When you put tap water in you need to buy water conditioner. Put the water in, then the water conditioner, and then they fish. You can buy water conditioner at most pet stores. The best thing to do though, is to get a pitcher that has a filter so the water will already be filtered. Although the water is filter you still need water conditioner.
if you just bought the fish let the water in the bowl sit out for about 24hours before putting it in. But make sure that your water has no chlorine in it. NO tap water. If you use tap water you have to get water cleaning drops for the tank.
Chlorinated water needs to be treated before use in any fish tank. It's not just chlorine that's added to tap water that's harmful, but chloramines as well.
Any place that has water (not tap water,a pool,or any chlorined substace or any type of water you can drink.).
No you can not because tap water has chorine that makes fish die
Yes because fish water has nutrients that tap water doesn't have that acts like a fertilizer.
No.
Depends what kind of fish. If it's a freshwater fish, tap water from a faucet that has a water filter in it is good. If it's a saltwater fish, buy sea salt and mix in the right proportions to filtered tap water.
you can use both but tap water is a bit better for them
Tap water is not very good for fish. There are two main reasons. Most tap water has been treated to ensure it is safe for us to drink. This treatment usually leaves some chlorine (in some form or other) in the water. Chlorine is a poison for us and for fish but the level of danger for fish is very very much lower as they are passing water through their gills constantly and because they are so (relatively) small. Secondly, tapwater has little oxygen dissolved in it. This depends on how far your tap is by pipe from the open reservoir. We get our oxygen from the air; fish have to rely on the oxygen dissolved in the water that they pass through their gills. Both these problems mean that a race starts when you place your fish in tapwater. Will the water improve fast enough for the fish to live or will the fish die first? Sometimes the fish wins but it will suffer. Before placing tapwater in an aquarium it should stand open to the air for 24 hrs. This will allow the chlorine to evaporate and the oxygen from the air to dissolve in the water. There are some additives that will ensure that tapwater is safe for fish, available at your local pet shop.
