Just thought I'd share a pic of my 8x2x3 tank. I bought it 3 years ago and couldn't set up it for awhile due to not having enough room. I found it for $350 so I had to jump on it. I got it set up and somewhat scaped 6 months ago. I still have some nice driftwood being prepped to go in so I'll share updates soon. Currently it has 10 minnows in it. School starts up soon so when I find time I will collect some fish for it. For plumbing I found a 3000 gph on amazon for $90 that has exceeded my expectations. It's hooked up to a diy trickle tower.
