I ask how to see the gonad ready or not, i can lowering temporary tht temperature, maybe 3 month i can, but how to see my channa rede or not?Have they had fry before and you can't get them to breed again?
It might help to lower the water temperature to 15°c for a few months to trigger breeding.
If i see tht video, my belly fish like this, but how about tht male,? Or other way to see mature gonad? Maybe like a catfish can be see on tht reproduction organI don't think you can see any reproductive organs, only mating rituals.
The females belly should be visibly larger with eggs.
Here's a video I found on YouTube of spawning.
As they get nearer spawning, they will practice the moves with each other
