Pearl Danio – Danio albolineatus
The Pearl Danio (Danio albolineatus) is a lively and peaceful freshwater schooling fish admired for its subtle pearl-like iridescence. Under good aquarium lighting, this species can show soft hints of pink, blue, gold, and silver as it moves actively through the tank.
Pearl Danios are hardy, beginner-friendly, and excellent for peaceful community aquariums. Their constant movement adds activity to the upper and middle levels of the aquarium, especially when they are kept in proper schools.

Tank Setup
Pearl Danios do best in aquariums with open swimming space, stable water quality, and gentle to moderate water flow. A planted aquarium with open areas for schooling works very well and can help them feel more secure.
Keep Pearl Danios in groups of 6 or more to encourage natural schooling behavior, reduce stress, and help bring out their best activity and coloration.
Diet & Feeding
Pearl Danios are easy to feed and accept a wide variety of foods. Offer quality flakes or micro pellets as a staple diet, along with frozen or live foods such as daphnia, brine shrimp, and bloodworms for variety.
Best Tankmates
Pearl Danios are peaceful community fish and do well with other active, non-aggressive species. Good tankmates may include other danios, tetras, rasboras, Corydoras, livebearers, and peaceful gouramis.
Avoid aggressive fish or very slow, long-finned species that may become stressed by the danios’ constant activity. While Pearl Danios are generally peaceful, they may nip long fins if crowded, stressed, or kept in too small of a group.

- Freshwater community aquariums
