First off sorry for the bad cell phone pics, I currently have two small royal gramma's and a small half black mimic tang in QT. Through last night all have looked great, swimming and eating fine but this morning I found one of the gramma's barely hanging on and noticed these markings where the yellow and purple meet. any help appriciated

Looks like:

Bacterial Infection: from Melypr1985

These are very common and present in many ways. They can show as dark patches, white patches, torn or tattered fins, cloudy eyes, and red streaks or sores. There are two basic types of infections and each have their own challenges. Gram positive infections can be much slower acting, but can sometimes be difficult to spot before it’s late in the infection. Gram negative infections act quickly, sometimes killing the fish within 24 hours of onset. Treatment should be done with a broad-spectrum antibiotic or combining antibiotics for the widest spectrum possible. Combining Kanaplex, Furan 2 and Metroplex has the potential for providing the widest spectrum of antibiotics for a gram negative (or even a particularly stubborn gram positive infection) and can be combine safely together.

Looks like he was attacked. Notice any aggression between the grammas?

I does look similar to one of the pics in the original post so will have to look a little more into that as there was no indication last night and dead this morning.

The one with the issue was the bigger and had chased at times the smaller smaller one but he learner real quick to hand with tang and they all got along after that.

Is this a new tank? How long have the fish been in the tank?

Still looks very like a bite to me. Bacteria would usually present as a fuzzy whitish rim or red/pink discoloration around the wound, and I'm just not seeing that here.

Thanks, Its hard to think all that was from a bite of one of these small fish but I have seen some of them in my DT yawn and mouth gets pretty big. gotta be the smaller gramma as this little tange I don't think can make his mouth that big. lol
