How to Choose a Good Tank Size for Your Fish
If you are a newbie aquarium hobbyist, you may think that 50 litre tanks are easier to maintain than 100 litre tanks. This assumption is completely wrong and yet very common. A number of factors should be considered when deciding on the right tank size for your fish.
Knowledge and Experience
A bigger tank will need more than just one filter or even a pump system that could be a lot more challenging than a novice aquarist might find convenient enough. If you are an experienced aquarium enthusiast and looking to start keeping larger species, a large tank will look perfect for you. Otherwise, you can safely start with one of those 50 litre tanks. This size would not be so large that it upkeep becomes a feat, yet it is just big enough for the water volume to provide a buffer against water parameter mistakes you might make as 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 to give each fish one inch per gallon of water, but if you do follow this guideline, make sure you consider the adult size of the fish, instead of the size they were in when you purchased them. As well, take note that certain species require more space than others, whether or not they are of similar size. Smaller community fish can usually be kept in at least 50 litre tanks, but there are those that require at least 200 litres of water. Additionally, some species may also thrive better in certain tank shapes. 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.
Maintenance time can often be reduced if the aquarium is correctly installed, so this need not be a large issue in considering the right tank size to buy. A good filter size will flush out most of your tank water’s waste and toxins, and your filter media will have to be replaced once a month, whether we talk about 500 or 50 litre tanks. Changing 10 – 20% of your tank water weekly is often enough to keep water quality high.
While moving from smaller to bigger tanks, you will see a substantial boost rise in price. If you want a big tank but your budget is only good for one of those 50 litre tanks or smaller, just get an aquarium starter kit that already includes some of the tank equipment and decor you’ll need or want. 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.
