Hey guys. My P. friedrichstalli has started to lose some pigmentation on its face, and now its starting to lose color on top of its shoulder as well.
It is normally a very dark, vibrant green with heavy black banding (its on black sand substrate). Its lost most of the vibrant green color, and is now more of a grey tinged green color. Also the green on its face has started changing to yellow. Just today I've noticed that its starting to show white on top of its shoulders, and is swimming around with clamped fins.
This has been going on for about a week.
I did a water change on this tank on Saturday, and all the other fish are acting completely normal. He is still active and has a hearty appetite, and is still defending his "spot" against the other fish in the tank, he's just started to lose pigmentation or get stressed out or something. I've loaded some pictures so hopefully you can see what I'm talking about.
Any idea's what might be going on?
