looking for TALL artificial tree sponge

[CTaylor]

Hi,
I found one that is 17" tall.
http://www.fishtanksdirect.com/ocean...ica-12-rr.aspx << that one also has no base.

But my tank is 24". So, being picky, I'd prefer one about 20" tall. I had a perfect one several years ago before I had to take the tank down for a few years and it ended up breaking. It was about 22" I think, and had a nice heavy base.

Anyone know where to look?

Thanks!
