Flame Scallop (Ctenoides scaber)
Flame scallops get mistaken constantly for the true bioluminescent "disco clam," but the flickering light show along this species’ mantle edge isn’t self-generated at all — it’s produced by rows of microscopic silica spheres that scatter and reflect ambient light as the mantle ripples, a passive optical trick rather than actual bioluminescence. Genuinely beautiful either way, but a demanding filter feeder that needs a mature tank with consistent phytoplankton to survive long term.
Care level: Difficult · Temperament: Peaceful · Max size: ~3" · Min tank: 30 gal, mature · Reef safe: Yes · Diet: Filter feeder, phytoplankton

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.
