A good top-water fish for my nano

[DarthPadre]

I want a single top-water fish for my 20-gal. nano, but I often leave the top off my tank for cooling. Should I stick with bottom dwellers like my goby, or does anyone have any suggestions about a good fish that won't necessarily jump? One with personality, of course.

I like my little citron gobie. He perches everywhere, on the side of the glass, on corals etc. lots of character. Also my pygmy angel swims all over the place also.....both are great and as my tank is open on top neither of these fish have jumped and they have been there for over 3 years.
