Mini Trochus Snails
Collonista spp. – The Mini Trochus Snail is a ravenous herbivore bred and raised at Biota Florida. These inverts make great additions to your clean up crew as they eat film algae on your glass and even some Cyanobacteria and Diatoms. These snails are extremely tiny even as adults. They’re perfect for nano or tanks, but they’re also great for large tanks because they can fit into crevices in rocks and places larger snails can’t reach.
These snails will reproduce in your tank, unlike the majority of other snails. This species is incredibly hardy and forgiving.
These snails are small enough to fit in pumps and plumbing, but with your regular cleaning they’re manageable.

I added a few Mini Trochus snails to my 10-gallon tank and they’ve been cleaning the glass and substrate effectively. They’re tiny but active, and I’ve noticed less algae buildup since introducing them. They seem to reproduce naturally, which is a bonus.
Richard Taylor –
These snails fit perfectly in the tight spaces of my tank. I didn’t expect them to eat so much film algae, especially in hard-to-reach areas. They’re easy to maintain and don’t cause any issues with water chemistry.
Amy Morrison –
Great for a small tank. The snails are very active and clean up algae efficiently. I’ve seen them reproduce, which means they’ll keep the tank tidy long-term without needing to buy more.
