What kind on nano tank is the best!

[Carrera75]

I don't have the space for a big tank. Also, I believe that the bigger the tank the more expensive it is as more live rock and live sand are needed among other things. I would like to have 3 or 4 small fish with hardy corals that do not require lots of light.

I have been reading lots about how to set up a nano and apparently it is possible to have a beautiful lookingnano without using a skimmer. The filtration owuld be done with live san, live rock and weekly water changes. Is that true?

cheers
