Signs of a Successful Treatment

How do you know when you have been successful with a treatment for your betta? When your fish stops eating the food you put out for it, you have been successful. When it swims more slowly around the tank, you have been successful. If the fish stays longer at the bottom of the tank, this is a good sign. Also if the fish stays towards the top, this is also good, this may mean your fish is weak and cannot hold enough air. All of this are signs that your treatment is working.
