Yes, tap water may contain chlorine or chloramine. Either can be toxic. Chlorine will dissipate if water is left out for 24-48 hours. This is called aging. Chloramines (used by many municipal water systems) will not dissipate and must be removed chemically with a water conditioner. StressCoat by API or NovAqua Plus by Kordon are both adequate conditioners. Look in the aquarium section of the local Petco or fish store for them.
