I dunno if you seen them or not yet.
But I have a buddy of mine that wons Fishy Business down in Bolwing Gree, Ky.
He is the one who makes the rotating aquariums.
Kinda neat.
He's the first one ever to make one that does rotae where you can see all sides of the tank.
Also, the first ever in the US to successfully breed organge brittle stars and been featured twice on Aqurium magazine.
I'm building him a website if he ever gets the rest of the photos for me to finish his site. I'm doing it in exchange for products.
If you never seen a rotating tank.
Here is the link for it off my design site.
