Personifer Angel

Aquarium Requirements

Minimum Tank Size: 400–500 litres (105–130 US gallons)

Temperature: 24–27 °C (75–81 °F)

pH: 8.1–8.4

Specific Gravity (Salinity): 1.020–1.025

Alkalinity: 8–12 dKH

Ammonia & Nitrite: 0 ppm

Nitrate:< 10 ppm

Aquascape:
Provide a mature reef environment with ample live rock, caves, and crevices for hiding. Moderate water flow and open mid-water swimming areas are essential. Juveniles are especially shy and benefit from shaded areas during acclimation.

Stable water conditions and excellent oxygenation are critical for the health and coloration of this species.

Diet and Feeding

The Personifier Angelfish is omnivorous, naturally feeding on sponges, tunicates, algae, and small invertebrates.

Recommended Foods:

• Sponge- and algae-enriched frozen angelfish diets

• Mysis shrimp, brine shrimp, and finely chopped seafood (clam, scallop, squid)

• Spirulina- or algae-based flakes or pellets

• Grazing on live rock to mimic natural foraging behavior

Feed 2–3 times daily in small portions. Nutritional variety and sponge supplementation are critical to prevent malnutrition and maintain vibrant coloration.

Temperament and Compatibility

This species is peaceful but shy, often retreating to crevices when stressed.

Suitable Tankmates:

• Peaceful species such as tangs, wrasses, butterflyfish, and clownfish

• Other angelfish in very large tanks where territories can be established

Avoid:

• Aggressive, territorial species that could outcompete or harass this angelfish

Adults generally become more confident once acclimated, but juveniles remain reclusive and need protection from aggressive tankmates.

Reef Compatibility

✅ Generally Reef Safe (with caution)

The Personifier Angelfish is mostly reef compatible if provided with a nutritionally adequate diet. Natural grazing habits may occasionally target sessile invertebrates if sponge-based foods are insufficient.

Best Practices:

• Introduce into a mature reef aquarium with abundant live rock

• Supplement with sponge- and algae-rich diets to minimize coral or invertebrate nipping

• Provide ample hiding spaces for juveniles

Additional Information

Maximum Size: 25–28 cm (10–11 inches)

Lifespan: 12–15 years with proper care

Difficulty Level: Advanced

Natural Behavior: Semi-shy, mid-water grazer; juveniles often secretive, adults more confident

Origin: Western Pacific – northern Australian reefs

Coloration: Dark body with contrasting fin highlights; unique facial mask-like markings

Summary

The Personifier Angelfish (Chaetodontoplus meredithi) is a rare, mid-water reef angelfish suitable for experienced marine aquarists. Juveniles require ample hiding spaces, stable water parameters, and a sponge- and algae-rich diet. With proper care, they mature into confident, vibrantly colored adults that are mostly reef safe and maintain natural grazing behaviors for over a decade.
