates Avoid housing them with predatory species such as: Triggers Pufferfish Large wrasses These fish may pick at or eat Collonista snails, reducing their population.
Common Challenges & Considerations
Nocturnal Behavior: Typically only seen at night, hiding in rock crevices during the day. Slow Population Growth: While they reproduce in tanks, populations grow gradually over time. Very Small Size: May not be noticeable but actively contribute to algae control. Their natural breeding cycle and constant grazing make them a low-maintenance yet effective cleanup crew member.
