Fathead Anthias

Fathead Anthias (Serranocirrhitus latus) 🐠 Identity & Appearance Common names: Fathead Anthias, Sunburst Anthias, Hawkfish Anthias. Scientific name: Serranocirrhitus latus. Size: ~5 inches adult. Coloration: Gradient of orange‑red, pink, yellow, often with purple/blue facial accents. Heavy yellow/orange scale margins; translucent fins with blue or purple edging. Body shape: Deep‑bodied, “fat‑headed,” more hawkfish‑like than typical anthias. 🌍 Natural Habitat & Behavior Range: Western Pacific — Japan, Indonesia, Philippines, Papua New Guinea, Solomon Islands, Fiji, Tonga, Australia. Depth: Commonly 50–230 ft; prefers caves, overhangs, drop‑offs. Behavior: Solitary or paired; not a schooling anthias. Often perches on rock ledges like a hawkfish. Shy, secretive; stays near structure and shaded areas. Planktivore that waits for drifting zooplankton in moderate–strong current. 🧪 Aquarium Requirements Minimum tank: 55–75 gallons depending on source; 75+ gallons recommended for long‑term stability. Lighting: Prefers low to moderate light; deep‑water origin makes bright reef lighting stressful. Aquascape: Heavy rockwork, caves, ledges, shaded pockets. More hiding spots = more confidence and more visible behavior. Flow: Moderate to strong, mimicking deep reef slopes. Reef safety: Completely reef‑safe; ignores corals and inverts. Jumping: Known jumper — tight mesh lid recommended. 🍤 Diet & Feeding Type: Planktivore/carnivore. Foods: Frozen mysis, enriched brine, copepods, plankton blends, small pellets. Live foods (Artemia, copepods) help new arrivals begin feeding. Frequency: 2–3 small feedings daily; more forgiving than schooling anthias but still benefits from multiple feedings. 🧬 Social Structure & Compatibility Temperament: Peaceful, shy. Best kept: Single specimen or mated pair; small groups only in large tanks. Only one male per tank. Anthias are hermaphroditic — largest female can become male. Tankmates: Peaceful species (gobies, small wrasses, chromis). Avoid aggressive or fast, boisterous fish. 🩺 Acclimation & Hardiness Difficulty: Moderate/Intermediate. Why: Deep‑water origin → sensitive to bright light and stress. Often shy and slow to begin feeding. Needs stable, mature systems.
