a flowerhorn would have to be smaller but i think its not a good idea unless the oscar has room to run any of the other 2 might work better i had an oscar with a flowerhorn once and had to take the flowerhorn out cause it was going to kill the oscar
Could you give us more info as to what tank size, what is the size of the oscar, and what size is the fish your going to get. In most cases the oscar will get his *** kicked. The 3 fish you listed are insanely aggressive compared to an oscar...
