First, I'd like to apologize ahead of time if I'm just being paranoid! But, its better to be safe and ask, then regret it later, so here it goes..
I noticed after Norbert's last shed he now has very light yellow spots on his abdomen. They're pretty evenly spaced and seem to be just a pattern he has. After reading some info on yellow fungus, however, it made me nervous. I couldn't find any pictures that look exactly like what he has, so I don't really think he has it...but I just wanted to get some reassurance. I took a few pictures to show you what I mean.
Any thoughts? Besides the color the scales look no different from the white ones.
It looks like pattern. I've seen many yellow belly beardies... on some high color citrus dragons, there can be quite a bit of it. Some dragons have what looks like a " cheetah" or leopard pattern, with the color primarily in the rosettes [ in the stress circles ]
No, they don't all have perfectly white bellies. It appears yours has a nice yellow pattern starting, it is beautiful.
It doesn't really look like yellow fungus, thankfully!
