Due to me disposing of my marine tank, now I have this idea for the next fresh water setup.

I have this IKEA coffee table (tabletop size 1250x700mm) but it is low (coffee table height). I also have 3 sets of 2ft fishtank.

I intend to put all 3 of the 2ft fish tank side by side on this IKEA tabletop.
I intend to have this natural, no pump, no filter, no lights, just plants and guppies or barbs to prevent mosquitos. This setup is next to my balcony so it gets filtered daylight. I can put some lights to light up for the evening so that can have better viewing. I can have a vivarium type setup or just a "pond" type setup.

So any idea of plants or drift wood setup? Any suggestions?
