Well today i was spot checking the tank and one of my frogs began to defecate. So right after he was done, i picked up his poop and I seen something hanging(not that i dissect poop), which was a worm i fed him the night before. IT was a red wigglers and i was wondering if it's normal for my frog to have eaten a worm and it came out looking exactly the same. Is this a digestion problem? Or is this normal?
