Choosing The Right Fish For Your Aquarium
In any aquatic store you can find hundreds of different species alongside each other - but not all these fish can be kept together, and choosing the wrong fish can result in disaster for your aquarium.
Choosing the right fish is not an easy job for anyone new to the hobby, and most experienced aquarists have at some point purchased a species they would not have gone near in hindsight. A few simple steps can help you to make sure the fish you purchase are all compatible and will live out the duration of their lives happily in your aquarium.
Know your water conditions
A basic knowledge of water chemistry is important for many reasons in fish keeping and keeping an eye on ammonia, nitrite, and nitrate levels will help you avoid any serious health problems. Having a rough idea of your aquariums pH and hardness levels will also help you choose the right fish, since not all fish will live in the same conditions, and dramatic changes can kill many delicate species. Knowing what your water parameters are will allow you to match your water conditions to those of your retailer, ensuring that new fish can settle into your tank as quickly as possible.
A good retailer will know if the fish you wish to purchase will mix with the fish you already have, but if you are not aware of the names of all the fish you have, your retailer can do little to help. Always write down the names of any fish you buy and keep an up to date list of your stock. You can then easily show your retailer your list before you purchase any fish. Should any disasters happen and you find out later on that some of your fish are incompatible, you will at least have a good argument for returning the fish if your retailer previously approved the mix with your list.
