This fish is one of the most popular saltwater fish around. Their colors are so intense and unique. if they are from the wild they can be hard to keep unless you have them trained to eat prepared foods. Their main diet is copepods and you will usually have to add some into your aquarium so they can graze whenever they want.
With captive bred mandarins its very different. you can absolutely add pods if you like to your tank and they will eat them. you can also just feed them prepared foods that they have been eating like Frozen Brine shrimp and TDO Pellets.
