And the fools that criticised me, my objective is not to simply pit fish against each other. I like to try and see if fish are compatible with other fish, and the only way of doing that is by putting them with other fish 
When I was seeing if my wolf was capable of living with other fish, I had him with a bichir and a hujeta. When I thought my wolf was getting aggressive, I sold them both as I knew if it came to it they would not be able to defend themselves and they'd get killed easily. I didn't want that to happen.
So the only fish it's currently with are my oscars, who can defend themselves.
I also seperated my little channa from my jardini and peacock bass when it became clear they had no chance against the furious little channa.
I'm just making it clear I don't think it'd fun to pit fish against each other and kill each other, I am just testing compatibility.

You never know until you try.I once had an oscar that kept a female betta as a pet(he grew up with her)He ate feeders bigger than her every day and killed anything I put in there,but never touched the betta.
I agree...
