New and need help!!

Hi Everyone! I have a 75g tank of South American Cichilids. I have 7 green terrors and one Jack Dempsey. They have always been brightly colored, active and they rarely fight.

Yesterday, I lost power for 17 hours before I was able to fix generator. the tank had just been cleaned but lost temp (it was down to 72 degrees F). The water had some waste and the fish were sluggish and lacking in color.

I noticed a cotton white fungus on one of my green terrors and what looked like bite marks. How do I treat this?

Ooof. Looks like the parameters may have swung a little to hard. Get a good wc in and keep an eye on them. Are they eating? In the future, you can/should dose prime in that situation, it will keep water detoxed for a day or two if need be.
