Albino Millennium Rainbowfish (Glossolepis pseudoincisa)
Iriatherina werneri, the threadfin rainbowfish, grows genuinely delicate, thread-like extensions off the dorsal and caudal fins that are easily the most fragile finnage of any rainbowfish in the trade, prone to damage from boisterous tankmates or rough decor. This albino line strips out the usual body pigment while keeping those signature threadfins intact. Sold as a pair, best suited to a calm, well-planted school where those fins can trail freely without getting nipped or snagged.
Care level: Moderate · Temperament: Peaceful, shoaling · Max size: ~1.5" · Min tank: 20 gal · Diet: Omnivore, small flake/micro foods

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.
