Why would cichla sudenly get agresive with there tank mate more info below

[WckedMidas]

Ok ive had two cichla for awhile now maybe 6 months or so. Just got back from florida brought two more cichla back that i ended up catching down in florida. Now my original two always got alone never had a issue with them. Now the two new larger cichla are in the tank . One of my original two has decided he wants to hang with the big boys. and keeps flairing up and chaseing his original tank mate.

probably fighting over territory, trying to assert dominance in the tank. How big is the tank?

There doesn't look like much water in the tank with a lot of bits in there. Too cramped

 

[WckedMidas]

its close to 150 gallons in the bottom. if u notice in the first pic it has a deep end and a shallow end.

the rock caves arent in there anymore either there older pics

Seems like a weird setup. Maybe the fish are just confused.

This is your best answer.

i understand the dominance thing. but why would one of the original two decide to group with the two new larger ones only one is geting punked. Also all there markings have goten alot bolder since the new ones. maybe it is just a dominance thing. just didnt see one geting singled out figured the two little ones would have both been punked if they didnt get along. not just one.
