Definitely a male. Most likely johanna. The fish is simply in a mood where its patterning is represented by the main body stripe fading out. I suspect that at times the fish exhibits the typical, wide body stripe that helps to identify johanna.
Definitely looks stressed so I agree the patterning is gone. Dont know what type of fish it is though, Scat is better at ID'ing pikes then most so i'd have to go with what he says.
