I can tell you about my experiance with a flowerhorn, bought one at a LFS on impulse because it was cool looking and colorful. Had it with convicts and firemouths. It was fine for months, but it grew much quicker than the other fish and started slowly picking them off. I posted it on facebook to give it away and found there is a whole culture of people into them, had multible people that wanted it. They are cool looking but I wouldnt get another.
