Your fish tank is not only meant to provide a home for your pet fish, in fact, but it is also your underwater world that can be styled the way you want it. The most presentable way of adding some character and a unique style to your fish tank is by adding some fish tank accessories that suit your personality, interests, and hobbies. These aquarium accessories and decorations can completely turn the feel of your tank that gives your aquatic pets something to play with or explore. You should ensure that these accessories don’t throw off water chemistry and your pet fish enjoy them as much as you.
But there are a few things that need to be considered before deciding accessories for your fish tank. Let us take a look.
1. The size of Fish Tank
It does no good if you place great large, fancy accessories in your fish tank and it ends up looking oddly crowded, distressing your fish as well giving them no space to move around. Less is good if you have smaller aquariums as it is easy to put 1-2 fun and attractive accessories instead of many that leave no room for your fish.
2. Height of Fish Tank Elements
Fish usually spend their time in the top, middle and bottom zones of your aquarium. So it is vital to keep a free area in each of them. It is better to place 1-2 tall items that go up to the top zone and 2-3 that are smaller an inch or two from the bottom of the aquarium to balance the space available equally. Your pet fish feel secure and comfortable if your accessories are well structured.
3. The Activeness of your Fish
If you intend to keep highly-active fish that have relatively higher oxygen consumption than the dormant breeds, you can keep oxygen-producing accessories like bubble chests and underwater bridges and rivers. These can provide them plenty of air, keeping them happy and active.
4. Color of your Fish
When choosing accessories you should keep in mind their color as they will either compliment or mismatch with the color of your fish. If you are keeping light-colored fish then a dark substrate and dull accessories can assist to complement those hues. In the case of bright fish, they look beautiful and their color pops with pale decorations and green plants against a colorless background.
5. Watch out for Sharp Edges
Accessories like fake plants sometimes have sharp edges that can be harmful to your pet fish by creating injuries and making them prone to infection. So you should ensure while deciding such accessories that they don’t have any sharp edges allowing you to make an aesthetically pleasing aquarium without risking the health of your aquatic pets.
