Green Nassarius Snail
Green Nassarius Snail
Nassarius snails track food by scent, not sight, using a siphon sensitive enough to pick up dissolved amino acids in the water from across the tank — drop in a piece of food and watch a dozen of these erupt out of the sand almost simultaneously, all converging on the same spot within seconds. Between meals they stay buried, quietly working through detritus the rest of the cleanup crew never reaches.

When it ships
Most non-quarantined stock goes out the week you order. If we do not already have the animal in-house we source it first — allow up to two weeks for it to reach us. Live animals leave Monday and Tuesday, and Early AM Overnight is the only service that carries a live arrival guarantee.
The live guarantee
Shipped Early AM Overnight: a 1-hour DOA window from confirmed delivery, and nothing beyond it. Next Day Air and 2-Day carry no live arrival guarantee, and neither does USPS Priority. Local pickup or local delivery: 24 hours, if you bring a water sample from your aquarium and we test it before the animal goes home. Maintenance clients: 60 days when we service the aquarium at least twice a month, 28 days on a monthly plan.
