There seems to be a problem with our tank and fish are dying please help.

I have 9 adult lake Malawi Cichlids. I recently dropped babies. This one now has white spot on right eye. And tail is looking ratty. Another cichlid is loosing her colour and tail nearly gone. Im worried that its not a parasitic disease like ich or dropsy as i dont want the rest of my fish getting sick. I dont know how to treat the tank with health fish in there. I dont even know what to use to treat it. Im only new to cichlids and a large aquarium. I need help urgently as these fish are expensive. I cleaned tank thursday with partial water change plus cleaned both filters are they were due. These 2 fish arent looking good. - Due date: Needs to be done on Sunday, 10th Oct 2021
