The Pearl Danio comes from clear swiftly moving streams and rivers in Myanmar (formerly known as Burma), Thailand, and Sumatra. In nature, they feed primarily on insects.
Pearl Danios are well suited for community aquariums and get along with any peaceful fish. They are tolerant of a wide range of water conditions, which also make them suited to combining with a variety of other fish. As a schooling fish, they should be kept in groups of at least four, preferably more. Males will show their best colours if there is at least one female present.
The Pearl Danio is accustomed to a strong water current and ample swimming room. Because they require a slightly higher oxygen level than other Danios, good filtration is important. Pearls tolerate cooler temperatures well and may be kept in an unheated tank. They swim at all levels, but due to their tendency for jumping, the tank should be well covered. Longer tanks are preferable, with plants along the back and sides. Their iridescent colours are most visible under reflected, overhead lighting. They are particularly fond of early morning sunlight. Although undemanding about water parameters, they do best in neutral water that is soft to slightly hard.
Pearls will accept all types of living, frozen, and flake food. To maintain good health, feed good quality tropical flake or granulated food, as well as frozen foods such as mosquito larvae, brine shrimp and Daphnia.
Females are larger overall, and fuller-bodied than the makes. It is not unusual for females to be more robust than the males. Males are smaller, slimmer, and more brightly colored. The males often show a red tint along the ventral aspect.
