Rosie's can go awhile without eating so like you mentioned nothing to worry to much about. When I got my first rose hair she went months without eating.

What are you currently using as substrate? Sometimes when they start wandering around it's because they don't like the substrate. Which could be a few things like it being to damp, using bark chips, and even the floor being a bit hot from a heating pad underneath.

If you think it could be from dampness try letting the substrate dry out a bit and just provide a little water dish. If you are using bark chips you should try and get rid of that right away as bark chips can cause possible future problems outside of just discomfort for your T.

In regards to the possibility of a heating pad making the ground too warm, I would also get rid of that as long as your house doesn't get real cold. Heating pads can lead to different issues as well and as long as your comfortable she should be comfortable.

The Avicularia versicolor (Martinique or Antilles Pink Toe) is readily identifiable against the much more common Avicularia avicularia (Common Pink Toe). The former is bright metallic blue as a s'ling and juvenile until it reaches maturity and takes on a dramatic change in appearance - from blue to a striking abdomen covered in red setae, and both the carapace and legs will have a green to dark bluish sheen to them. The Avic avic on the other hand is what you will find most commonly at the local pet store, and is almost entirely black with the pink scopulae at the end of each leg.

I hope that makes it's almost 1:30 am here I'm starting to really feel it, lol
