Description Gold Nugget Maroon Clownfish is a designer clownfish and a variation of the Gold Stripe Maroon Clownfish. Instead of three golden stripes, the Gold Nugget Maroon has a solid golden color covering its body. Its face and fins are still a deep maroon color although various spots and markings often can be found in the face. Also, the golden color penetrates the base of each fin and almost entirely in the dorsal fin (front top fin). A remarkable feature about the Gold Nugget Maroon is that they start out white. This is similar to the Gold Stripe Maroon Clownfish that starts out white as well. As the fish grows, the color change from white to its final golden color. This typically happens when the fish is about 1 to 1 ½ years old and about 2” or a little larger.
Temperament & Captive Care The Maroon Clownfish is the largest known species of clownfish and has developed a reputation for their bold behavior. The females can grow to 6” and can be very territorial especially when defending a nest of eggs. It is best to not mix maroon clownfish with any other clownfish species in your tank and to only keep a mated pair or a single fish. Captive bred Maroon Clownfish are generally less aggressive compared to wild collected fish.
Feeding Maroon Clownfish have a healthy appetite. Most clownfish are omnivorous feeders, meaning that they will consume a variety of different food types. In nature the diet of clownfish consists of crustaceans (such as copepods and amphipods), algae, polychaete worms and leftovers from the anemone’s meal. Our captive bred fish are conditioned to eat a variety of aquarium diets including pellets, flake food, frozen Mysis shrimp, and frozen brine shrimp.
