Introducing New Fish into Your Aquarium - Live Aquaria

There are two areas of introducing new fish into an aquarium that you must be aware of:

The dead fish fell victim to ammonia a by-product of their metabolism. All fish produce ammonia and it is lethal to them. In lakes, ponds and rivers, the volume of water is so big, that the ammonia produced by fish is diluted to undetectable levels. However, in a home aquarium, the volume of water is much more limited, and ammonia levels quickly rise and kill the fish. Although the water in a new tank appears very clean, it is in fact toxic.
There are few things to remember and to follow when you’re adding new fish to your aquarium.

Setting up a new aquarium doesn’t have to be time consuming, hard or frustrating – a little planning, patience and a few water changes will make the first 30 days go by quickly and uneventfully. Remember, if in doubt – change some of the water, it won’t hurt and mostly likely will fix the problem. Get past the first 30 days and you’ll find that an aquarium is an easy, beautiful addition to your house or office. To keep it that way, change 25% of the water once a month and clean your filter once a month. Do this and pretty soon you’ll find yourself back at the fish store checking out another tank even bigger than your first one. Enjoy! Quarantining is the process of isolating new fish from your existing collection of aquarium fish long enough to ensure they are in good health.

If the aquarium is not fully covered, it is strongly recommended to fit any openings with screens or barriers. Stressed, disoriented or chased fish will sometimes leap from the aquarium and can do so through surprisingly small openings. The first night is probably the most risky time for a new fish to jump out.New fishes that are intelligently chosen and properly introduced in a precautionary manner are likely to adapt well and find their harmonious place in your reef aquarium community.Expect the inhabitants of your reef aquarium to notice the newcomer and react with anything from indifference to outward hostility. Brief chases, displaying and posturing are common observations in the time just after introduction. You should pay close attention for several hours to watch for any vicious attacks or prolonged chasing. Some aggressive interactions may be delayed until the new fish begins to explore its new surroundings and encounters the various inhabitants and their personalities. This is one of the reasons why it is important to make frequent observations over the hours and days following a new introduction.First thing to check is the quality of your water. It is stressful enough for all the fish involved when new fish are introduced to their number. Do not add to it by making them suffer in poor water quality. The stress in them might reach fatal levels. Make sure that you have the highest possible water quality by testing for the ammonia, nitrite and nitrate levels. Do the necessary changes or cleaning before you add the new fish to the aquarium. If you dont like frequent aquarium cleaning, add an EcoBio-Block to your aquarium to give it the beneficial bacteria and trace minerals that can reduce harmful substances in your water and keep it clean, healthy and clear.Introducing new fish to an already existing aquarium is not as easy as it may seem. There are a lot of things to think about and prepare before you can safely transfer your new fish to your aquarium. You cannot just buy any aquarium fish you want then dump them in the tank as soon as you reach home.Your first step when preparing the aquarium for a new arrival is to rearrange the tank. Your established fish have their own hiding spots, and may become territorial if a new fish is introduced. Rearrange the plants and decorations, which will remove established territories and make the environment new for all of your fish. Make sure that there are plenty of hiding spaces where the fish can go until they get used to each other.
