Quarantined | Cerith Snail

What “Quarantined” means

Every animal sold under this listing goes through YoCamron’s Aquatics full quarantine program — treated preventively for the common pathogens, observed daily, and confirmed eating — before it goes home with you.

Most livestock losses in this hobby aren’t bad luck. They’re pathogens that arrive with a new animal — ich, velvet, gill and body flukes, internal parasites — and stay invisible for the first 1–2 weeks while the animal is stressed from shipping. By the time you can see the problem, it’s in your display tank, and every animal you own is in the fight. Quarantine exists to run out that clock in our tanks instead of yours.

Our process

• Dedicated quarantine systems, separate from our display and sale tanks.
• Preventive treatment for the pathogens that actually kill new arrivals, instead of waiting for symptoms.
• Daily observation — breathing rate, body condition, behavior — so problems get caught while they’re still small.
• Feeding confirmation. Nothing goes home until it’s eating in front of us. An animal that eats is an animal that travels well.

Quarantined to order

Nothing we sell online is pre-quarantined and waiting on a shelf. Every quarantined animal is quarantined to order — your purchase starts the process, and the clock starts the day your animal reaches our facility.

For a saltwater invertebrate like this one, plan on up to 76 days before it goes home.

Add up to two more weeks in front of that. If we do not already have the animal in-house, sourcing it is the first step — and that time sits on top of the window above.

This is not a rush purchase, and it can’t be turned into one — the entire value of quarantine is time. If you need your livestock by a particular date, contact us before you order and we’ll schedule the arrival around it. If you need something this week, the non-quarantined listing is the honest choice. The full process — and how to decide which tier is yours — is explained in Quarantined vs Non-Quarantined.

The guarantees

• Shipped — Early AM Overnight only: 48-hour live arrival guarantee from confirmed delivery. Next Day Air (standard Overnight), 2-Day and USPS Priority carry no live arrival guarantee, on any tier.
• Local pickup or delivery: 28-day live guarantee — bring a water sample from your aquarium so we can test it before your livestock goes home with you.
• Maintenance clients: 60-day live guarantee on any livestock you buy from us, for as long as we service your aquarium on a plan of at least twice a month — weekly, every 10 days, or biweekly. Monthly plans carry 28 days. Nobody else in the trade puts that in writing.
• Sourcing: if the animal is not already in-house, add up to two more weeks in front of the window above — that applies on every tier.
• Claims: video of the sealed, unopened bag, opened on camera, with the animal on a white paper towel, inside the window.

Why quarantined is the right choice

If you have an established display tank, the math is simple: the premium on a quarantined animal is small next to the cost of treating — or losing — everything already in your tank. It also means you can skip running a hospital tank at home, which done properly is its own aquarium, its own months of patience, and its own chance to get something wrong.

The honest caveat: many of these species are also available from us non-quarantined for less. Those carry a 1-hour live arrival window on Early AM Overnight — or 24 hours on local pickup or delivery with a tested water sample — and no refunds, returns, or credits beyond that. There is also a middle rung: the Lightly Medicated listing gets one short prophylactic course and is covered for 24 hours on Early AM Overnight, or 7 days on local pickup or delivery with a tested water sample. Next Day Air (standard Overnight), 2-Day and USPS Priority carry no live arrival guarantee, on any tier. If you already run a proper quarantine setup at home, that’s a fair trade and you should take it. If you don’t, this listing is the right one. (You’ll sometimes see “quarantined” abbreviated as QT — same thing.)

Cerith Snails (Cerithium sp.) do their best work while you’re asleep — nocturnal by nature, they spend the night moving methodically through the sand bed and over rockwork, breaking down detritus and consuming diatoms, cyanobacteria, and decaying organic matter before it enters the nitrogen cycle as a nitrate precursor. By day they mostly stay buried in the sand or tucked into rockwork, so they contribute more to tank health than their daytime invisibility suggests.

They’re one of the more genuinely useful sand bed cleaners in a reef cleanup crew because they work the interface between sand surface and water column where a lot of organics accumulate — the zone that nassarius snails go deeper than and hermit crabs stay above. That ecological niche specificity means a mixed cleanup crew with cerith snails, nassarius snails, and hermit crabs covers the full range of sand bed maintenance more completely than any single species alone.

They don’t need target feeding in an established reef — the natural organic load in a typical reef tank is more than sufficient. In a bare or newly established system, occasional small amounts of sinking food placed at night help sustain them while the biological load builds up.

Scientific name: Cerithium sp. (several species sold as “cerith snail” in the trade)
Origin: Tropical Indo-Pacific and Caribbean — sandy reef zones, seagrass beds, and intertidal sand flats
Water parameters: Temp 72–80°F · Salinity 1.023–1.026 · pH 8.1–8.4
Tank requirements: 10 gal minimum; live sand substrate recommended
Diet: Herbivore/detritivore — algae, diatoms, cyanobacteria, detritus, and decaying organic matter
Compatibility: Reef safe; peaceful with all species; hermit crabs may target them for their shells
Husbandry note: Stock cerith snails at roughly 1–2 per 5 gallons of tank volume as a starting point. Overstocking any single cleanup crew species creates competition for food that leads to die-offs — a diverse crew at moderate density outperforms a large single-species crew.
