Do you own a tropical fish? It could be one of the blue mandarin fish you’ve seen going for cheap at the pet store. You may have bought it for decorative purposes but now you have fallen in love with it.

Learning to care for blue mandarin fish is easy once you understand their needs. These fish are popular for a reason. Most new owners find themselves overjoyed by their favorite new pet.

Still, trying to figure out where to start? Here’s what you need to know about caring for your new blue mandarin fish friend.

Tank Size and Setup

Blue mandarin fish, also called mandarin goby, needs a tank size of at least thirty gallons, but a larger tank is always better. A well-planted tank is ideal for blue mandarin fish, who love to hide in plants and live rock. Live rock is essential as it provides a natural food source for fish.

Also, a sand bed is essential for blue mandarin fish as they spend most of their time at the bottom of the tank. Keep your reef aquarium as close to its natural reef habitat as possible for the best results.

Water Quality

Water temperature should be between 75-80 degrees Fahrenheit and pH levels between 8.1-8.4. Keep ammonia and nitrate levels at zero by performing regular water changes. Poor water quality can lead to stress, disease, and even death in blue mandarin fish.

In addition, the water should be well-oxygenated and filtered to ensure it remains clean and free from harmful contaminants.

Feeding

Blue mandarin fish prefer small crustaceans such as copepods and amphipods, which can be established in the tank before adding the fish. They are also recommended to supplement their diet with frozen mysis shrimp, brine shrimp, and other small meaty foods.

It is important to feed blue mandarin fish small amounts of food several times a day to prevent overfeeding and ensure they are getting enough nutrition. A proper diet is crucial for blue mandarin fish’s growth, development, and overall health, and a well-fed fish is less prone to stress and disease.

Compatibility

Blue mandarin fish, also known as blue mandarin dragonet, are peaceful and generally compatible with other peaceful fish. However, they can be territorial towards other blue mandarin fish, and keeping them in pairs in a larger tank is recommended. When choosing tankmates, ensure they are not aggressive or overly competitive for food, as this can cause stress and aggression in blue mandarin fish.

Choosing suitable tankmates and avoiding overcrowding can ensure a peaceful and stress-free environment for your blue mandarin fish, promoting their overall health and well-being.
