The pearl danio is a tropical fish belonging to the minnow family Cyprinidae. Originating in Sumatra, Myanmar, and Thailand and Vietnam, this fish is sometimes found in aquariums by fish-keeping hobbyists. It grows to a maximum length of 2.6 inches and lives for around five years.

Originating from fast-moving streams and rivers, the pearl danio is accustomed to strong water currents. Because they require a slightly higher oxygen level than other danios, good filtration is important. Pearl danios tolerate colder temperatures well and may even be kept in an unheated aquarium. They swim at all levels, but due to their propensity for jumping, the tank should be well covered.

Pearl danios will accept all types of live, frozen, and flake food.To maintain health, feed good quality tropical flake or granulated food, as well as frozen and live foods such as tubifex, mosquito larvae, brine shrimp, and daphnia.
