More black fish!! NOT amonia

[Candi1990]

Please help fast! Had a very sick tank. Starting to get levels right, was advised to cycle with fish.

.Getting the levels right in the tank.... So i was advised that the tank was well enough to do a fish in cycle. Ph 7.6 ammonia back down to 0 nitrites .25 (i think very low almost yellow dont have number in front of me) Nitrates high but down to 80 (was 160). 55 gal tank.

Went and bought beautiful fish, turned black immediately!! WTH!!!! Within 10 min! Not Ammonia burns no ammonia! What now???? I want to save my new fish!

The one at the bottom behind the rock was a fleshy colored fish!!

I moved them to a good tank... All the previous fish that was in there are fine, but they are getting blacker!!!
