Setting Up a Quarantine Freshwater Tropical Fish Aquarium

Debating on whether or not you need a quarantine tank? Here is the answer you have been searching for!

Setting up your Quarantine Tank for your Freshwater Tropical Fish Aquarium
When setting up your freshwater tropical fish aquarium quarantine tank you don't need to purchase an elaborate tank. Check out the stores that have occasional freshwater tropical fish sales and see if they have a small tank that will be efficient for a quarantine tank. When you purchase your tank remember to also purchase a filter but be sure to use filter floss that does not contain carbon as this will remove the medication you are putting into the tank. You will also need a heater, a new fish net specifically for the quarantine tank and an airstone.

The Freshwater Tropical Fish Aquarium Quarantine Tank
When you have purchased new freshwater tropical fish you will need to place them in the quarantine tank to be monitored for about 2 weeks prior to placing them in with your other fish. Make sure to monitor the parameters of the water and don't forget to check for the signs that accompany bacterial infections or parasites.

If your new fish appears to become sick or infected with something you will then need to take the appropriate precautions to ensure you can treat this fish and keep your other fish from becoming infected. In order to do this you will need to keep your infected fish in the quarantine tank while you are giving it medication. You will also need to monitor the infected fish for a few more weeks to make sure that there are no other problems that develop. Once you are sure your new fish is no longer sick or infected you can then place him in the large freshwater tropical fish aquarium with your other fish.

Once you have incorporated your new fish into your freshwater tropical fish aquarium there is still a chance that at any time one of your tropical fish will come down with an illness. If this happens just capture the fish with a net and take him out of your freshwater aquarium and place him in the quarantine tank. Make sure to fill your quarantine tank with some water from your main tank in order to avoid having to acclimate the sick fish into the new tank.

Don't be too quick to return your sick fish back to your main tank. Once the illness has cleared up you should still keep him in quarantine for about a week so that you can monitor him closely to make sure you avoid the risk of infecting all of the fish.

Once you have returned your fish back into the main tank make sure to clean your quarantine fish thoroughly. The reason for this is that if you leave the tank uncleaned the next fish you place in there may not have the same illness and you don't want to cross contaminate the illnesses. Never use soap to clean a fish aquarium as the soap will leave a residue and this could cause your fish to become ill. Clean the tank with hot water to kill any germs and bacteria.

When purchasing new fish for your tank, be cautious of the fish stores that always seem to have a freshwater tropical fish sale. If you are looking for a great way to purchase healthy freshwater tropical fish you might want to try searching online. You can buy tropical fish online and have them delivered directly to your door.
