“Mini Trochus” – Collonista verruca (Captive Bred)

Description

Collonista verruca is a tiny, reef-safe snail valued in saltwater aquariums for its algae-eating abilities. Typically reaching only 2-–5 mm in size, these nocturnal snails resemble miniature turbo snails and are often found in live rock or introduced via coral frags.

In reef tanks, Collonista verruca serves as a beneficial member of the clean-up crew. Their diet consists primarily of:

• Microalgae (including film and turf algae)

• Diatoms

• Biofilm

• Detritus and leftover organic matter

They do not consume corals, macroalgae, or other invertebrates, making them completely reef-safe. Their slow and steady grazing helps maintain clean surfaces on rocks and tank walls. These snails reproduce in aquaria but do so at a manageable rate, contributing to biodiversity without becoming a nuisance. Many hobbyists consider their presence a sign of a healthy, well-balanced reef system.
