I'm like Tricksterpup, and use up to four 35 gal Rubbermaid (circular) tubs in my back yard. Mine are solid blue colored, and don't allow light in the sides. I had Flagfish and Bettas in them. The Flagfish bred! I live in Georgia and get quite a bit of heat and rain during the summer. I left my fish outdoors till the temps started dropping below the 60's. Probably should have done it sooner, but they were fine. The temps get over 100 degrees in the shade here in the summer, too! I used submerged and floating plants in my setups. It could be interesting to try breeding Neons this way! The water naturally drops pH with rainfall and if high light causes much algae, then GREAT, now it's dark enough for them to breed! I believe this helped keep some of my FFF fry alive! Plants I used outdoors for about 4-5 months include Ludwigia, Ambulia, Crypts (various), Quadrafolia, Rotalla Indica, and of coarse Java Fern and Moss!
For indoor use (which isn't a problem, except generally higher evaporation) I'd stick with Bettas (or smallish anabantoids) or top dwelling fish. Mainly this is just to see your fish occasionally! I'd also use a airstone and a small submersible heater. I'd just set it in a well lit area in the house and not worry about adding individual light (which would tend to make it visually unpleasing). You will also have to feed sparingly in this type tank.
These can be easily used for utility perposes (breeding, grow-out, plant-propigation, etc.) and if you take your time can be visually pleasing also!
