6g Stocking?

[Michaelbknudsen]

I am curious as to what some options may be for fish/inverts in my 6g nano cube. I was considering a pistol shrimp/ywg combo, but kinda fall short on ideas after that. I have a red hermit and turbo snail in there now with a frogspawn and evergreen star polyp.

Might be a bit expensive but a flaming prawn goby? They get to about one inch I was looking to buy one but can't find any in Australia
