Pearl Danio (Danio albolineatus)

Danio albolineatus carries a genuine pearlescent, opalescent sheen across the body that shifts subtly with the angle of light, distinct from the flat stripes of its zebra danio cousin despite sharing the same genus and the same restless, fast-swimming temperament. It's an easy fish to underestimate in a bare dealer tank and a genuinely striking one under real aquarium lighting in a group. Peaceful, quick, and a solid beginner schooler.

Care level: Easy · Temperament: Peaceful, shoaling · Max size: ~2.5" · Min tank: 20 gal · Diet: Omnivore, flake/pellet
