Well today I was spot checking my snake tanks and I was going through my corn's substrate and I thought something smelled a little rotten. I had cleaned out some poo a few days ago and thought I might have missed some. He's was on aspen bedding, so I started going through it all and I decided to check him out since he's been hiding under his water dish and sure enough there was a fuzzy under there with him. I pulled him out and put him in a little tub and cleaned out the entire tank, all the substrate included. I've got paper towels down now so I can monitor him closer. The only thing I can think of that changed was when I first moved him to fuzzy mice I slight some holes in the first one but I didn't this last feeding. He's temps are about 82-85 hot side and 70-72 cool side and the humidity is around 55%. I hope I'm right about not putting a couple holes in the fuzzy the second feeding, but back to pinkies he goes in two weeks.
