I recently had a fish show up at a customers site in pieces. The head was broken off the body, the board I mounted on the fish to screw to the habitat base was broken in half and the foam rocks on the habitat were also broken off. Thanks USPS. Regardless, I am going to repair the damage for my customer, but I am nervous about packing up and sending out this new fish. So, what do you all use for packaging material inside the boxes. Other then crumpled up newspaper. Cheers. Chuck.
