Introduction to Masked Angelfish (Genicanthus personatus)
Masked Angelfish is a striking marine animal native to the Hawaiian islands. It boasts a pearly white body and has a distinctive dark “mask” around the eyes in the female or vivid yellow-orange accents in the male depending on the maturity and sex.
The Japanese Masked Swallowtail Angelfish (Another name of Masked Angelfish) is not unlike normal reef angelfish who live in shallow water. They are typically found at a considerable depth requiring cool water, very clean and a mature aquarium to thrive. Given its rarity and the technical demands required for its care, this species is suited for experienced marine aquarists.
Masked Angelfish size
The size of the Masked angelfish is 20-25 cm (8-10 inches) in length. Its size demands adequate swimming space and vertical room.
Lifespan of Masked Angelfish
They can live up to 10 years or more under optimum conditions. However, in many hobby setups the lifespan may be shorter if water parameters and husbandry aren’t optimal.
Masked Angelfish Price
The Masked angelfish hawaii is extremely rare. This is why it comes with a very high price. The Masked Angelfish price in India is ₹10 to 20 lakhs or more.
Best Tank Mates
- Peaceful mid-to-large sized fish species that occupy different zones (e.g., some tangs, butterflyfish)
- Other semi-aggressive but non-coral-nipping species
- Wrasses and gobies that keep to the substrate and are not direct competitors
Avoid Pairing With
- Very small schooling fish that may be eaten or harassed
- Highly territorial or aggressive species (large groupers, triggers)
- Invertebrates or corals if you cannot guarantee reef-safe behaviour (although the Masked Angelfish is more reef-safe than many, caution is warranted)
