Im a beginner but would like a 10 gallon tank. How much would it cost to get a tank/a light/great filter/air filter? Also the price of gravel and water sanitizer. I want to spend at least as possible but also get a good prodect. I'm going to fill the tank with platies, I have two now and found that they are perfect fish. There names are Mick and Yetti. (thaey are both males)
