Danio | Pearl Danio (Danio albolineatus)

The Pearl Danio, scientifically known as Danio albolineatus, is a lively and peaceful freshwater schooling fish admired for its subtle pearl-like iridescence with hints of pink, blue, and gold. Under good lighting, these fish shimmer beautifully as they move in groups.

Pearl Danios are extremely hardy and beginner-friendly, making them an excellent choice for community aquariums, planted tanks, and larger nano setups. Their constant activity adds motion to the upper and mid levels of the aquarium, and they thrive when kept in proper schools.
