Chlorine and Chloramine's are used to treat water to make it safe for human consumption. They are two different products added by your water distribution district. As far as I know only one of the two will be used. In fact Chlorine is rapidly being phased out here in the US.
Water that contains either Chlorine or Chloramine's will need to be treated to make if fish or frog safe. To treat Chlorine you use a specific product to neutralize it or expose the water to air for 24 hours or more and the chlorine will dissipate. Chloramine's WILL NOT dissipate in air! To treat Chloramine's you need a different product. Many of the commercial products available today will treat both Chlorine or Chloramine's at the same time.
Here is a link that shows many products available for you to use in treating your water.
