Tank idea

[obscurereef]

Yes the 3 fish would have their own territories, but they are peaceful fish so it shouldn't be an issue as long as you don't overstock. The oxygen is provided by the filter and powerhead (also used for flow).

Doesn't oxygen enter the water from surface agitation? And less surface area means less oxygen? Or is sw not the same? And I have a maxi-jet 900 I can use.

I think you may only have a 13 gal tank based on the numbers.

Try the numbers to make sure

I used inside measurements and they are really 20 tall the width of a panel is 8.5 inside. The surface area is made up or 6 equal lateral triangles so it's three squares so SA=LxHx3
8.5x8.5 is 72.25 so x3 is 216.75.
Volume of prism is surface area times height
216.75x20=4335 cubic inches.
1 gallon of water is 231 cubic inches
So it is a 18.77us gallons

Also how do you measure the thickness of the glass? It doesn't come to an edge like a normal tank where you can see how thick the panes is.

That's is right though right? I don't want to stick it for 18 and then find out it is 5 short
