Green Mandarin

  • Fishes


The Green Mandarin is a unique species of fish found in the tropical waters of the Indian and Pacific Oceans. It is a colorful, small and reclusive creature that has a unique way of life which has made it an intriguing and popular subject for both aquarium hobbyists and professional biologists. The Green Mandarin is often seen as one of the most exotic and attractive looking of all aquarium fish, and its beauty makes it a sought after member of the fish keeping hobby.

Signs of a Healthy Green Mandarin

The Green Mandarin is a relatively hardy species of fish and if it is kept in suitable tank conditions, can live for up to 10 years or more. In order to maintain a healthy and happy Green Mandarin tank, a number of factors should be taken into consideration. Firstly, the tank should be well established with plenty of hiding places and a balanced water chemistry. Secondly, the diet should be well balanced, making sure to include plenty of live foods such as brine shrimp or small pieces of fish meat. Finally, the water should be checked regularly for nitrates and ammonia as these can be detrimental to the health of the fish.

Behaviour of a Green Mandarin

The Green Mandarin is a very social fish and will often form a small group with other Green Mandarins. As such, it is important to keep Green Mandarins in large enough aquariums with ample room for the fish to swim around. They are also quite timid and prefer to hide away in large peace of live rock or in caves rather than in the open.

The Green Mandarin is a very timid species and may become startled at sudden movements and loud noises so a large aquarium with plenty of cover is essential.

Breeding the Green Mandarin

Breeding the Green Mandarin has been a challenge for many aquarium hobbyists due to the difficulty of inducing the fish to spawn. The Green Mandarin is notoriously difficult to spawn, but once the fish have become established in their tank, a breeding pair can be formed in which spawning should occur.

The spawning process takes place in the open water with the female releasing the eggs which are then immediately fertilised by the male. The eggs then settle in the substrate where they will hatch after several days. Once the fish have hatched, they should be kept separately from the adult Green Mandarins to prevent them from being eaten. As with other aquarium fish, the juveniles need to be fed often and provided with a wide variety of artificial and live foods to ensure proper growth and health.


The Green Mandarin is a stunning display fish and an ideal choice for the experienced aquarium hobbyist. Its unique behavioural traits and vibrant colours make it a very attractive fish and an interesting species to observe. In conclusion, the Green Mandarin is a wonderful choice for those looking to create a colorful display with a subject that will remain active and engaging.
