I'm also curious if you given any thought to the possible problems with having swimming critters in such a tank. Is there something to block them from moving into the area underneath - I'm really thinking of animals that might have trouble getting out, like hermit crabs and the such. This type of tank sounds very interesting.

Well I'm debating whether to tap it into my 120g or not. I said on an earlier post I'd like it separate, but if I did tap it in, it would be easier to maintain.

As for how I would tap it in, I would just drill a hole on the back pane at the top center, put in a gasket and a 90 degree bend and a stand pipe. The return from the sump would tap in at the bottom center. This would promote even further the flow from the bottom to the top, and it would just follow the flow the powerheads are pushing.

I already have an RS135 in the sump of my 120, and another 15 gallons of livestock would make not much of an addition, especially considering my 120g currently is quite understocked.

I would probably separate the sides of the display area using simple egg crate. I don't know if I'd have hermit crabs in there. Possibly emerald crabs, which can't make it through the egg crate. No clue what kind of fish would be in there really, though. Don't think any I get would make it through egg crate.
