Betta Rutilan, a member of the coccina family is the next beautiful fish in this branch. This is a wild male, among several fishes caught near the Indonesian border in Sarawak near a clear fast moving stream. Interestingly, the habitat seems to be different from Betta brownorum's.
Behavior is also different from B. brownorum as it is aggressive towards each other regardless of sex. This is a good jumper (to the author's dismay of losses) so the water level in their tanks have been lowered to prevent them from leaping out. This specie's habitat is threatened by encroaching agricultural activities.
PS : Sorry about the hazy image as it is housed in a very old aquarium, with lots of scratches on the front panel. I will have new images posted up soon on http:// www.flickr.com/eldredsawk/
