Early this morning I noticed that my betta fish had a grey streak going across the side of his body that was not there before. My fish was also laying on the bottom of the tank at one point breathing very heavily. From research I have done it looks like it could possibly be graphite but I am not 100% sure. I just wanted a second opinion on what this could possibly be and how to treat it! Thank you for your help! (i’ve attached an image below)View attachment 168325
This is the first time I have heard velvet (Oodinium) called graphite .I had to look it up.

It's an odd marking. I would watch it. If it is something other than a problem with the chromatophores (the colour cells) it'll manifest itself quickly. It could be an infection under the skin. It is not like Oodinium to me, a parasite I have dealt with often in my softwater tanks.

Watch wait and worry if you are so inclined. It could well be nothing, and you can't treat it with no diagnosis. Shotgunning meds is harmful.

And hello from the Fundy coast!
