Bought my first tank, a 29g, when I was 19 and despite knowing absolutely nothing about the hobby up until the last month (and I still have a looooooong way to go) have managed to keep my original 2 Blackskirt Tetras alive that entire time, even on a 900 mile move from Wisconsin to Alabama (unfortunately they are the only 2).
I bought a second 29g about 9 months ago and a 20g and a 10g in the last month. Hoping to have all of my fish last as long as my first 2 now.
