looks like an old european cityscape, maybe even middle eastern? you can definately make out the bridge and some sort of waterwheel above and to the left of that, its neat but personally i think its really tacky, maybe has more meaning if your from that place.
wait, what the heck is going on with the shape of the glass/acrylic on the side is it a ramp?
I saw this thing at Able Auctions maybe 5 or 6 years ago, it was a tank that was in a restaurant that had closed. At that time it had little figurines glued to it, it was oriental themed with pagodas, fishermen etc.. even had a little water wheel that had a pump running up to it to make it turn.It had a couple of plant in it as well. It was gaudy as all hell then and in my opinion still is, even without the extra ornaments.
