Is it wise to keep fish in distilled water? The answer. It’s probably not the wisest of decisions. Why not? Because distilled water is free of minerals needed for a healthy fish. So, what is the best type of water for your fish?

Nine out of ten experts agree that aged tap water is the best for fish and that includes both male and female. Side point: In some cases bottled water is alright as long as its a well known brand and you don’t mix different brands in the same tank or bowl. The bottom line is . . . Just don’t use distilled water if you want to enjoy a happy and healthy pet with a guaranteed long life span.

What about aerated water?

Here’s something else you should know about water. Fish and aerated water are not really a good mix at all! You may think that aerated would be just what a fish needs but keep in mind that a fish has billowy type fins, and too much water flow and movement isn’t really good for them at all. Put a fish in this type of situation and it’ll appear as it’s swimming constantly upstream. Keep in mind too that fish are more inclined to suffer from the dreaded "fin rot". And with calmer water you dramatically reduce the chance of this happening to your pet.

Fish are tropical and thrive in water with a temperature (24-27 degrees Fahrenheit) around the 75 to 80 degrees Fahrenheit range. Too cooler temperatures and you’re taking a chance on your fish succumbing to all types of diseases. Higher temperatures and your pet fish will display signs of real distress. Usually this relates to a difficulty in breathing. If the temperature in the room is within the specified fish water temperature range you won’t need to worry or even install a heater.

If it isn’t, then you will need to install a heater so that the water temperature is maintained at a proper level so as to keep your fish happy and healthy. In conclusion: you’ll need to check on the ammonia level of the water too. If it’s too high this could be fatal to the fish. Just pop down to your local pet stop and pick-up a water testing kit. They’re relatively inexpensive and it will help you keep an eye on the quality of the water. You can find other helpful advice and information regarding water temperature
