How to Choose a Good Tank Size for Your Fish

If you are a neophyte as an aquarium hobbyist, you may think that upkeep for 50 litre tanks is automatically easier than for 100 litre tanks.Being new to the aquarium hobby, you may be tempted to believe that maintaining 50 litre tanks is necessarily easier compared to maintaining 100 litre tanks. This assumption is completely wrong and yet very common. A variety of factors need to be considered when picking the right fish tank size.

Knowledge and Experience

With a larger tank, you will need more than one filter or possibly a pump system that is more complicated than a novice aquarist would be happy to maintain. If you are experienced in the aquarium hobby and would like to level up and start keeping bigger fish, a large tank is probably the right choice for you. Otherwise, you can safely start with one of those 50 litre tanks. This size would not be too big that it becomes a feat to maintain, yet big enough to give you a buffer against water parameter mistakes you could make being a novice.


Another obvious consideration when choosing a fish tank size is the specie and number of fish you would like to keep. The rule is one inch of fish per gallon of water, but you have to consider the adult size of the fish and not its size when you bought it. As well, take note that certain species require more space than others, whether or not they are of similar size. In general, smaller community fish can do well in 50 litre tanks , but others may need no less than 200 litres of water. In addition, note that some species may also prefer a certain tank shape. For instance, tall-finned species like Angelfish tend to appreciate tanks that are more vertically spacious than horizontally. Although 50 litre tanks will still be 50 litre tanks, Angelfish would like it better if the water was more above and below them instead of on their sides.

Tank Upkeep

Most aquariums require less maintenance time if the aquarium is properly installed, so this is usually not a big concern when looking for the right tank size to get. A good filter size will take out most of the toxins and waste from your tank water, and whether we’re talking 500 or 50 litre tanks, you will have to buy a new filter media once per month. To keep tank water quality high, you need to change 10 – 20% of it on a weekly basis.

Other Factors

As you transition from smaller to bigger tanks, you will observe a significant increase in price. If you want to buy a sizeable tank but you only have enough cash for one of those 50 litre tanks or smaller, you can purchase an aquarium starter kit, which already includes some of the equipment you need, along with tank decorations. If you are only beginning this hobby but want to give yourself some room for growth, pick a tank that is a little bigger than the typical starter tank.
