Scoly Mouth Darkening

[Markxc]

hi all - I've had this scoly for about two months now and since i got it, the area around the mouth has darkened quite a bit. does it look like something is wrong with it?

Is it still eating and/or putting out tentacles? I do not know much about scoly's, but it looks pretty juicy still. It may be possible that it's just changing colors in your water/lights.
