Keep the beautiful mandarin in a large tank - at least 75 gallons. Feed your mandarin its natural food if possible - copepods. Get the fish used to eating brine or frozen shrimp and add frozen artemia. The fish will learn to accept eating frozen shrimp eventually. Add pellets and krill to the diet for good nutrition. If your fish isn't eating or is acting sluggish, that's an indication that something is wrong. Speak to your fish supplier about what can be done.
