This is a much more recent introduction than the Pearl Danio (B. albolineatus), first making its appearance in the mid-1950s. Although quite widely available, this danio is not kept as often as some of its nearest relatives. Like them, it is a beautiful, active jumper.
Other common name
- Blue Danio
- Rasborinae (Danioninae)
- Restricted to 2 islands in Thailand.
- Up to 2in (5cm).
- Active shoaler; excellent jumper.
- Most foods accepted.
- A well-covered aquarium with ample swimming areas should be provided, with no tall plants obstructing this space (tall plants are best arranged around the sides and back of the aquarium). Water chemistry is not critical, but overall quality must be good. Temperature range: 72-77°F (22-25°C); a little higher for breeding.
- Eggs are scattered, primarily, over the substratum. Hatching can take up to 4 days. Will hybridize with its closest relatives.
