DO beta fish really need to be in bottled water or is tap water good enough?

I know there is some chlorine in tap water, and the pet shop employee said I need bottled water for them, but would they really be just as healthy in tap water?

    Tap water, treated with a good dechlorinator is the way to go.

    Here are the basics you need to know for your Betta to live a long and happy life:

    1. A cycled ( http://www.firsttankguide.net/cycle.php and http://www.aquaticcommunity.com/aquarium/cycling.p... ) 5 gallon or larger aquarium is minimal for a single Betta.

    2. A filter is necessary in any tank in order to keep the water aerated and free of toxins. For Bettas it is best to set the filter flow to low, as they are not very strong swimmers. Another good option is a sponge filter. If your current filter is too strong, you can remedy it by covering the intake with a pair of pantyhose, putting a tall plant in front of the output, or follow these instructions to outfit your filter with a simple current/flow reducer: http://www.petfish.net/kb/entry/347/

    3. A heater is essential. Bettas need warm steady temperatures of about 80F, to thrive. Constant fluctuation leads to stress, which inevitably leads to disease and often death. You can find an inexpensive heater for a small tank at any fish store.

    4. In a 5-gallon or larger tank, weekly 25% water changes, using a gravel siphon are necessary. Water conditioner must be added to the new water before it is put in the tank to remove toxic chlorine, chloramine, metals, etc. Never change all of your Bettas water, as this shock your Betta, and ultimately weaken him. The Betta stays IN the aquarium during water changes.

    5. Bettas enjoy a well planted aquarium, (use live or silk plants, plastic can tear their fins,) with a cave or two for exploring and resting. The tank should not, however, be stuffed with plants, as Bettas also need a good amount of room to swim. (And swim they will if given enough space.)

    6. Feed your Betta a good staple, carnivore- specific, pellet or flake diet, substituting frozen foods such as brine shrimp and blood worms several times per week. Reserve one day per week for fasting.

    When properly cared for, Bettas have been known to live for 10 years. I have personally known them to live for 6.

    All good answers already. I just want to add, you do not need (and should not use) bottled water for fish. It lacks essential minerals they need. That's just a gimmick some pet shops use to part you from your money. Tap water with a good water conditioner added (such as AquaSafe), is the ideal environment for your fish. Plus, that is often all that is in the bottles you're paying so much for!

    Please go to a book store, library or fish store and get some beginner's books on aquarium keeping. The more you know, the better your chance of success!

    Just use tap water, but you (must) use a water conditioner to neutralize chlorine first.

    By using tap water directly without using water conditioner, it is one of the leading causes for fish dying for beginner fish keepers.

    I use something called TAP SAFE http://petfix.co.uk/interpet-bioactive-tap-safe-30... You add it to normal tap water and mix it then just pour it in. You dont need very much either so a £3 bottle lasts ages.

    Fishless is right! But just to add to the advice, I personally use Tetra AquaSafe to treat the tap water. It neutralizes chlorine, chloramines, and heavy metals present in tap water that can be harmful to fish.

    Another good product which is actually better but more expensive is Seachem Prime.

    IF the tank's not cycled then a bit of chlorine will be the least of your worries.
