Yea, it depends on whether or not you are going to get plants. Lights make the fish colors more vibrant, and are a good choice even if you are not going to have a planted aquarium. I have a 10 gallon with a PerfectaLite full hood. It has a replaceable backstrip that can be easily cut for a filter and/or heater and an access door that runs the whole length of the hood. I just recently got an Amazon Sword and it has been doing fine, plus i really like the light because it comes with a built in floresent light bulb and works great and really improves the look of the aquarium. I highly reccomend this, its very easy, you shouldnt have to ever replace the bulbs and its about 30 bucks. Good Luck
