It is a good idea to have more than one tank so male and female guppies can be kept separate. Doing so will prevent poorer quality male guppies from breeding and reproducing, and separation will prevent unwanted babies. Proper aquarium maintenance is important in keeping fish healthy and disease-free. Approximately twenty percent of the aquarium water should be siphoned out and replaced once a week. Siphoning water from the bottom of the tank is important since removing water from just the surface does not get rid of debris.
Most pet stores sell siphons that vacuum out waste and leftover food from the aquarium bottom.
The recommended pH level of the aquarium water needs to be between 6.8 and 7.6. The most desirable range is between 7.0 and 7.2. Kits to test and adjust the pH level of the aquarium water are available in most pet stores. Taking time to check pH levels is an important part of maintaining a healthy tank for your guppies. These tiny eggs can be hatched at home and fed as a supplement to flake fish food.
