Something Interesting For A 20g!

[promithius]

Heya guys, im just weighing up my options for my spare 20g. its 2" long, 16" high, 12" deep (i think, if im wrong its by about an inch or 2)

i LOVE the look of mudskippers, but i dont really think i could do it with such a short length in the tank. id recon id want 3ft long really? please please correct me if im wrong though!

So, can anyone think of any other interesting brakish fish/inverts?

And yes mudskippers ideally need a 30g long

gobys are actually very nice fish, i have brackish and just have a freshwater moray and i cant seem to find any gobys of any kind at any petstore, puffers are a nice choice but some look better then others in my opinion i think a nice looking puffer would be a great choice
