Choosing the Right Tank Size for Your Pet 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 larger tank will require more than a single filter or even a pump system that is possibly more challenging than a novice aquarist would be comfortable with. If you are an experienced aquarium enthusiast and looking to start keeping larger species, a large tank will look perfect for you. But as a beginner, it should be safe to begin with one of those 50 litre tanks. This size would not be so big that maintenance becomes a burden, yet it is large enough to provide a buffer against water parameter errors you might make because of your inexperience.
Another evident factor in choosing a fish tank size is the specie and number of fish you plan to keep. 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. 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. In addition, note that some species may also prefer a certain tank shape. For example, tall-finned species tend to like tanks that are taller than they are wide. 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 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.
