I agree with Stefan on the I.D. T. elegans vagrans not T. sirtalis.
I too think you dodged a bullet on the brumation.
Brumation is a tricky situation to say the least and a snake wouldn't have brumated itself that way.

Parasites are very likely in a wild caught snake and getting the dose right is very important. What are you planning on treating with (only after a positive I.D. on the parasite/s) ?
Looks like minnow in that bowl. Best to get her off them if you want to stay away from parasites and thiaminase issues.

Nice to see you back.
