Why does my Dragon Spirit Favia change color under different lighting, and how can I keep the neon “dragon scale” look?

Favia favus shifts pigment density with spectrum and PAR. Intense blue-heavy light boosts fluorescence but too much PAR (>200–250) can wash patterns or brown the colony. Aim for moderate PAR (100–180), strong blues (420–470 nm), and stable low nutrients with consistent nitrate (5–15 ppm) and phosphate (0.03–0.08 ppm). Rotate the colony monthly to prevent shading stripes and maintain even coloration.

My Favia sends out long sweepers at night—how far should I space it, and can I “train” aggression?

Give 4–6 inches minimum; some colonies deploy 3–5 inch sweepers when flow ramps or during spot feeding. To reduce stings, avoid blasting flow, schedule target feeding after ambient food is removed, and keep rival LPS (acans, chalices) upstream. Consistent feeding lessens territorial grabs. If neighbors must be close, use a rubble barrier to deflect tentacles.

What’s the safest way to frag a Dragon Spirit Favia without losing the pattern or causing recession?

Cut between corallites along the skeletal valleys using a diamond saw; avoid splitting a single polyp. Dip frags in iodine-based solutions, then place in low–moderate light and gentle, indirect flow. Feed small particulate foods 2–3 times weekly to speed recovery. Keep alk and calcium stable to prevent dieback. Allow at least 4–6 weeks for encrustment before moving.

The colony has slow tissue recession from the base—what’s the likely cause and best rescue plan?

Common triggers are chronic shading, vermetid irritation, or bacterial infection after alk swings. Inspect and remove vermetids, increase indirect flow to deter detritus, and frag 0.25–0.5 inch into healthy skeleton past the recession line. Perform an iodine dip, stabilize alk (7.8–8.6 dKH) and temperature, and reduce PAR by 15–20% for two weeks. Nighttime target feeding supports regrowth.

Dragon Spirit Favia Coral

Overview

Dragon Spirit Favia Coral displays polygonal, maze-like corallites with distinct, contrasting mouths. Favia favus is a large polyp stony brain coral with a domed to encrusting skeleton, preferring moderate light and low to moderate water flow. It is photosynthetic via symbiotic algae but benefits from occasional small meaty feedings at night to support growth and maintain coloration. Give it space from other corals due to long nighttime sweepers and place on stable rockwork with room to expand.

Care & Placement

Dragon Spirit Favia Coral (Favia favus) thrives with stable, moderate conditions. Provide moderate PAR (75–150) under blue-leaning spectrum; start in lower light and increase slowly to avoid bleaching. Aim for moderate, indirect flow to keep tissue clean and prevent detritus buildup without lifting flesh from the skeleton. Target feed small meaty foods (mysis, reef roe, finely chopped seafood) 1–2 times weekly after lights dim, when feeding tentacles extend; this supports growth and color. Keep temperature 24–26°C (75–79°F), pH 8.1–8.4, salinity 1.025–1.026, calcium 400–450 ppm, alkalinity 8.0–9.5 dKH, magnesium 1280–1380 ppm, nitrate 2–10 ppm, phosphate 0.03–0.08 ppm. Test weekly and log results; watch for swings, especially in alkalinity, which can trigger tissue recession.Place low to mid in the tank on stable rock with 4–6 inches clearance from neighbors; Favia extends long night sweepers and will sting. Avoid direct flow from powerheads and keep edges off sand to prevent abrasion. This coral is semi‑aggressive but coexists with other LPS if spaced well; run activated carbon and perform regular water changes to reduce chemical warfare. Acclimate with a slow drip and light acclimation (shade or reduced intensity for 1–2 weeks). Dip new pieces to limit pests. If you see paling or retraction, lower light, check temperature and alkalinity, and increase feeding. For recession, inspect for pests, stabilize parameters, and trim dead skeleton to clean margins, then improve flow and cleanliness around the colony.
