Diet Of Green Mandarin Dragonet  

The diet of Green Mandarin Dragonet is the hardest or the most complicated part of owning one of them. They have a unique or specific diet. These species of fish are carnivores and their food includes small invertebrates, the favorite being the copepods.

As they mostly eat live foods so it is better you have live rocks in your aquarium so that the copepods can exist for your Mandarins to eat. You can buy copepods and keep restocking them as one batch finishes. But it can become costly as these Mandarins gobble them up every chance they get.  

Instead of buying copepods again and again you can breed them. First what you can do is get a larger tank. With larger tanks, the copepods can breed and some can get themselves acquainted in hiding spots. Another best way is to get a refugium. Getting a refugium is probably the better option.  

As you know copepods are their favorite food, but there are alternatives for everything. You can feed them amphipods, live brine shrimp, artemia, and frozen foods as well.

They need a larger tank because you need copepods in the tank otherwise in a smaller tank they can gobble up the pods in a matter of minutes. You will have to give them some space for pods to breed. If you keep them in a smaller tank the pods will be over in an instant and they won’t have anything to eat. This also means that if you are planning to keep a pair then you will need a 60-gallon tank.  

Temperature and Water Parameters

Tank setup and care  

For Green Mandarin Dragonet, let’s first begin with a large tank. A large tank is a must for the copepods, and the importance is already spelled out. Live rocks are a must as these species won’t be able to get nutrition without them. The substrate is best if you use live sands. You will also require rocks and corals for them to have some hiding spaces.  

In terms of pieces of equipment a filter, protein skimmer, and heater are a must. You will have to keep the water temperature and water parameters in the proper ranges. Temperature fluctuation doesn’t go well with them. It is also important that you maintain the cleanliness of the water and keep the toxic chemicals at bay. If you don’t, they can get sick.

A water pump is not necessary as not much water movement is required. You must also do water changes of about 10 to 20 percent.

Remember during water changes, the water you will be adding must be similar to the conditions of the water in the aquarium. You must do this to not shock the Dragonet. If you’re worried about parasites, you need not as they don’t have scales, and their body is covered with mucous. 

Green Mandarin Dragonets can fall sick easily if the water parameters are not right and if the water is not clean, and inadequate nutrition. You will need to look out for sicknesses such as discoloration, fin rot, cloudy eyes, wounds, and loss of appetite.

Keeping two male Green Mandarin Dragonets is not wise as well, as they can show aggression towards one another. So if you want to keep a pair, you should keep a male and a female.  

The best species of fish that you can keep them with are Clownfish, Firefish, Royal Gramma, Watchman Goby, Green Chromis, Pajama Cardinals, Small Damselfish, and Coral Beauty.
