How to Take Care of Your Fish

A short but helpful guide in keeping healthy fish and a clean fish tank.

Before bringing any fish home you should have your fish tank up and running for at least 24-48 hours. You should let the bag your fish come in float inside the tank for up to an hour so the water has time to equalize. Once the water inside the bag has equalized it's time to remove the fish and place them inside your tank. Scoop the fish out of the bag with a net. Do not pour the water from the bag into your tank.

When deciding on what fish to get for your tank it's important to only put as many fish in your fish tank that your tank can hold. You don't want to place them in all at one time. Not over crowd your tank. Before any fish are added decorations should already be placed inside the tank. Also check the ph, ammonia, nitrite, and nitrate levels. Remember to fill your tank with dechlorinated water and maintain a temperature of 68-78 degrees.

You should have a filter that is of appropriate size for the tank you own. A filter is used to remove waste and provide aeration. A heater is used to help maintain the correct water temperature. A thermometer can be placed inside the tank to keep track of the water temperature. Your fish tank should also be cover with a hood that provides light to the tank, keep fish from jumping out, and to prevent excessive water evaporation.

It's important to have a clean fish tank. A 10% water change is due weekly and a 25% water change due monthly. Always use dechlorinated water when adding water to your fish tank. A gravel vacuum is needed to clean the gravel and a alge scrub to clean the sides of your tank.

Water quality is very important if you want your fish to live. You should test your tanks ph, ammonia, nitrite, and nitrate levels on a regular basis to ensure the proper levels are being kept. Fish show many different signs of sickness, scraping body on rocks, poor growth, weight loss, loss of appetite, golden specs on skin or fins, and white film or spots on skin or fins. Just to name a few.

You should not over feed your fish. This can cause death. Feed fish 1-3 times a day. Only feed as much as the fish can eat in a couple of minutes. Some fish are carnivorous, some are herbivorous, and some are omnivorous. You can add to your fish's diet as needed with meat and vegetables.

If you follow these tips you should be able to maintain a healthy and clean fish. Remember it takes a little work, bit it's very rewarding.
