The genus Danio is very similar to Brachydanio, differing only in details relating to fin-ray and lateral-line features. More obvious is the larger size attained by Danio species.
There is still considerable debate as to whether D. aequipinnatus and D. malabaricus are one and the same species or whether, at least in Sri Lanka, they constitute two very closely related species. Most authorities believe them to be the same fish. Several color varieties, including a golden one, are available.
- Danio malabaricus
- Rasborinae (Danioninae)
- Southwest India and Sri Lanka.
- Up to 6in (15cm) reported, but usually considerably smaller.
- Very active peaceful shoaler that prefers the upper layers of the water column.
- Wide range of foods accepted.
- Roomy with well-fitting cover, open swimming spaces, and plant thickets. Water chemistry not critical but quality must be good. Temperature range: 72-75°F (22-24°Q; slightly highfr for breeding.
- Female scatters eggs among fine-leaved vegetation. Hatching takes about 1 day.
