Betta pallifina montoi is a very aggressive subspecies of unimaculata that is collected from the Montoi area near Puruk cahu central Kalimantan Indonesia. The closest waterway is the Barito river. Montoi is a very small village with a estimated 20 families residing in it as quoted by my trusted source Hendry Sutrisno. In my experience these Bettas are very difficult to pair. Breeding isn't that difficult if you are able to get the pair to stand each other. Typical of the complex and like most wild bettas a cool water change and good meaty foods is enough to get them to spawn. In my case the montoi male drove the female away and was overly aggressive. I never felt like the female was safe to leave unattended. I never got the pair to bond so the fish stayed individually in 10 gal tanks with huge sponge filters, tight fitted lids a water temp of 73 F and a PH of 5.5. I believe that Betta pallifina montoi needs a lot of real estate to be housed together. Maybe a group of 1 male and 3 females in a 48" long tank like a 55 gal or 75 gal could yield good results. Maybe the use of dither fish like rasboras or danios can help distract aggression. The use of wood and tubes as hides always helps and I will surely keep trying because Betta montoi has become my favorite Betta in the unimac complex.
