Pearl Danio

A perfect beginner's fish, hardy and showy when kept in schools. Aaron Norman


Danios are very busy fish and perfect for the aquarist who likes a lively aquascape with lots of movement. The Pearl Danio is a peaceful, schooling species. The natural version of the Pearl Danio is a lovely "mother-of-pearl" species, with a pinkish-blue iridescent body. There is also a gold variety, called the Yellow Danio, which is derived from aquarium-bred stock.

Habitat: D. albolineatus does best in a well-lighted aquarium planted on the sides and back, with lots of room in the center to swim.

Carnivore. In the wild, their diets consist primarily of insects and insect larvae, and in the aquarium they will accept most commercial aquarium foods, including good-quality tropical flake or granular food, as well as frozen and live foods such as Tubifex, mosquito larvae, brine shrimp and Daphnia. Will benefit from regular feedings of color-enhancing foods.

Aquarium Compatibility

Acquire a group of at least three and house with other mild-mannered fish. These are jumpers, so a tight-fitting cover is a must.


During frantic chases, they scatter non-adhesive eggs that fall to the bottom. Shallow water and a marble-covered bottom will prevent the parents from eating their own spawn.


A long tank is ideal for providing the room they need to stretch their fins.
