4 G nano

[joeyt66]

I have a little 4g tank (12x7x11 high). I set it( with rubble out of my 220g) up beside my pc. Now it has a good light and lots of flow but what can i keep in it. I would like a couple hermit (from the 220g ) Probally a few mushrooms but im looking for 1 interesting thing in there to keep an eye on when at the pc. Fish would be great but i cant think of any that would really stand out. I know its small but what i was thinking was keeping a small fish in ther for 6 months to a year then i could put it in the 220 and start with something else. Any ideas???
thanks

look at the flaming prawn goby. They are extremely small, prefect for a 4 gallon, but they are hard to find.

or a yellow clown goby.
