The other face of Osphronemus Septemfasciatus

Osphronemus Septemfasciatus can also show the bar pattern of Osphronemus Goramy, I only notice this phenomena when the fish is around 14". Are these pattern emerged only when they are sub adult?
When I was searching for the O.Sep I came across a variant of Osphronemus Goramy Kapuas hulu, they show correlative pattern of the O.Sep. The hulu kapuas var O.Goramy is rather confusing as they are so similar to the O.Sep except for the concave bar.

After encountering my O.Sep forming the same bar pattern, I can't help but wonder if the O.Goramy var hulu kapuas that I came across earlier are they the same fish? I do not have a clear photo but the only way to identify them apart now is the cheek line pattern.

It will be tricky to ID the O.Sep from the O.Goramy hulu kapuas.

O.Sep forming the concave bar, they show this bar pattern according to their mood and will revert back to their original tappered bar.

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. The truth is you need to abused it, hence Marulioides care isn't exactly the correct terms to use. 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

Malaysia Golden Arowana Challenge

This project was back in 2014, Kitty Lai wanted to know if I still have it to groom Arowana fish. So I picked a so so XB which I bid only for RM400. Its not a fish which you will find appetizing, the fish has slight PLJ, crossed barbel, very thin/translucent gold. unformed pearlies Very transluscent gold crossed barbel Pictures above are what the seller sent me Fished Arrived First Day fish in my tank First fixed was having the barbel cut and take note of the slight PLJ PLJ - Protruding Lower Jaw 2 weeks later in the dark tank, gold become more intense and I needed to pump the fish up to reduce the PLJ effect. Tanning project begins and when I went to find for tanning lights only did I realized how long it had been since I left the Arowana scene. TFC factory had closed down, for your information TFC T8 light is one of the best tanning light for arowana. I asked all the shop and they say everyone is using LED tanning light. Forget about
