Right now I only have a 5 gal nano up and running for about a month now. I have some green/purple mushrooms, white/orange button polyps, 3 turbo snails, 3 hermits, an emerald crab, and one green Chromi. I had two but the other one got sucked up in my powerhead I think. Equipment wise I have an Eheim Liberty 100 filter, some little powerhead(will replace with a coralia soon), heater, and a 12" Current PC 50/50 light with lunar LED.
