Is this velvet?
Noticed this grey area on one side of my tetra a few weeks ago. The fish appears otherwise healthy and normal, no other fish have any such marks. The discoloration has now spread to both sides of his dorsal fin. I haven't treated him because I wanted to be sure I was treating for the correct disease and this didnt look like any pictures I could find online. Is it velvet or something else?
Any help or guidance gratefully received.
Regardless, get it out and isolate it just in case. I would also do a huge water change and check your other fish over too.

With all the room and tank lights off, turn a flashlight on that fish tonight and you'll know if it's velvet or not. Velvet is a parasite. Very contagious to all inhabitants so check all your fish. You will probably have to treat the whole tank.
I'll know that its velvet because it looks like what under a flashlight?

The light will shine back at you gold. The fish "shimmer" or "shine" in the areas where velvet attaches. Some people say it looks like "gold dust".
Behind the gills and below the dorsal fin are where you see them.
Sounds more like NTD to me, but either way I would isolate the fish.
NTD or columnaris
After careful inspection under good light in a specimen container i see that the poor fellow has lost most of one of his gill covers also. I gave him a meth blue/salt bath. After the bath the diseased area did not retain any blue as I was led to believe would happen with columnaris. So with a new an improved photo, any guesses to NTD or columnaris or even something else?
It doesnt look like columnaris or velvet in the better picture to me. Im thinking NTD
