Steps To Maintain A Healthy Fish Tank


A well maintained fish tank will add a lovely, restful, soothing accent to any room.

The first step to keep in mind is to purchase healthy fish and limit the number of fish according to the size of the fish tank.  Stick with fish species that will be compatible with each other.

If you purchase new fish to add to the existing fish in your tank, quarantine the new fish for awhile so you can observe these new additions to be sure they are healthy.

When introducing new fish into the tank leave them in the bag in the fish tank for about 20 minutes.  Then add about 20%  of the water from the tank into the bag and wait another 20 minutes.  Finally you can release the fish into the tank.

One of the most important steps you need to do to keep your fish in the tank healthy is to regularly change the water in the tank.  Set up a regular schedule and change about 25% of the water in the tank each week.  Changing the water helps to prevent harmful contaminants building up.  Do not change more than 30% of the water in the tank at any one time.  Condition the water using one of the de-chlorinating products on the market.


Be sure to test the water in the tank using a test kit to be sure the levels are correct for the fish.   The fish tank filter will process the fish waste in the tank between water changes.

You will need a heater and a thermostat in your fish tank.  Keep the temperature consistent.  Be sure all fish in your tank will be healthy at the same temperature.

Use a timer on the tank lightening to ensure a regular schedule of lighting for the fish.  8 to 10 hours daily of light is plenty for the fish.  If there is a power failure check the electrical equipment in the tank immediately after the power returns.

You want to provide a substrate in the tank for your fish.  Use sand for salt water fish or pebbles for river fish.  For each gallon of water in the tank use about one pound of substrate.

Provide plants or other items where the fish can hide.  Some fish feel more comfortable when they have places to disappear and hide.

Some fish are jumpers so to prevent them exiting the tank you may want to have a hood on the tank.

Be sure to feed your fish on a regular schedule.  Do not feed them a large quantity at one time.  Instead feed small amounts two or three times a day.

These suggestions will help you establish and maintain a healthy fish tank.
