Osphronemus Septemfasciatus changing pattern video

This video demonstrate how the Giant Borneo gouramy changes its pattern according to its mood. It can formed the common Giant Gouramy concave pattern and switched to the Giant borneo gouramy tappered pattern at a snapped of a finger.

I've never encountered a fish that can change its pattern to disguise as another species. Why do they display this behavior?

The science behind Channa Marulioides colors and pattern

Channa Marulioides is the chameleon of the fish, they are the champion when comes to color changing abilities. In a split second they can change from greenish brown to yellow and to orange. They can change their eye color from black to bright red. Observe your Channa Marulioides and you can see they greet you with bright yellow colors doing the maru dance, they flashes their bands to the highest contrast. The body colors are intense and their eyes bright vampire red in colors. When they are tone down and just swim about their business you notice the color is dull when they are in mid water, and suddenly sinking to the bottom with bright orange (depending on the var and PH) they keep changing and flashing their bands and patterns. But the black and white flowers will remain so in whichever mood they display. Also take note that maru shows their best colors mostly at midnight. Each Channa Marulioides comes in its own unique pattern of bands and flowers, like a fingerprint, I beli...

Marulioides Care Part 1 (Bunga)

I've been reluctant to write this but many had asked me to post how to take care of marulioides for maximum performance.

Channa Marulioides is found in most part of malaysia, lakes, pond, streams, rivers, but one thing most fisherman realized are those caught in swamp, I mean really dead stagnant peat swamp. Waters that are near black in color most time the fish had tremendous performance, beautiful colors and a lot of flowers. From this theory many tried replicating the conditions with low ph and so on. I've experiment many ways of keeping marulioides and I can concur to this, Low PH meaning Ph5 and below, I usually keeps mine ard PH4 or maybe lower, because my test kit can only measure till 4 and cant read anything lower. Low PH produce beautiful coloration. As for the bunga, yes everybody wants to know this, there is no tricks, just lots and lots of experiment. It i...

Understanding Indonesian Marulioides Variant

I would like to introduce you to some of the beautiful Channa Marulioides from Indonesia and at the same time clarify the complexity and the confusion as best I can. what is Marsum, Marbor, kalimantan, borneo, sp borneo, No.1 Marsum - Marulioides Sumatera Blue Marulioides not to be confuse with Channa Melanoptera Channa Marulioides Sumatera variant is very similar to the Malaysian variant. There is also another var found there known as Blue Maru which is greyish blue in color. No.2 Marbor - Marulioides Borneo known in Indonesia or Marulioides Kalimantan or Kali by Malaysian and Singaporean. The double line The 999/eee The yy + double line Now Kalimantan is very complex and has many variant. They comes in the 2 line bands form, the 999/eee form, the YY + double line form. But one of the key factors to tell them apart from sumatera, malaysia and thai variant is the middle exposure. The key to ID kalimantan is t...
