Accessories are important for keeping your tank clean, well lit, and at the right temperature for your fish and other aquatic pets. Be sure to do research on the specific inhabitants of your aquarium so you know what they need to thrive. Here are five basic accessories that most aquatic pets require.


1. Filtration Systems: Filters are a necessity for any tank since they break down toxic ammonia which naturally builds up in tanks inhabited by fish and other pets. A filtration system cycles water through small filters to catch any bits of food or waste that could cause dangerous buildup in the tank. Filters with activated carbon are used to absorb toxins from the water in your tank.

2. Lighting Systems: Lighting is vital for any aquarium because it mimics the natural light of the sun. This can encourage aquatic plant growth and help your aquatic pets maintain their circadian rhythm, which is necessary for their health and well-being. Lighting also helps your fish see during the day so they can easily get around obstacles and can find their food at meal time.


Tip!

Lighting requirements will depend on the species of fish, or crustaceans, and the types of aquatic plants you are supporting, so be sure to read up on their specific needs.

3. Heaters & Thermometers: Some species of fish like goldfish thrive in cooler temperatures, while tropical fish, such as angelfish, guppies, and tetras need warmer water to survive. Most tropical fish require a water temperature around 78° – a thermometer will be vital to make sure you are maintaining the right temperature.

4. Decor: Some type of substrate like gravel along with plants will provide a natural-looking habitat for your fish while helping to filter toxins and stabilize the water levels. Gravel comes in different colors and shapes to give your aquarium a touch of personal style. You can add other decor to help stimulate your fish’s minds by giving them places to explore and to hide in – this is a great way to enhance your fish's happiness and quality of life.

5. Aquarium Stands: Stands made to hold specific-sized aquariums are a great accessory to invest in for your fish tank set up. Choose an aquarium stand based on both the dimensions and weight (water included) of your fish tank to ensure a safe surface. This can protect your normal furniture from potential splashes or spills, and stands also often have storage cabinets so you can neatly store away supplies for an aesthetically pleasing look.
