The Arabian angelfish is a large angelfish from the Red Sea. Its deep blue-purple body carries a yellow crescent-shaped band across the middle, and its tail fin is a vivid yellow. It can reach up to 40 cm in total length, so it pays to plan for its adult size and tank space from the start. The yellow tail is the key to telling it apart from the similar-looking Halfmoon angelfish. It is said to have a bold temperament, so choosing tank mates matters. Rated for intermediate keepers, it suits people who are comfortable with saltwater fish and can set up a tank suitable for large species. Its striking looks can make it the centerpiece of the aquarium.

About Arabian angelfish
The Arabian angelfish is a large Red Sea angelfish with a deep blue-purple body, a yellow crescent band and a yellow tail. It grows up to 40 cm and suits intermediate keepers.
7 things to know before welcoming a Arabian angelfish
1Plan for 40 cm
This is a large angelfish that can reach up to 40 cm in total length. Even if a young fish looks small, choose a tank and filtration that will still be comfortable at adult size. Aim for open swimming space together with rockwork where it can retreat.
2Best for Intermediate Keepers
Its care level is rated intermediate. Getting comfortable with marine water quality and feeding first makes it easier to respond calmly if the fish's condition changes. If this would be your first saltwater fish, gaining experience with easier species first is a sensible option.
3Telling It from Lookalikes
The yellow tail fin is the key to distinguishing it from the similar-looking Halfmoon angelfish. When browsing listings, check the tail color in the photos as well as the overall pattern. If you are unsure which species you are looking at, ask the breeder before deciding.
4Choose Tank Mates Carefully
Large angelfish are said to be territorial and may clash with other angelfish. If you plan a community tank, pick tank mates with a comparable size and temperament, and provide hiding spots to retreat to. The order of introduction and the tank's size can also help reduce conflict.
5Not for Reef Tanks
Adults nip at hard corals, soft corals, giant clams and fan worms, so it is not suited to a reef tank. Keep it in a fish-focused aquarium with cave-like rockwork and live rock.
6Offer a Varied Diet
Large angelfish tend to be omnivorous, so combining foods of both animal and plant origin helps keep the diet balanced. Right after arrival, ask the breeder what the fish has been eating and start with the same food. Changes in appetite or feeding behavior can also be a useful sign of how the fish is doing.
7Acclimation on Arrival
After arrival, match the temperature and salinity and acclimate the fish slowly. Observing it in a separate quarantine tank before moving it to the main display makes it easier to avoid bringing illness into the tank. Check its skin and appetite every day, and act early if anything looks off.
