AQUARIUM - The Bigger, The Better, The Easier!

Strangely enough the larger the aquarium the easier it is to care for. The more water you have in your aquarium makes it easier to obtain a balanced environment for your fish.
When starting out with keeping fish we would recommend an aquarium of 100 litres or higher.
Deciding on the right type of aquarium for your needs can be tricky. You need to establish how much space you have, what shape, size, and type of aquarium will be best, and where you will place it in your home.
If you’re short on space, a smaller, square, or oblong aquarium may be the best option. Round aquariums tend to take up more room, but they can be easier to maintain since there are no corners for debris to collect in.
If you’re putting the aquarium in a corner, make sure you measure the space correctly so that it fits properly and doesn’t look out of place, a triangular tank will look amazing but these are generally taller and not so easy to maintain.
Once you’ve decided on the size and shape of your aquarium, you can start thinking about what type of fish you want to keep. Some fish require more space than others, and some need specific conditions to stay healthy.
Do your research to make sure you choose an aquarium that will meet all of your fish’s needs depending on the fish type.
With a little planning, you can find the perfect aquarium for your home.
