I just adopted a 4 year old female Beardy and moved her into a new tank. She's eating a lot but she just made very smelly diarrhea and she's turned black.

This only happened 20 minutes ago and I'm a new owner with little experience. She's in a new cage on newspaper, eating many crickets and veggies. Her poop 3 days ago was healthy but just now it was wet and very stinky but not too liquid.

I'll keep an eye on her since it may be stress and she is eating, but I'm already nervous if she gets sick.

The diarrhea seems to be gone but she seems very irritable. I can't put my hand in the cage without her turning black and looking upset. She's normally very nice and docile. I wonder what could be upsetting her?
