I hear ya, and it will be a question that goes on for awhile.

Until there is some stability it will never level out.

Hey you never commented on my niles below, I figured you might like them. New yellow species haha (Joking)

But I never would of picked the rescued female left in a box at my doorstep to grow into such a beautiful animal. The male was also a rescue given to a friend of mine who in turn passe him down to me. Funny niether were yellow until I got them. Both started gray/white/black. Must be all the yolk in the chicks they eat seeping through the skin haha. Or maybe since the female was yellow first the male just liked the color?
