What is your smallest aquarium?

[Tinnerito]

What's the smallest aquarium you have or have ever had? How old is it? And how small?

For me, it'd be my 1 year old 7 ounce freshwater system which was just a small pen holder initially, and now I have some trumpet snails, ramshorn snails, plants, and a shrimp.

Great idea for a thread! I am quite certain that for me, it was my 1 gallon total water volume triple reef vase.. It was a tad over a year old, with bi weekly 50% water changes. Had to take it down, due to the LFS moving. I've tried smaller, but only for a month or two, here and there. Heating / cooling / evaporation for mini reefs is tough. I have, however, kept a nano freshwater planted 20 ounce for a few years. It was a no tech, white cloud minnow dish. Fun stuff.

Stunning setups!! If only I could keep saltwater aquaria in tanks that size. :grinning-face-with-sweat:
