Zonobe Rainbowfish Rheocles vatosoa

The Zonobe Rainbowfish, also called Vatosoa Rainbowfish, is native to a now-protected habitat of the Lohoko River basin in northeast Madagascar, but remains endangered from invasive species.

They can grow to 8cm long. Males grow dark red-black fins when breeding.

Like much of Madagascar's wildlife, they are endangered by habitat loss from logging and ricefields, and from invasive species in their remaining habitat.
