The Golden Butterflyfish (Bluecheek butterflyfish) is a Red Sea butterflyfish with a vivid yellow body, fine red-orange horizontal lines and a blue-gray patch behind the eye. It is known for hovering motionless beneath table-shaped corals, which makes it a rewarding fish to watch. It grows to a maximum total length of 23 cm and is rated for intermediate aquarists, so it needs a roomy tank and some saltwater experience. It eats hard and soft corals as well as giant clams, so it is not suited to a reef tank and should be kept in a fish-only aquarium. Ask the seller what it is eating before bringing one home.

7 things to know before welcoming a Bluecheek butterflyfish
1A Red Sea native
This butterflyfish comes from the Red Sea and is known for hovering motionless beneath table-shaped corals. In an aquarium, you may see it spending quiet time in shaded spots.
2Grows up to 23 cm
Its total length can reach up to 23 cm (FishBase). Rather than choosing a tank based on a juvenile's size, plan a larger tank that suits the adult.
3For intermediate keepers
Its care difficulty is rated intermediate. Having handled saltwater water quality and feeding beforehand makes it easier to care for calmly. If this would be your first saltwater fish, consider building experience with other species first.
4Check feeding habits
Many butterflyfish feed on corals in the wild, and some take time to accept aquarium food. Before bringing one home, ask the seller what it is eating now. Whether it takes prepared foods is a key factor in how easy it will be to keep.
5Not for coral tanks
It eats hard corals, soft corals, giant clams and fan worms, so it does not belong in a coral tank. Keep it in a spacious fish-only aquarium with live rock it can pick at.
6Shaded rock layout
Because it is known for hovering under table-shaped corals, an overhanging rock structure that casts shade may help it settle in. Since it grows large, also leave open space for swimming.
7Tankmates and health
Pairing with its own species or similarly shaped fish calls for careful observation of how they get along. After arrival, it helps to watch it in a separate tank and keep an eye on its appetite and body surface. If anything seems off, consult someone experienced with saltwater fish.
