Researchers have just discovered and described a new rainbow fish which hails from West Papua, Indonesia.

Ichthyologists, also known as fish scientists to us normal folk, Paradis, Pouyaud, Kadarusman and Sudarto are credited with the find and have dubbed the new kind of rainbow fish Melanotaenia fasinensis. They published this in a paper in the journal Cybium.

The new rainbow fish was found in the Fasin River, just about 25 clicks west of Lake Ayamaru on the West Papua’s Bird’s Head Peninsula.

The little guy was found floating about in a 1 meter deep, 4.5 meter wide stream, surrounded by flush greenery.

This rainbow fish lives over a substrate of gravel, and makes its home amongst limestone boulders and debris of fallen branches from the forest.

The Fasin River also boasts a myriad of other species such as sleeper gobies, and different types of crayfish.

The Bird’s Head Peninsula in Indonesia is considered a hotspot when one is going about and trying to find rainbow fish. There are many different kinds of rainbow fish which also call the place home, and they all seem to live in harmony with one another.

It’s good to see that the scientific world has not given up on seeking new kinds of this beautiful fish. Not only are they pretty to look at, but they are key to the survival of all the species in that ecosystem.

Some people have been trying to catch them and sell them off as pets, however an ordinance is in place telling people to refrain from such a practice.
