The above is what most do when you need a pair among channas, when they're not sexually dimorphic.It is really hard to sex this species so i dont wanna have a go on it. But my guess is a female but dont take me on my words on that as im not 100% sure. If you wanna find a mate to it all i can say is good luck since they are very agressive to other fish of the same species. I you want a pair you should buy a small group of lets say 8 individuals and let them pair up to one pair then sell the rest. Thats your best shot IMO.
Channa can't be paired like cichlids, that is, keep a divider and then introduce them and hope for the best.thank you for the quick response. so i got her (my gut tells me it’s a she) back in March and now it has grown to about slightly more then a foot long.
would pairing be risky? do i need to get the same species and similar size to try?
worried they get too aggressive when i introduce the new mate into the tank
