What would you do with 50 gallons?

I can't decide what to do with a new tank: medium-ish light planted or FOWLR (possibly low light corals) so I'm posting in SW and FW for ideas.  I do know I don't want to do cichlids.  The tank is 36"x16"x20" and lighting is 2x39w T5HO.  Any thoughts...?

Toby puffers (such as a Valentini, Papuan, Sharpnose, etc.) would be darling choices.

How about a high flow, low light non photo synthetic tank with some very low light corals. You could have gorgonia and some leathers in it.

I am building one myself too

OR

A sw planted tank with various macro algae like sargassam, halimeda, mermaids fan, shaving brush...

interesting ideas Pat, what about fishies? 

okay toby puffers are ADORABLE.  the black saddled one in particular.

Well for my low light tank I may put in a small school of anthia. The fact that they need to be fed 3 times a day at least shouldnt be a problem as their waste will be feeding the gorg's.
I may also add a small school of black sailfin blennies.

Now for the planted tank you would want to avoid any fish or grabs that would pick at the algae you are growing so no tangs of emerald crabs. I would probably let the tank mature for a bit then add some pipe fish or sea horses.
