While at the AE show...

We saw two 125's that had self contained filters build into the inside rear of the tanks....older tanks too....the corners were rounded instead of squared off too......They were brought in by a fellow GCCA member for the display that they had set up.....gorgeous tanks...and yes, acrylic.....

You get a front view on the right tank, and a view of the rear filtering chambers on the left tank..

We had one like that set up in a school room a couple years back. Love it.

They are unique for sure.....I'll be on the look out for them now...
