I've seen him hunting quite often and he's pretty accurate, so he doesn't end up eating very much of that. Plus, coco-fiber isn't supposed to cause impaction.

I don't think it could be malnourishment though, because he's pretty fat, even after pooping and peeing. I think certain frogs are probably just more prone to it than others.
They never said that coco fiber doesn't cause impaction or constipation. Its just easier to pass and less likely tp cause such ailments in your frogs. Temps and moisture levels have a lot to do with their digestion. They need heat to properly digest and metabolize their food. Spacing out meals helps to prevent such large poops that take longer to pass.
