I had a small 5 gallon tank and 1.5 gallon isolation tank for a few years. Live plants, a couple guppies, a few ghost shrimp, and an Otocinclus Catfish.
I enjoyed it while I had it, but eventually the fish died off, and I threw in the towel.
I couldn't seem to find some of the later photos, but this was when it was just getting started. I did remove the soda can after a while, lol
