Just an update -

I decided to go ahead and rinse the entire body with saline, especially flushing a scratch and puncture on the head that are most obvious. During the process, the little one bit me twice, which I'm taking as a good sign. I'm glad he/she is still feeling good enough to fight back. It also was eye licking, and still moving around actively. *crosses fingers*

I don't know what else to do, so I'm just keeping the tank heavily misted and warm, with only silk plants to prevent any irritation. I guess I'll just wait and see.
