After the change to coco-fiber from foam for most of my pacman frogs, in checking on them a little while ago all -- except the smallest/youngest three -- seem to be bloated some. They are all a bit puffy.

Why would this happen? Stress from the change? Should I give it a few days before I worry about it?

I use Repti-Safe treated water for expanding the substrate as I usually do.

I'll take a couple of pictures and post them soon.
