Quarantined | Hairy Hermit Crab (Dardanus sp.)

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.)

Hairy Hermit Crabs (Dardanus sp.) are named for the dense, bristle-like hairs covering their legs — a likely adaptation that helps break up their outline against algae-covered rock, functioning as natural camouflage in the same way a ghillie suit disrupts a silhouette. In the reef, they’re generalist scavengers that clean up leftover food, pick at nuisance algae, and turn over detritus in rockwork crevices that other cleanup crew members don’t bother reaching.

Like every hermit crab, they need an appropriately-sized shell to live in and they’ll outgrow their current one periodically. The solution is simple but important: keep a handful of spare empty shells of varying sizes in the tank so they can upgrade without needing to evict a snail to do it. A hermit crab actively bothering snails is almost always a housing problem — the right size shell available solves it. Hardy, low-maintenance, and genuinely useful cleanup crew once that detail is covered.

They’ll opportunistically pick at soft corals if underfed, so ensure scavenging opportunities are adequate. A well-fed hermit is a reef-safe hermit.

Scientific name: Dardanus sp.
Origin: Indo-Pacific and tropical Atlantic — rocky reef zones, rubble areas, and hard-bottom habitats
Water parameters: Temp 72–80°F · Salinity 1.023–1.026 · pH 8.1–8.4
Tank requirements: 10 gal minimum; provide several empty shells in a range of sizes
Diet: Omnivore scavenger — detritus, algae, leftover food; target-feed sinking foods if other scavenging is limited
Compatibility: Generally reef safe; may bother soft corals if underfed; will attempt to evict snails if appropriately-sized empty shells are unavailable
Husbandry note: Stock 3–4 appropriately-sized shells per hermit crab and replenish them as they’re claimed. This single step eliminates most hermit-related tankmate conflicts and is the most frequently overlooked part of hermit crab care.
