The other day I fed my fish some orange and nothing after. You know orange looks the same coming out so there was no denying the poop that followed was orange but then later that evening my girl started pooping this very rigid somewhat thinner brown poop. It looked like the driftwood in her tank.

Do you think this could be harmful? I would hate to lose a fish to intestinal splinters or something strange like that.
I always said goldfish are anythingthatstopsmovingivores but this is ridiculous!
