I saw a picture of a reef aquarium with an old budweiser can on the sand. is this ok?

Not that I want to do this, but it was pretty funny to see a copper banded butterfly fish swimming around an old crunched up faded Budweiser can. It seemed to remind me of a few dives I have been on in the LA harbor.

Would an aluminum can in a small reef tank put off any bad chemical reactions or affect the animals in any way (other than making them feel like they live in a dump)?

It was PaulB's tank right? He coated it in fiberglass resin so it wouldn't rust or anything.
