A few more names for him/her it may be a hybrid those dark stripes/bars make me think of a shell cracker ( a really large bream ) most times when I write bream I am referring to a bluegill kina depends on who I am talking to . When speaking to my Yankee inlaws I speak yankee LOL
I was thinking the same thing right when I seen the first pics before seeing these people say it. I think the spelling of this fish is wrong but it is what I was thinking.
Thats why I was having a hard time... I still think its a green fish... and thought it looked cichlid too, but couldn't find any that matched that fish in particular...... It could be that it's color is washed out from stress from it's new environment.... seeing you all the time, the other fish etc.
The tank is a nice set up but I wouldn't add anymore fish than what you have with that size tank.
