False Personifer Angelfish (Chaetodontoplus Meredithi) saltwater aquarium fish portrait

The False Personifer Angelfish, Chaetodontoplus meredithi, is a striking western Pacific species also known as Meredith's Angelfish, the Queensland Yellowtail Angelfish, and the Bluemask Angelfish. The body is deep black, offset by a predominantly blue head speckled with yellow and a clean yellow tail, while the dorsal and anal fins carry margins that shade from blue to yellow. Adults reach roughly 12 inches, giving mature specimens genuine presence in a large display. The species ranges from Queensland south into New South Wales and out to Lord Howe Island, where it patrols coastal and inner reefs rich in sponges and sea whips at depths from about 20 feet to well beyond 150 feet, usually in pairs or small harems.

Adult housing should begin at 150 gallons and larger is better for a fish of this size and territorial nature. Build the layout around a substantial volume of mature live rock arranged into caves, crevices, and overhangs so the fish has multiple retreats and clear swimming lanes between them. A fish-only system with live rock suits this angelfish far better than a coral display, since its grazing habits put sessile invertebrates at risk. Stocking order matters: add smaller and more docile fish first, save larger or assertive species for last, avoid tankmates with similar coloration, and make sure resident fish are well fed before a new arrival goes in. Care level is moderate, so stable conditions and an established tank pay dividends.

On the reef, this angelfish feeds primarily on sponges, algae, tunicates, and small crustaceans, which makes a sponge component important in captivity rather than optional. Build the captive menu around prepared angelfish formulas high in sponge matter, then round it out with fortified brine shrimp, mysis shrimp, and chopped clams for protein. Marine algae in the form of freeze-dried sheets, spirulina, and nori supplies the vegetable portion this omnivore grazes on throughout the day.

Newly introduced fish benefit from several small feedings spread across the day, which encourages a shy specimen to begin eating and shortens the acclimation period. Once the fish is settled and feeding confidently, twice-daily feedings are appropriate. Watch that a dominant tankmate is not intercepting food, and offer algae sheets on a clip so the angelfish can browse at its own pace.

Expect a reserved fish for the first days or weeks after introduction, tucked into caves and crevices and emerging only briefly. As it gains confidence, it becomes considerably more outgoing and will claim a territory within the rockwork. The temperament is semi-aggressive, and a settled adult may press its claim against newcomers or fish that occupy similar space. Housing two members of the genus Chaetodontoplus together is not advisable, though pairing this angelfish with a different angelfish genus can work in a sufficiently large system; Apolemichthys species tend to be comparatively mild companions.

This species is not reef safe. It nips clam mantles, picks at LPS and SPS coral polyps, and will sample some soft corals, so ornamental corals and tridacnid clams should be kept out of the display. Small crustaceans also fall within its natural prey range. The practical solution is a fish-only aquarium furnished with abundant mature live rock, which satisfies the fish's need for cover and grazing surfaces without putting valuable invertebrates at risk.

FAQ

Frequently Asked Questions

About the False Personifer Angelfish

  • Is the False Personifer Angelfish reef safe?
    No. It nips clam mantles, LPS and SPS coral polyps, and some soft corals, so it is best housed in a fish-only aquarium with plenty of mature live rock.
  • How large should the aquarium be for an adult?
    Plan on a minimum of 150 gallons, furnished with abundant mature live rock arranged into caves, crevices, and overhangs for security.
  • Can this angelfish be kept with other angelfish?
    Two Chaetodontoplus species should not share a tank, but a different angelfish genus can work in a large system. Apolemichthys species are noted as less aggressive companions.
