If you are a newbie aquarium hobbyist, you may think that 50 litre tanks are easier to maintain than 100 litre tanks. While very common, this assumption is totally wrong. 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 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 factor you should consider when determining the right fish tank size is the specie and number of fish you are planning to have. The rule of thumb is one inch of fish per gallon of water, but make sure you consider the adult size of the fish, not their size when you bought them. Remember as well that that certain species need more room than other fish, regardless of their sizes. In general, smaller community fish can do well in 50 litre tanks , but others may need no less than 200 litres of water. Furthermore, tank shape can also be a factor for some species. Tall-finned species such as Angelfish may prefer tanks with more vertical than horizontal space. While 50 litre tanks would still be 50 litre tanks, what matters to Angelfish is that the water is dispersed up and down instead of side to side.
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 eliminate most of the toxins and waste from your tank water, and you will have to get a new filter media once a month, no matter if you’re talking about 500 or 50 litre tanks. Changing 10 – 20% of your tank water weekly is often enough to keep water quality high.
As you transition from smaller to bigger tanks, you will observe a significant increase 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.
