Obviously Kratos is new to cichlid keeping. I think what set you guys off is that he said 'lets take bets to see who's going to die'. But then he said he was just kidding around. Let's forget he said that and give him a break. Remember when we were new? We didn't know sh*t from shinola on what was compatible with what or even understand the concept of how few cichlids you can keep in a tank. Most of us long timers learned by trial and error. At least he has an opportunity to learn from our experience...now if he keeps up the B.S., that's a different story.
Kratos, apparently you have a 65 gallon tank. I know you don't want to hear this but in the near future, that tank will only be large enough to house either 1 Oscar OR 1 Red Devil OR 1 Trimac (Flowerhorn in your case). I know it sucks but that's the short end of the stick my friend. If you want to keep multiple fish, you could keep the EBJD and a couple of other less agressive and smaller growing cichlids or other type of fish like some Silver Dollars or other dithers.
Good Luck in your new hobby.
