Here's something similar to that. I had a 6" flowerhorn and a 6" motoguense. They fought for more than half an hour. It would have went on longer if I didn't separate them. The flowerhorn won the fight by my decision because he got the better bites. The next day I took out the separator and the flowerhorn got scared. It was a great fight. But I had to stop it because I had to go to sleep for work. I thought they would still fight again, but I was wrong. Wish I would've let them fight till they end it themselves. They were both still wanting to fight when I separated them.
But anyways. I say the managuense will win. Why? It's got bigger mouth. And I think it's a tougher fish in general. Unless you got a mean red devil and a not so mean jaguar.
yah, here's an answer. what a dumb way to keep fish ! why keep fish in the first place if your primary interest is letting them fight to the death just to see which fish would win. who gives a rats *** which fish would win. you have the intellect of people that fight dogs and chickens. it's simply ignorant.
If you were doing this with dogs, you would be reported to Animal Control and the Police, and would have your pets taken away from you. This is not a responsible way to approach the care of any animals entrusted to your care.
Because this is a site dedicated to the CARE of fish, not their abuse, this discussion is ended.
