You added these fish after fully cycled?
The fish that you added- which groups at which time? How long ago?

There were no ammonia or nitrIte readings at any time after adding fish?

How many water changes and volume of water changes since tank established with no ammonia or nitrates- but nitrAte reading?

Any aggression between fish?
It looks to me like the dorsal is completely gone ? Fin rot of that extent takes longer than overnight.

Is the fish eating?
