Yeah, blue hippo tang.
Wow, wouldn't they end up pooping the poop that they eat? It almost sounds like the process of pooping ingested poop would like blow a hole in the universe like the time-space continuum.
Thanks. If that's the case, I won't worry about parasites or anthing like that. It's just gross sometimes. He moves around, then he stops dead by the rock. No expression or movement whatsoever. Then poop starts sliding out of him, then he eagerly eats it. Yuck.
