ok well i was doing a spot cleanning of the babies tank today and i saw a god sized poop i picked it out and saw a shiny black bit(it was fully dried so that was wierd) after further inspection i noticed that it looked like a part of an insect shell one of the parts that covers the wings i did find an eareig in the tank before so is it possible that one of the babies ate an earwig there was also smaller shiny bits that could have been the head and maybe some other parts as well
