As I go about all pictures in this site (photograph & videos), I noticed that grown up oscar have muscles in the head, just right above the eyes. There are five or six pictures on files that have contour above the eyes that looks like crown.

My oscars is now showing those curves too. My previous albino had it. I don't know if you guys had noticed it. There are normal changes as they grow up like lumps, colors, markings which are usually shows as they grows, but boulder on the head? i just noticed it.

Have you?
