Bye Bye Harry the Potter's Angelfish

Today is a sad day; my Potter's Angelfish has passed away.  When I came to feed him this morning he was hiding still under a rock, which is very unusual because he is always constantly moving.  I moved the rock away and he was still breathing but seemed very disoriented.  I couldn't find any injuries or ailments and the water quality of my tank is fine.  I can only assume that he has died of old age.  We have had him for 4 years and I've read that the average lifespan of wild Potter's Angels is only 6.  He was one of my favorite fish I've ever had.  I will miss you Harry...

I never got a good photo of him.  He was always on the move.
