What fish are good for a ten gallon tank?

Get small community fish (i.e. mollies, platys, danios, tetras, etc.). Stay away from goldfish, they are suppose to be in a large tank as they are meant to reach 12" in size. If you had goldfish in the tank originally, scratch it and start fresh. Get all the water out to avoid future ammonia poisoning to community fish. Patience is the most important. It is best to start with one or two community fish, I recommend danios as they are hardy and small, then when the water cycle is complete, about one month after introducing the new fish, you can add a few more. I wouldn't do more than 5 or 6 in the end if you want them to be healthy and live a long time. Good luck.
