Thanks for the advice. There was styrofoam on the top and bottom, but the box was an odd shape. Next time I'll be doing a box that is better suited to a single bag.
i think that bag would have fit perfectly if the styro was a little thicker and you had the bag
filled a little more with pure oxy. or just stuffed/padded more with newspaper and what not.
but hey look on the bright side; grats on your first successful shipping of live fish!
