What is the largest fish you had in a nano tank?

[Gumbies R Us]

I love my nano tank. Perfect size for what I need it for, able to maintain it pretty easily and still have cool fish in it. I'm curious to know what is the largest fish you have had in your nano tank and how did it go for you?

I had a nano with a foxface, yellow tang, and a nasso tang. This is totally a real story.
