addition to a community tank and will school with similar looking fish.

Hengel Rasbora, Glowlight Rasbora.
Asia: NBorneo, Sumatra and Indonesia.
General Body Form:
This fish is often confused with Harlequin and espei rasboras. The
Hengel is the smallest of the three species. Not as stocky as the
In comparison to the Harlequin Rasbora the Hengel's Rasbora has a smaller
triangle with a faint orange line above its black spot. This orange
line is not present in the R.espei, which is also more reddish in colour
than the Hengel.
A small school of Harlequin Rasbora, notice the triangle size.
This is an omnivorous fish, so both vegetables and frozen and live food
should be given to vary their diet, they will also take flake food.
Will do best with plenty of swimming room as it is an active fish with
dense, tall plants around the sides and back due to their shy nature.
As the Hengel's Rasbora is a schooling fish, it needs a shoal of a minimum
6 fish, preferably more, but I have found they also school with Harlequin
Rasboras and espei rasboras. The shoal will establish a pecking order,
but won't cause any harm to each other and prove a good, peaceful community
