Thanks. I'm not sure if loose substrate should be considered a big risk when putting loose crickets in for food... he did eat without complaint today, thought.

Could it just be water weight? He seems to behave alright other than the bloat, which I should probably mention seems to flare back up a day or so after he pees both times I thought it would be a long term improvement, but it seems he'll just swell right back up
