Hara, like most other erethistids, are found in lower-temperature (ca. 20-22°C), fairly swift streams/rivers. They are difficult to sex and their natural diet consist of invertebrates.
Not too difficult to maintain in the aquarium as long as you have well-oxygentaed water and moderate water temperatures.
They are difficult to sex and have not been bred in the aquarium, to my knowledge.
The info for Erethistes is largely applicable.

tks silurus...can i put u to the test and ask u if u know what size they grow up to as well as tankmates eg..corys??

The size it reaches to depedns a lot on your species, as quite a number of them are confused with Hara hara. The "real" H. hara (I use quotation marks because no one is sure what the real H. hara is) reaches about 2" (5 cm). There is a larger species (sometimes referred to as H. filamentosa, but is probably Erethistes; see the Shane's World article) that reaches about 5" (13 cm), and a much smaller one (often referred to as H. jerdoni) maxes out at 1.5" (4 cm).
As for tankmates, they are OK with corys, but you will need to use a species that prefers cooler temperatures (Corydoras barbatus comes to mind, but maybe Ian can help me out with listing a few more).

tks for all the info...greatly appreciated!

I am told by someone who has collected them and read in other sources that both Hara hara and Hara jerdoni are typically found in slow moving waters.
