need help with cloudy water

[Race2d]

I have a 55 gallon African cichlid tank the other day I added one fish to the tank that was smaller then the rest and i noticed the next day the fish was getting beat up so i took him out and after that I noticed the water got really cloudy because I also did a 25% water change the tank is cycled and all my readings are were need to be I have two filters on this tank with about 800 gph so what is cause this cloudiness?

hmmm, don't know about the cloudiness, but next time make sure to completely rearrange the decorations in the tank so the established territories get removed. That should keep the new fish from being beat up, hopefully.
