Purchasing a fish aquarium may seem like an easy task however tropical and saltwater fish need special care and attention to live a happy life. The first thing you will need to decide is whether you plan on keeping fresh water fish or saltwater fish. Generally speaking freshwater fish are a lot easier to keep so if this is your first fish aquarium I would advise a fresh water fish aquarium would be a good place to start.

You will need to make sure you do not add too much food to your fish aquarium, research the type of fish you are keeping before throwing in too much or too little food, adding too much food could be harmful to your tropical fish as they can over eat, also adding to much food could potentially pollute the tank.

Having a balanced diet is essential for aquarium fish, I would recommend that you buy any fish food in small bags or containers rather than bulk buying, this is because over time the vitamin content will gradually decline so to keep your fish food in optimum condition and as fresh as possible buy smaller bags and keep them in a cool dry place.

Anything that is introduced into your fish aquarium should be properly taken care of and monitored, it is important to keep the water in the tank clean by checking for parasites, fungi and bacteria. Although maintaining a fish aquarium is an ongoing task certain fish can lighten the load, it is well worth investing in fish that scavenge as they will clean the tank for you however it is vital to research the type of fish you buy to ascertain if they can live peacefully with the other fish residing within your tank.

It may be a good idea to create yourself a daily monthly and weekly 'to do' list so you can be sure that you have made all the necessary checks on the temperature control, lighting and feeding. Toxic and harmful products can be caused by the breakdown of protein, investing in a protein skimmer can be extremely effective.
A protein skimmer will remove impurities and residue from the aquarium and will purify the water.

Never keep your tank in direct sunlight, this will increase the growth of green algae making your tank unattractive and hard to see into. Having a fish tank in direct sunlight will also cause the water temperature to rise making it harder to control

The bigger the fish aquarium the easier it ill be to maintain a stable water temperature, having a larger tank will also give your fish more room to move, it is also very important to give them lots of places to hide, believe it or not the more places they have to hide the less they will hide.

If you can keep on top of the maintenance then you are sure to have a clean and happy tank.
