Step 7: The Finished Aquarium

And here is the finished tank, ready to add fish.

i think it can be done with an LED light on top

 I belive fish (and perhaps other aquatic animals as well, not sure) need to get the light from straight above in order to get a good sense of orientation and well being. Like stinna2 already commented, the lack of filtration will make this aquarium unhealthy in a short time. The plants will provide oxygen, but the water still needs to be stirred or else there will be a layer of proteins and other dirt on th surface.
Apart from that, the tank looks really good! Maybe you could keep snails or shrimps in it, that way you wouldn't need to worry about the size of it being to small for the fish. but some guppys would prbably do just fine in there too.
Good luck!

The tank has an undergravel filter. I cut a couple up and glued them back together to make a filter plate that covers almost all the bottom. If you look closely in the picture above, you'll see the air tube on the opposite side of the light tube. The air hose goes down the light tube.

I really don't think the fish care where the light is coming from.

Oh, sorry about that. Sounds great.
I really don't wanna come off as a "miss-know-it-all", but i'm pretty sure that my statement about the lighting is atleast somewhat accurate. in nature, the sun is always above the water, shining down. Most fish are coloured so that their underside is lighter (to blend with the light from above) than their oversides (to blend with the darknes from below). Plants should probably benefit most from aboveside lighting as well, or else they may become crooked. But your plants look relly godd and healthy, so maybe i'm wrong about that one.
Anyhow, I really don't hink that it's VITAL for the fishies survival or anything. :)
I have lights on the side of one of my tanks as well.
I think we have the same fish...platys?
Cheers

No problems. I don't claim to be an expert on fish (or anything else really). I need to add a bunch more details to this instructable and will in the next day or two.

i just noticed your build.  Very nice!!  i am just wondering about filtration...
