As well as your fish, there are a host of other equipment and accessories you may need to add, including:
Filtration system: This is needed to filter the water regularly throughout the day and keep it healthy. Filters come in a range of designs, but whichever one you choose, it needs to be size-appropriate for your fish tank.
Heater: Even if your fish are not tropical, most will require the fish tank temperature to be around 68 degrees F, while warm-water fish need it to be between 74 to 77 degrees. So, unless your room temperature remains constant, you'll need an aquarium heater.
Thermometer : This is an important addition to your aquarium kit as it means you can continually monitor the water temperature.
Substrate : This is the layer you need to line the bottom of the fish tank and includes gravel and sand.
Plants : As well as looking attractive in an aquarium, live plants also help to keep the fish tank’s water clean by removing ammonia from the water.
Decorations : While the number you have should be limited, those fun accessories such as caves, treasure chests and boulders also have a practical function as they can also provide a hiding or resting place for your fish.
