I guess in the end, the biotope will have only the Gachua
In my observation all the fishes with thinner body like bimacs, killies, zebra danios etc are more likely to become prey compared to something like a Rosy Barb which wont easily fit into the predator's mouth.

Nayak, you are either spending too much time in the fish room which would be obvious or the fishes are timing themselves to give you a spectacle......none of this stuff happens in front of me with my fishes.....let alone me taking pictures of them.....

Could end up as a Gachua only tank. Maybe you should take him and put him in a separate tank.
Then introduce a same size to size tilapia. or an African cat fish. And specialize in 'predator in action' photography.

The Gachua I have gobbles up a tilapia every other day and takes a revenge from the tilapia community for taking over its habitat!

Nope, They dont bother larger Puntis species like the Rosies. MY channa gachua have grown quite a bit since i got them last month. They leave all the larger bodied fish alone. The slender bodied fish are fair game. The only exception i have seen are loaches that seem ablivious to the snake heads. Neither bothers the other.

And gosh its fun to watch a one sided fight
Its not the Tilapia's fault. It was invited and introduced by the the Govt. as a food fish into our native fresh waters.

Its our own fault then! I believe they had good intentions when they did it, but everything went so wrong. One question remains though - was it a case of bad research or plain bad luck.

Tilapia was introduced to provide a easily available source of protein to our population.
It has succeeded in that respect. Even today rural folk harvest the fish on a daily basis to
include in their cooking, free of charge.
To a large extent this has happened to the detriment of the endemic fish population, but has benefited humans,
many in the FAO will argue against the bad effects, especially the people who recommended the Tilapia introduction. :D

Very true, Siddarth and Preetham. In my Biotope the only fish unmolested by the gachua was the L.thermalis.
Wow Nayak, Predator vs Prey pics are really cool.
Was that a first kill for this Gachua?
Nope, Yogesh. I have lost two A.lineatus, one R.daniconius and one P. bimaculatus. But the killings had stoped for a long time after I started feeding frozen Artemia and blood worms. Guess the hunting instinct is too strong.

Already separated, trevor. And it is a "her". Only a female of any species can be sooo mean
