Filters keep the water clean for the fish, kind of like we need clean air to breath properly. Also, filters keep the tank clean by (yep you guessed it) filtering the water. I hope this helped^^
Fish tank filters are not too expensive to keep using. Most of the money goes towards the initial cost of all equipment. You will probably spend about $20 a year on fish filters if you change them as often as you should. P.S., change the filter once a month.

This could be caused by over-feeding. Fish have air bladders and they control how they float in water. If they eat to much this may damage the bladder and in return cause them to float abnormal.
There are a number of places where one can purchase filters for a fish tank. They can be purchased at pet supply stores, such as Pet Smart, and online on websites such as Amazon.
