custom overflow

I have been kicking around the idea of doing a nano reef, with a substantial sump. The question is, how to create a small overflow so that excessive flow is not a problem (and not look stupid)? Or should I drill the tank and simply use an appropriate return pump? I am thinking a few mushrooms, snails, a hermit or two and maybe one small goby? thanks tommy

I was thinking of using a u tube from a small hang on filter and making my own prefilter box, or would it be easier to drill a small tank and make my own overflow into a corner- I have the arcylic- it would be a miniflow instead of a megaflow!

And, how small can I go and keep a single small fish? I plan on using a spare 29 gallon tank as the sump- thinking maybe a five gallon display.
