Killer Dragonfish?

I'm surprised your goby doesn't see them as appetizers. Anyway, it's basically an open bottom system like this, http://www.youtube.com/watch?v=C2EIO2hX1Hc&feature=fvsr, with a small hole and a good bit of land for the crabs. I used a 5g hex on top of a 29g for my fiddlers, worked like a charm. An air pump is housed in a false top of the inverted tank, and tubing is run from an airtight hole in the top (really the bottom) of the small tank to the lower tank, creating a siphon. When the water level is good, the end of the air tubing is attached to an airstone and positioned so it bubbles into the smaller tank. Sounds complicated, but once it's constructed it's a piece of cake and looks completely mind-blowing.

Cool video. It does sound complicated & I am typically pretty technical minded, but I can't seem to wrap my mind around just how this thing works? I'll Google around & see if I can't find a diagram or something. Thanks,
Steve
