Currently there is more than 20,000 fish, which to instruct you on care would be time consuming. Therefore, we will cover the basics in tank management to provide you a bit of help. Unlike furry critters on land, fish do not have coats that protect them. Therefore, water temperature is important. If the water temperature is too high, oxygen supply is minimized. On the other hand if the water temperature is too low, it can affect the health of your fish. Along with your aquarium purchase, you should have received a manual, or instruction brochure. It is important to read the material so that you know exactly what temperature and gravity is required to maintain healthy fish. If you have goldfish it is recommended to keep the temperature at 75 degrees Fahrenheit. If you have tropical fish the temperature should be set at 75 degrees Fahrenheit, or 80 to 85 degrees Fahrenheit.



With your aquarium you should supply a thermometer, and sometimes a heater depending on the type of fish you have. Goldfish for example can stand lower temperatures at times.

How is water measured?

Water is measured in pH, which depends on the sourness. Again, it depends on the type of fish you have. If you have saltwater fish, the water is measured at 7.8 up to 8.3. Freshwater fish measures at 6.8 up to 7.2. You want to monitor the pH measurements of water; since the higher the water is measured the more ammonia is produced. If the water temperature is too low it can become harmful to bacteria denitrifying growth, as well as to the gills of your fish. You can purchase buffers, and test kits to maintain pH balance in fish water. Furthermore, gravity is measured in water as well as oxygen, which will discuss shortly.

How much oxygen do fish need?

Oxygen for fish, land animals, and human beings is essential to survival. Without sufficient oxygen the brain will die, which in turn kills the body. Water as well as air, supplies oxygen to fish tanks: You can increase oxygen by using pumps or air supply, which will provide turbulence that creates oxygen. In addition, if you keep the water cool it will augment oxygen supply.

How is gravity measured?

Gravity is based on the amount of chemicals added to the water. If you supply your aquarium with unadulterated water it has a 1.0 gravity in ionic. If your fish come from saltwater you should have a gravity level no higher than 1.023, however you can reduce illnesses for saltwater fish by keeping the gravity level at 1.017. Non-marine or freshwater fish can benefit from a low volume of salt added to the water, especially to reduce stress. You can purchase refactometers and test kits to maintain gravity level.

How do I maintain saltwater fish aquariums?

This is a stressful question; since saltwater fish are marine creatures that habitat in environments where changes are consistent. As well, it depends on the type of aquarium you've purchased to keep the fish. If you've purchased a larger aquarium it is easy to maintain saltwater fish by keeping the environment stable. If you haven't already purchased saltwater fish take note that the Damsel's is an aggressive saltwater fish that does not mate well with other fish. However, this type of fish is easier to maintain than a wide array of other saltwater fish.
