I've never had a fish with fin rot (that I know of) and someone pointed out that Murphy may have fin rot
He's got black on the tips of his fins but no damage. His fins aren't torn or ripped looking.
Does it look like his natural color? Or does it look like it may be fin rot? And will it hurt him if I treat him and he doesn't have fin rot?
I'm sorry for the sub-par pics...I really have a hard time taking a pic of him.
And a silouette of his caudal fin...

The test thing I did was Ammonia/NH3/NH4. None of my other tanks have a reading...just this one.
I almost grabbed it, too.
