Griffis Angel

Aquarium Requirements

Minimum Tank Size: 475 litres (125 US gallons) or larger

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:< 20 ppm (preferably < 10 ppm)

Aquascape:
Provide a spacious, mature aquarium with extensive live rock arranged to form caves, ledges, and shaded areas for refuge. This species naturally inhabits deeper reefs, so subdued or indirect lighting is appreciated.

Ensure ample open swimming space in addition to rockwork. Strong, well-oxygenated water flow and pristine water conditions are essential for long-term health. A powerful protein skimmer and efficient biological filtration are strongly recommended.

Diet and Feeding

The Griffis Angelfish is an omnivorous sponge and tunicate grazer, feeding on sponges, tunicates, and detritus in the wild. In captivity, it adapts well to prepared foods if offered a nutritionally varied and sponge-enriched diet.

Recommended Foods:

• Frozen angelfish formulas containing marine sponge material

• Finely chopped fresh seafood (clam, shrimp, scallop, squid)

• Enriched mysis and brine shrimp

• Spirulina- and algae-based flakes or pellets

• Dried seaweed (nori) clipped to rockwork or feeding clips

Feed 2–3 small meals daily. Supplementing with sponge-based preparations ensures optimal nutrition and vibrant coloration. Allowing natural algal and sponge growth on live rock encourages grazing behavior.

Temperament and Compatibility

The Griffis Angelfish is generally peaceful to semi-aggressive, displaying mild territoriality once established but coexisting well with other non-aggressive species. It is less aggressive than many large angelfish, making it an excellent choice for community or FOWLR systems.

Suitable Tankmates:

• Peaceful to moderately assertive species such as tangs, butterflyfish, wrasses, anthias, and larger reef-safe community fish

• Other Apolemichthys or large angelfish only in very large systems (over 700 L / 185 gallons) with distinct territories

Avoid:

• Very aggressive species (large triggers, groupers, or overly dominant angels)

• Very small or timid fish that may be intimidated by its size

If adding multiple angels, introduce the Griffis Angelfish last to minimize territorial conflict.

Reef Compatibility

⚠️ Reef Safe with Caution

Like most Apolemichthys angels, the Griffis Angelfish may occasionally nip at:

• LPS corals (especially fleshy species such as Acanthophyllia or Trachyphyllia)

• Zoanthids and soft corals

• Clam mantles

However, individuals vary, and many aquarists report success in mixed or SPS-dominant reef systems when the fish is well-fed and introduced to an established aquarium. A mature, stable environment with consistent feeding greatly reduces coral interest.

Additional Information

Maximum Size: Up to 25 cm (10 inches)
Lifespan: 10–15 years in captivity with excellent care
Difficulty Level: Advanced
Natural Behavior: Slow, deliberate swimmer; grazes on sponge-encrusted surfaces; prefers shaded and low-light areas reminiscent of deeper reefs
Origin: Central and Western Pacific — Marshall Islands, Nauru, Palau, Kiribati

Sexual Dimorphism: Minimal; males and females are visually similar. Some sexual distinction may occur in size and fin shape in mature pairs.

Summary

The Griffis Angelfish (Apolemichthys griffisi) is a rare and majestic marine angelfish prized for its sophisticated appearance, peaceful temperament, and deepwater origins. With its elegant black and silver contrast and composed demeanor, it serves as a stunning focal point in large, well-maintained aquariums.

Thriving best in mature, stable systems with ample rockwork, sponge-based nutrition, and excellent water quality, this species rewards dedicated aquarists with years of beauty and calm presence. Though rare and commanding a premium price, the Griffis Angelfish is a truly exceptional addition for discerning marine fish enthusiasts.
