Tail biter



This is a behavior you don't often get to see, mainly because this means the fish is devalue and most people will choose to keep quiet about it. Out of maybe a 1,000 fishes you will find one tail biter, as its name suggest they attack their own tail. As to why exactly they do this is unsure and this crazies is not restrict to Channa Marulioides alone as Arowanas behaves the same sometimes. Some will say they are lonely or hungry, but as you all know I was left with 4 Terengganus and 4 of them is kept in identical environment, single tank fed the same food kept in the same PH and lightings.

From my many years in keeping Channa Marulioides this is the 2nd pc tail biter that I've actually encountered. I've swapped the fish tank with another Terengganu as I was wondering if the tank reflection is causing the self inflicting wounds but the fish that took its place behaves normal and this fish continue to attack its own tail.

I've also tried raising the PH to PH7 and I still see him chasing his own tail. From my previous experience the only way to stop this behavior is to comm the fish. When he is left distracted he will finally leave his tail in peace or a piece. 

A member has suggested high flow rate will stop this behavior which is a possibility as my previous comm tank was with high flow rate. I will try this experiment before comming it in my big tank. I had already put out my Aimara for sale, he and the red kaloi is not exactly friendly anyway.

My observation also tells me it is not cause by glass reflection, as you can see from the video when he is swimming the corner of his eyes catches his own tail and he treats that as another fish and attack it as if its another fish. 

For those that is acquiring a new fish observe the tail, if they're tattered and torn then it is a possible tail biter. Its not a total lost fish if you're planning to comm it, but keeping it in solitary tank will be most disappointing.

*update I've tried experimenting with high flow rate and 3 days later the fish is still chasing his own tail. So high flow rate didnt work in my experiment.

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

Tanning Marulioides

Another way you can bloom the flower of your marulioides is with the tanning technique. First lets understand a little bit about the flower. The flower is actually a dead pixel, marulioides are very unique fish, they possessed the ability to change color at will like a chameleon. But when the flower is formed that scale is spoiled and no longer changes color, it cannot get darker or lighter. As mentioned many times marulioides caught in river or big water always shows minimal flower, maru caught in dead water like peat swamp shows maximum flowers. Maru would need the color changing ability to survive, they can change color to hunt and to escape from predators. Meanwhile maru living in black dead water swamp do not need the color changing ability as much or maybe the low PH somehow destroy the color changing ability and the result will be plentiful of flowers or plenty of spoiled scale. I've done experiment on maru living in fast cycled tank and they lose the flowers or in ano

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
