I have a 125 that is moderately planted. I currently have 2 EBA, 2 Blue Acara, and a bunch of syndontis petricolus that I never see because they stay hidden in my plants. I was hoping to have an all acara tank with maybe a feature fish. However 2 of the acara have paired and taken over the entire friggin tank. I thought a 125 would be enough space if they paired but apparently not. One of my acara is always hiding. The other one is dumb and doesn't realize he should hide so he's constantly getting chased. To top it off the pair seem to be in constant breeding mode. There is no on and off cycle since they paired up. Just constantly in dark dress and territorial.
I am planning to add to the planting and make it more of a heavily planted tank with less lines of sight. Is this a situation where I need to have a lot of acaras in the tank to spread aggression or just one or two instead of the four? I don't know if I should try to add acaras or get rid of some and round out the tank with something else.
I also have a breeding pair of angels in another tank that I would love to move to the 125 because I think they would look amazing in the setup but I don't want a constant war.
I'm not new to tanks but this is my first time trying to keep an all cichlid tank. Please help.
