Blue tang fish or non-aggressive species of fish. These are mostly found in the wild, but they can be kept as pets as well.

Blue Tang Fish Habitat and Tank Requirements

These fish have blue vertical stripes running down their bodies, with a white body and blue tail fins. As a pet, these fish need to be kept in a saltwater tank, and they are best suited for marine aquariums. They need plenty of space and also need company of their own species.

They are very active and playful. They need a tank that is at least 75 gallons in size with plenty of places to hide. They should not be kept with aggressive fish, but it is a good idea to keep them with other non-aggressive species.

Blue tang fish should be fed a variety of foods, including live brine shrimp, krill, silversides, and mysis. A good way to give them the variety they need is by using different types of prepared foods.

They swim around their tanks constantly, looking for food and playing with their fellow companions. They like to play with plants, rocks, and even other fish!

Water Conditioner

A water conditioner is an additive that will make the water safe for your blue fish. The water conditioner contains carbon, which neutralises ammonia, nitrite, and nitrate in the water. It is a very important part of your aquarium’s water cycle. Without it, you would have to change fifty percent of the water every week to prevent harmful toxins from building up in the water and harming your fish.

Fishes need oxygen, as well as all the other nutrients found in their natural environment, such as minerals and trace elements. Conditioner enables these substances to be dissolved in the aquarium water.


A tank filter is a device that removes solids from the water in a fish tank. It serves the same function as a water filter for an aquarium and is designed to keep the water clean for the fish, plants, and other aquarium occupants.

You can use either a wet-dry or under gravel filter in your fish tank. Wet-dry filters are more effective, but they are more expensive to purchase and maintain than gravel filtration.

Aquarium Heater

You will need this if you live in a cold climate or if you keep tropical fish. This is a device that keeps the water in your aquarium from getting too cold.

A heater will not make the water warm; it will just keep the water from getting too cold. If you live in a cold climate or if you keep tropical fish, you should consider using an aquarium heater.

Aquarium heaters may be submersible or placed inside an aquarium. They are controlled by a thermostat and are usually combined with an automatic temperature controller. It is important to purchase a good-quality aquarium heater because they have the potential to cause fires when they malfunction.

Air Pump

The air pump is a device for oxygenating the water in your fish tank. They are typically powered by electricity and are used to keep the water in your fish tank healthy and clean, allowing dissolved oxygen from the surrounding air to be absorbed into the water.

The air pump can provide oxygen for your aquarium in two ways. After the aquarium has been filled with water, the air pump can use a tube to force air bubbles through the water. In this process, the air bubbles dissolve into tiny air pockets within the fish tank water, providing oxygen for your fish.

Another way an air pump can provide oxygen is by removing some of the carbon dioxide or other gases that are produced as a result of normal metabolic processes in your fish. This process is called aeration, and it also helps to keep your aquarium water clean by removing toxins like ammonia that would otherwise pollute your fish tank.


This is a layer of material underneath the gravel on which your plants and animals can grow and live.

Bacteria, plants, and animals all need substrate to live on. The bacteria and plants help cycle the water in your aquarium while the animals eat the plants. Without substrate, your inhabitants will die of starvation.

Tanks with no substrate at all are known as “bare bottom tanks.” They are used for tanks containing fish that aren’t bottom feeders, like angelfish and butterflyfish.


Lighting is an important aspect of fish tank maintenance. If you have live plants in your tank, they will require light to survive. They can also be used to grow macroalgae as well.

If you are planning on using live plants, it is recommended that you invest in high-quality lighting for your fish tank. Most plants need a lot of light to survive and thrive. Low light levels may result in stunted growth or even death.

Aquarium Fish Test Strips

They check the alkalinity and hardness of your water. They will help you keep track of the quality of the water in your tank and make adjustments as needed.

Without the right tools, you will find yourself struggling to keep your fish healthy. You need an aquarium test kit that can help you monitor the condition of the water on a regular basis.

Tropical fish are very sensitive when it comes to water quality. The wrong pH or salinity levels can cause them to become ill and even die.
