Question: 
I bought a beta fish a week ago and today he seems sick. He is not eating much and is floating on the bottom of the tank. Is he dying?
Answer: 

The most important aspect in fish health is good water quality.
Have you tested your water lately? If not, PetSmart offers free water testing. Bring in a container of your aquarium water today and the PetSmart associates will test it for you to see if you have any toxic ammonia, nitrite or nitrate in the water. You can also pick up free guides on fish diseases and on water quality in the aquarium.

To maintain a healthy environment for fish, you need to change 10% of the water every week in your aquarium, or at least 25% of the water every 4 weeks. Take out the old water and replace it with dechlorinated fresh water. Doing that will keep your water clean and your fish healthy.

If this is a new tank, it is not cycled. What size tank? Is it cycled? A betta should be kept in at least a 5 gal which is heated and filtered. The filter will cause your tank to cycle ie start growing the good bacteria that will "eat" the ammonia produced by the fish, which helps to keep your water healthy. Until it has cycled, you need to test the water frequently and do partial water changes every week, more often if it is cycling as you will have high ammonia (which is toxic to fish) until the bacteria take over. Fresh clean water is important for all fish. Otherwise it is like swimming in a toilet, as the fish obviously go to the bathroom in there. Good water quality is key.
