my midas was a mean pecker, he made my male devil try to fly out of the tank constantly hehe but then again my lil female beats him time to time also. I got a Dovii pair and the male is starting to get pretty agressive 
piranha45 said:dovii are definitely capable, but I definitely wouldn't count out B. microlepis or Cichla temensis.... I hear temensis can ram other fish like a freight train.
but if we're going ounce-for-ounce killing potential, T. dhonti, M. chipokae, and H. fasciatus are prolly top dogs from what I've heard.
CentralMayhem said:fasciatus get large enough to demolish any salvini ever to swim in water. not that they are that aggressive, but size wise they get BIG. elongatus are meaner but smaller. dovii rules hands down. ive had mean ass devils and midas', but even the 16 to 20" devils and midas' they had at steinhart aquarium were no match for a full sized male dovii. they have the size and dentition to destroy **** quickly. devils and midas get mean at a younger smaller age. you take a mature dominant dovii and a mature dominant devil/midas, and it would be an embarrasement to devil/midas fans. of wich i am one myself. but be honest look at that bastards teeth. add some size and aggression to that and you got a bad ass muthafuka.
