Important Instructions For Fish Beginners


There are many important instructions and factors to consider BEFORE buying your tropical or marine fish aquarium. These are :

Tropical Or Marine Fish

Maximum enjoyment is probably the most important factor when starting your new fish hobby. Cost is significant too! Most newbies start off with tropical fish aquariums, as they are cheaper than marine tanks to set up.

Marine tanks require more specialized equipment, and the fish are considerably more expensive when compared to tropical fish. Adding live corals can inflate the cost as well.

If you've got your heart set on a reef aquarium, you might consider a fish only reef aquarium.

(The other type of reef aquarium is the Fish-only with live rock - (FOWLR). 

Extra work is required when setting up both types of the marine tank for, e.g., Salinity levels for the tank, mixing the saltwater before necessary water changes, taking care of the live rock and including unique lighting systems required for the corals.

Although being more expensive to set up and run than tropical fish aquariums, marine reef aquariums are very popular and are visually incredible to see.

Ultimately, the choice is yours - but beginners to this hobby tend to start with a tropical fish tank. There are many beautiful types of tropical fish to enjoy, without the added stress of setting up a complicated marine reef tank.

 Size - ( A Larger Tank Will Save You Money )

The absolute minimum size of your fish tank, will depend on what species of fish will live in it. The bigger the fish, the larger the tank will need to be. As a general rule of 1 cm per litre of water for adult fish, you will need a 20 gallon fish tank to house 20 small / medium size fish.

A large aquarium can hold more fish, and it holds more water which helps dilute harmful toxins, and can be cycled easier and quicker for the first initial set-up. For this reason alone - It is best to buy a larger fish tank that you can afford.


It's best to set up your home fish tank, where you will spend most of your time, ideally -  in your living room. Most living rooms have a large surface area, that can accommodate most fish aquariums, whether it is placed up against a wall, in an alcove or corner wall.

Plus it is a lot easier cleaning and maintaining your fish tank when there is room to do so.Make sure that there is plenty of space and ventilation around the aquarium, which stops mould,and heat build up inside. Keep a cover on the aquarium which will help keep humidity levels down.

Do not place your aquarium near to open fire, radiators, and doorways, or exits, as this will fluctuate the temperature, in and around the fish tank, no good for the fish, as they will be more stressed. Direct Sunlight is no good either, as this will aid algae growth, and increase temperature!

A Glass or Acrylic Tank

This subject is a 50:50 question for you, there are pros and cons to each manufactured tank. Glass is tough to scratch whereas acrylic can scratch very quickly - not ideal for a smaller fish tank.

However, acrylic is considered lighter than glass. An acrylic manufactured tank can weigh five times less than a glass fish tank of the same water volume.

It is for this reason that many 500-gallon fish aquariums are made entirely of acrylic, to keep the weight down, and to save many household floors from damage.

Therefore it is vital to do initial research from a reputable online source, to determine which beginner fish is best for your needs.
