I found this neat setup at http:\\www.rva.ne.jp/gallery/of_e.html This page is a translation from Japanese, so keep that in mind while reading. Anyway, it looks like a good setup for breeders, and I thought some of you might be interested. It has the footprint of a 20-high (24 inches long), but obviously much taller. The top tanks are only a couple of gallons per 'room' which would be good for fry and such. I have emailed them about estimated shipping costs to US and will post when received.
