Ornate Butterflyfish

General information

The Ornate Butterflyfish (Chaetodon ornatissimus) is a small, colorful, and popular saltwater aquarium fish. They are typically found in the Indo-Pacific region, from the Red Sea to the western Pacific Ocean, and are commonly seen around coral reefs in shallow waters. They have a distinctive and ornate pattern of yellow, black, and white on their body and fins, making them an attractive addition to an aquarium. 
Adult Ornate Butterflyfish typically grow up to 7 inches (18 cm) in length, but can reach up to 10 inches (25 cm) in the wild. They prefer a well-lit aquarium with plenty of live rock and hiding places, and are generally peaceful towards other fish species, although they may become territorial towards their own kind.

Ornate Butterflyfish are omnivores and require a varied diet that includes both meaty and plant-based foods. They may be fed a combination of flake or pellet food, frozen or live brine shrimp, mysis shrimp, krill, and chopped seafood. It is recommended to feed them small amounts of food throughout the day, rather than a large feeding once a day.

There is no visual difference between males and females in Ornate Butterflyfish.

Breeding and spawning of Ornate Butterflyfish is difficult and rarely accomplished in home aquariums.

Ornate Butterflyfish are susceptible to common saltwater fish diseases, such as white spot disease, marine velvet, and bacterial infections. Regular water changes and a proper diet can help prevent these diseases.

The Ornate Butterflyfish is found in the Indo-Pacific region, from the Red Sea to the western Pacific Ocean.

Ornate Butterflyfish are generally safe to keep with other peaceful fish species in a well-established aquarium. However, they may become aggressive towards their own kind, so it is recommended to keep only one per aquarium. Additionally, they may nip at corals and other invertebrates, so caution should be taken when keeping them in a reef aquarium.

It is important to acclimate Ornate Butterflyfish slowly to the aquarium environment. The fish should be floated in the aquarium in a bag or container for approximately 20-30 minutes to allow for temperature adjustment. Then, small amounts of aquarium water should be added to the bag or container every 10-15 minutes until the bag is full. Finally, the fish can be gently released into the aquarium.
