Woah there! Don't go out and get more fish yet. Since you aren't sure what parameters are then I am going to assume you are following fish store directions of fill the tank, let it sit for 24 hrs, and then add fish. Sadly, this is anything BUT cycled.
First, go out and buy an API freshwater master test kit. This will allow you to test for ammonia, nitrite, nitrate, and pH. These are your base parameters for an aquarium.
Next take a look at this link for how to properly cycle your tank.
I just learned about cycling but I already have fish. What now?! - Aquarium Advice
