Seems 9 out of 10 regurge cases are end up as "i took a stool sample to the vet and he has parasites."
The good news is that parasites are pretty easy to get rid of via meds. A lot easier than getting rid of mites for example. If I were you, I would wait one normal interval to feed again (like if you feed every sunday, wait until next sunday to feed again.) Fix your temp situation and try again. If you get another regurge, you'll know its most likely parasites and you can make a trip to the vet. Good luck!
