The most important supplies needed for an aquarium are a fish tank, filter, heater, thermometer, lighting, substrate, decorations & planets, and water treatment products.

The size of the fish tank you need depends on the number and size of fish you plan to keep. A general rule of thumb is to have 1 cm of fish per litre of aquarium. More aggressive fish such as Cichlids will need to have more space to avoid conflict.

It is best to clean your aquarium once a week. This includes performing a partial water change (1/4 to 1/3), cleaning the filter in the dirty water, and removing any debris from the substrate with a gravel cleaner and decorations.

Yes, you can use tap water for your aquarium. However, it's important to treat it with a water conditioner also known as chlorine neutraliser to remove any chlorine that is harmful to your fish.

You should perform regular water changes, test the water and adjust if necessary, avoid overfeeding your fish, and clean the filter regularly. Additionally, you can use water treatment products to neutralise harmful chemicals or bacteria in the water.

There are some stores that will ship fish directly to you via courier. The most common way to getting the fish you need is by visiting your local aquarium.
