Hello, one of my two clown plecos went missing for a few days, and when I finally found him, I noticed this gold dust look to his face and a bit on the fins. I don't know if it's normal, as it's the first time I have shined a flash light on the fish, and I can't really see the other clown pleco I have, because he is always in the cave he dug under some driftwood. I didn't see any dust looking stuff on the body. None of my other fish, show any signs of an illness. Have zebra danios, bluefin danios, and neon tetras in the tank.
I've had him since August, and the latest thing I added was some red cherry shrimp back in November. Water parameters are good as well. At first, I thought maybe it was velvet, but another post I read somewhere had a picture similar to what I see and they said it was normal, but I can't really find any other sources to corroborate that with.
I am having difficulty getting better pictures, as my camera doesn't want to focus properly, and I don't want to blind my fish with a bright light any more than I have to.
The second pic is blurry, but you can still make out the gold bits. It almost looks like glitter.
