If you don't want to read the recommended threads at the top, here's what my tank consists of. Its a copy from an old post of mine but it's a typical reef setup.
"""75 gal saltwater
Filtration: 2x Emporer biowheel filter, reef octopus 800 p. skimmer
Nitrates: 0.0
Ammonia: 0.0
Nitrites: 0.0
PH 8.4
Salinity 1.022
(tested moments before this post)
KH=10
and blah blah blah reef specific tests are all normal.
106lbs of live rock, plus 2 inches of live sand.
Lighting is a coralife beast that cost me $800 but i cant remember the name
tank is 2 months old.
Tankmates:
Lyretail chromis (acting passive)
Blue-green Chromis (top level swimmer, no interest in the bottom, ever)
Royal Gramma (territorial, but the goby in question is no where near his turf)
Sixline Wrasse (merely inquisitive, shows no signs of harassment)
Short spine sea urchin, the usual host of crabs and snails in a reef tank, some tiny starfish, and a few patches of button polyps and a brain coral."""
NOW, seeing as you dont want a reef. you dont need more then a pair of blue and white T5 lights (makes the fish's colors stand out). Strongly recommend at least one biowheel filiter of any kind. I swear by those things. You will need a heater, and probably a nice current generating fan to prevent stagnent water.
As far as the fish go, you want easy, pick the 3 meanest fish of the same size at your fish store, DO NOT BUY THEM RIGHT THEN, go home, or go on your iphone like i do and do some research. ask to see them eat, look them over for anything that might be bad for your tank (IE white specs, damaged fins, pale colors, them scratching them over everything, red puffy gills, etc. ) Now I say the meanest fish, but any aggresive fish is in my opinion the easiest type of fish to take care, they're full of personality, and usually arent very demanding. (BTW I LOVE TRIGGERFISH AND PUFFERS). Seeing as your tank is a bit on the small side as far as seawater tanks go, just stick with a few (2-3) fish and you won't have to yank hairs to keep it under control.
