These green marks appeared a while back on his lips. They have spread over time and are a greenish/brown in color. They are not raised or fuzzy or anything. It appears like just his coloring in his scales is changed in those places. It almost looks like algae... i know thats retarded, but thats just what it looks like. The green is almost irridescent.

Is this a disease? Do pikes get this, because none of my other fish have anything like it.

Tank is 125 g.
3 Fluval 404 are running on it.
Last w/c was a week ago.
Params are Nitrite- 0, Nitrate-20, Ammonia- 0

No other signs or symptoms

(the crescent shaped injury on his operculum is from a bite)

I had this in the Pike section with no luck, so i'm trying it here although i dont know that it is even a health issue or not.

Well, Peanut Power wins again. He is the Pike god. Told me its a rare condition, no known cause or cure. (there are theories- parasites/fungus/bacteria) Pikes that have it are known as "Manchada Pikes." just FYI in case anyone looked and was wondering what it was also. So i dont know how he got it, but he's doing fine, so i wont worry since i have no information on how to get rid of it. Just make him have a good life.

Thanks Peanut!
