Chocoalte Cichlid shock?

[Sizzy905]

I had a chocolate cichlid with a pair of blood parrots, green Severum, and one electric blue acara in a 75 gallon. Everything was okay until the parrot cichlids started laying eggs and became very aggressive towards the chocolate cichlid which is at the bottom of the food chain in my tank. It was beat on a lot and had many bruises so I had no choice but to move it to an empty 20 long I have. Now it was fine in the bucket during the move, but the moment I put it in to the 20 gallon (btw brought water from the 75 gallon, so it’s not a matter of water parameters I think) the cichlid developed light patches on the outer parts of its body. I did a 50% wc and added two table spoons of aquarium salt.
Can any one help? It it due to shock? Or is it because the Cichlid is trying to adapt?
PS third pic is before the move.

It's just stressed out being in a new environment

Thanks yeah that’s what I thought hope it’s nothing more than that though.

I had a chocolate cichlid who was really badly beaten up but I put him in a hospital tank and he lauded on his side for days but after a week he started to swim about again but I put him back in the tank and he got beat up again so I had to remove the aggresive fish, I think you’ll either have to sell yours or sell the blood parrots
