Notice the goldfish......this is for aesthetics in a freshwater aquarium.
Lighting is very important in reef tanks.....not so much in FISH ONLY tanks.
Are you going to have any corals, polyps, mushrooms, etc? If so, don't cheap out on the lights....get yourself some good wattage Daylight & Actinic lighting.
If you are a FISH ONLY tank, you can use basic fluorescent lighting.
Give us some setup & tank details?
Also, if you are new, you shouldn't be adding fish so fast. One fish per two-three months average.
