Yeah basicly it would be just a large clear tube thats about 5 feet round, and about 7 feet long, with a heavy cement base. Look at it like a "human tank" for your fish. Instead of vice a versa. I was then thinking about installing a dock over the top of it. You walk out on the dock...open up the latch, crawl down into your human tank. The dock would disguise it, it would keep the rain out, and it would be easier to crawl in and out of it.

I just got a find a guy that can build a tube...but dont know where to look?
