Welcome, Madison. There are a lot of people on here that can help. I havent seen your thread, but if you can try to get some specifics. Water readings, how big the tank is, number and types of fish (sizes too), if you cycled it or not, how long ago did you set it up, etc. Pics help too, if possible.
Why do I love fish? Because every time I stare into the little world I have created for them, every problem I have just floats away....
