Quarantined | Celestial Pearl Danio (Danio margaritatus)

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 freshwater animal like this one, plan on up to 60 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.)

The Celestial Pearl Danio (Danio margaritatus) wasn’t formally known to science until 2006 — formally described from a single locality in Shan State, Myanmar — making it one of the more recent entries to the aquarium trade and a species that went from scientific discovery to widespread captive breeding in a matter of years. That dark blue-black body covered in small gold spots, with orange-red banded fins on males that deepen during displays, looks genuinely more like a piece of jewelry than a fish, which explains the rapid adoption.

Despite the fragile appearance, they’re genuinely hardy once established in appropriate conditions — the fragility reputation largely traces to newly-imported wild specimens before captive breeding stabilized the trade. Tank-raised D. margaritatus adapt readily to standard soft-to-moderately-hard freshwater and eat eagerly. Males intensify their colors dramatically during courtship displays, flaring fins at rivals and females in a way that shows off that banded pattern to full effect.

They’re best kept in groups in a heavily planted nano tank. The planted environment and subdued lighting actually enhances the spotted pattern — under bright, bare-tank conditions, the spots read as pale and the fish looks washed out. More plants, darker substrate, lower light, bigger group.

Scientific name: Danio margaritatus
Origin: Shan State, Myanmar — shallow, clear, heavily vegetated ponds and pools at highland elevation
Water parameters: Temp 68–78°F · pH 6.5–7.5 · GH 5–15 (adaptable; prefer moderate hardness)
Tank requirements: 5–10 gal minimum; planted nano tank; groups of 8–12+ recommended
Diet: Omnivore — micro-pellets and small flake; supplement with baby brine shrimp, daphnia, and micro-worms
Compatibility: Peaceful nano fish; must be kept with equally small, non-predatory species
Husbandry note: Males competing for females is where the color display peaks — a group of 8+ with a slight male-to-female bias of 1:2 produces the most consistent display behavior and the best looking tank.
