The water will evporate on its own over time.
Fish or invertebrates scooped and filtered from water, either fresh water or marine.
No just fresh water and a loving home! :)
No, you should be able to use it
Saltwater fish require salt water, and fresh water fish need fresh water, you can't mix them, or the fish will die. You need to look at each individual fishes needs as to what temp they need their water to be. There are some saltwater fish that can survive in fresh water, but it is not healthy for them.
Most pet stores that sell fish also sell fresh and salt water fish. Read up and learn about salt water tanks because they are different to take care of than a fresh water tank.
No, any additional animal put into a confined volume of water will increase ammonia levels and will therefore not keep water 'fresh'.
No.
Mollys (Poecilia sp.) are usually regarded (and kept as) fresh water fish but they actually come from brackish water originally. With slow and carefull conversion they can be kept in fresh or salt water environments.
Fresh water
AnswerThere are generally two types of aquariums: Fresh water and salt water. The most common tropical fish available for a home aquarium thrive in fresh water. For fresh water aquariums, people usually use tap water, but treat it first with commercially availble water treatments to remove harmful properties, such as chlorination (chlorine present in tap water will kill good bacteria that the fish will need to survive), and to obtain a pH balance that will be agreable with the fish. You can get a simple bottled chemical treatments at most any pet store.I recommend following the link below to learn more about water for aquariums.http://faq.thekrib.com/begin.htmlAnswerSome are concerned about using filtered water (RODI) as it takes out the chemicals the fish needs. This is not an issue in saltwater aquariums as the salt mix will add the needed chemicals. This may cause problems in freshwater tanks, however preparations are available to add the missing chemicals in filtered water. RODI water is a must in Reef tanks - it saves problems down the track.
fresh water .my fish are 16 yrs old
Fresh water fish survive just as well as fresh water fish. Maybe this question isn't the one that you actually meant to ask?
