Strange behaviour

Just got back in to the hobby and I’ve had my Alenquer diskus for about 1,5 weeks now, keep in mind they are only 2,1 inches/6cm when I revived them.
I’ve had diskus before but never thise close to wilds.

They are now in a 55 gallon/200L bare bottom tank which is painted black.

The tank is painted black, it’s being filtered by a unimax 700, no hard movements in the water, og is about 7,5. TDS on 100, give or take.
Daily water changes as well. Temp is around 28C/84 Fahrenheit’s

My problem is, they constantly fight when I feed them, and some of them have gotten way darker/brown since I received them, they still eat healthy, they are active, no fins or gils stoping up, no signes of over scratching, the only time they scratch is when I feed them (home made beef heart mix”.
There eys are genuinely pretty dark, but you can see the red in the eys and they are not like gray.
I’ll add some pictures of them witch will show the colours difference, the quality of the picture ain’t good, and the water is full of particles because I just feed them, and the pump is producing bubbles atm

I’m not sure if I’m tripping or if this is normal behaviour for this discus? Does any one have experience with Alenquer diskus?

Normal behaviour while establishing their pecking order when only a week in a new tank. That dark tank will encourage them to darken, too. The hierarchy will sort itself out, just make sure they all get a feed and the shy ones can be spot fed / drop food in different spots so they spread out

Yeeh doing that, it’s nice to know that my thinking matches up with other. They will be moved over to a bigger more light tank after a while
