About this fish
About this fish
The Flag Fin Angel (Apolemichthys trimaculatus) is a saltwater angelfish for the home marine aquarium. It’s typically added as a centerpiece fish because angelfish are known for bold, eye-catching patterns that can change as they grow. In practice, it benefits from an established tank with live rock where it can explore and graze, and it’s a good choice for aquarists who can provide a stable marine environment and careful selection of tankmates.
Features:
- Showy marine angelfish with striking patterning that may shift as it matures
- Thrives in aquariums with plenty of swimming space and live rock for natural grazing
- Often benefits from a varied menu, including quality frozen foods and algae
- May pick at corals and clam mantles, so it’s important to research reef compatibility before adding
- Best kept as the only angelfish in smaller setups; additional angelfish require a very large system to reduce aggression
- Arrives stress-sensitive—acclimate slowly and give it a quiet area to settle in before introducing other changes
