Not if he's pooping. When they eat, and have a turd brewing, it gets tight in there and when yer frog passes the turd the food will naturally reposition to the center. I freaked the first time I saw it and went through all the steps (as you listed above) for a few days. He ended up pooping in his water bowl when he was ready. so no worries. As long as he's crapped recently he should be fine. Keep and eye on him (as we always should even when not worried about em).

If I'm wrong, one of the mods or forum veterans will correct as necessary.
