This Danio species has an orange color. Blue, vertical stripes can be seen on the body of the fish. This pattern covers the whole body. At the end of the tail, the stripes will stop just before a blue blotch. The fins have, as mentioned before, a red coloration. This is clearest on the pelvic and anal fins. 
The differences between the sexes are rather hard to see. The females are somewhat rounder-bellied while the males are more colourful. However, when the fish get ready to mate, these differences become more clear. The females will become rounder, as they carry eggs by now. Furthermore, the males show their color at their best in order to impress others.
