Angelfish make brilliant pets, and they are easy to recognise by their triangular, elongated dorsal and anal fins and they also have striped and colourful bodies, it is their appearance and nature which make this species of fish a popular addition to aquariums. If you are thinking about beginning an angelfish aquarium, then there are a few things that you need to consider before you begin, this is to ensure that you can properly look after the fish and keep them happy and healthy so that they remain great friends for a long time.

The first thing you should think about when preparing an angelfish aquarium is the size of the tank which the angelfish require. When working out what size of aquarium you will need, you should consider the ratio of angelfish to the gallons of water to make purchasing a tank easier. For example, you should use one gallon of water per angelfish which is nickel sized. If you are purchasing larger angelfish, or adults, then you should consider that a full grown angelfish will require at least four gallons. So if you are planning on keeping more than one angelfish in your angelfish aquarium, you should consider this rule of thumb when deciding upon the size. So, if you wanted to keep four fully grown angel fish, then you would need an aquarium that could hold at least sixteen gallons of water.

If you are planning on breeding angelfish, then the tank should be at the very least, fifteen gallons, but if you are planning on raising the angelfish fry with the parents then the size of the tank will increase dramatically and you should consider a twenty five gallon tank at the very least. When it comes to an angelfish aquarium or with any aquarium really, you should always think about the temperature of the water. Each species of fish requires a certain temperature to survive in, based on what they are used to in the wild. For angelfish, if you are planning on breeding then you should keep the water temperature at around 80 degrees because this will boost their immune system for better breeding. However, if you are not planning on breeding you angelfish, then they can be a little bit more adaptable to water temperature. A lower tank temperature could result in a longer lifespan for the angelfish; however it does inhibit and slow down growth. Between 74 and 78 degrees is ideal for non breeding angelfish, but if you are not quite sure about the temperature of the water then you should always monitor your fish with a thermometer designed specially for aquariums.
