I have a few tanks laying around. So i disassembled a 10gallon for the glass. Then i grabbed a 20gal and cleaned it all out. I cut a piece of glass about 5" high and siliconed it in the 20gal tank to make a divider. Its placed so I can fill one side of the tank about 4.5" high with water and the other side will be dirt. The water side takes up 65% of the footprint. I am thinking of some small plants on the dirt side, and some p gravel on the water side. But not sure on what animal i should put in there. Was thinking crabs or something.
I am at a loss of ideas, so if anyone has a tank similar, let me know what you got in there, this was a total impulse thing. I am planning on heating the water and filtering it of course. It will have to be small of course too because of the tank size, if this works out good, I may turn a 55gal into the same setup.
pics will come tomorrow, because i didnt have my cam with me.
