Robert, I know you are from Ohio and I have actually spoken to a couple vets that offer endoscope in the akron area and it was very expensive. I have a group of 6 rio's, 4 of which I will be cycling shortly. None the sex gender is 100% known. They were all bought as probables, but we all know how that goes...lol. Mathamaticly speaking I'm confident. The price that was quoted to me by vets were around $300-$400 per lizard! Any info on a vet in northern or central ohio that offers endoscope reasonable would be appreciated.....A group price would be nice. Thx.
