@adam sounds like your tank is around 5 gallons. I would personally add a small airstone with a small air pump. You can get one from the store or online that is for 10 gallon and smaller tanks and that would work just fine for your fish. It's better to have the airstone than to not.

Aquarium Fish Tank Gravel Stones Substrate Coloured and Natural 2/10 ... You have your perfect tank, complete with all the bells and whistles of filtration. You have your water quality test kit ready. You have a list of fish you would like in your collection. So, how are you going to decorate your aquarium? Believe it or not, this is where a lot of people run into problems. Sometimes they get so excited about all the cute decorations at the pet store that they overcrowd the bottom of the tank. This is no good. Not only will this make doing tank maintenance harder (just think of trying to gravel wash all that), but it also it looks tacky. With that in mind, how do you pick out decorations for your tank? This is the time to be creative, as the sky is truly the limit.

Gravel and stones are popular choices for freshwater tanks. They create a natural look for the tank and they are easy to clean. They are a better alternative to colored glass pebbles which, however pretty, are not always the best choice for a large fish tank. Glass pebbles aren't necessarily bad for your fish, they simply do not provide as much surface area for good bacteria to colonize. You need good bacteria to keep the nitrogen levels in your tank in check. Glass pebbles over time will break down, as is natural, and gravel will erode as well. However, the glass pebbles will have sharper edges whereas the gravel will just become finer. Glass pebbles are pretty, but they are just for show. It would not be harmful to have a few of them scattered throughout the bottom of the tank, as they will add some color. Just be sure to change them out once they begin to show signs of wearing down.
