Cinnamon Palythoa (AC)
Warm copper and cream polyps — the earth tone your reef is missing.
Cinnamon Palythoa brings a warm copper-to-cream gradient that contrasts beautifully against the greens and blues that dominate most reef displays. The polyps extend fully in moderate flow and encrust steadily across open rock. Aquacultured, tank-adapted, and pest-free — sold by the polyp so you can build out the exact colony size you want.

What it needs to thrive
- Lighting
- Low to moderate — 60–120 PAR.
- Flow
- Moderate to strong for full polyp extension.
- Feeding
- Photosynthetic. Fine planktonic foods weekly speed encrusting.
- Temperament
- Peaceful, non-stinging, spreads readily across open rock.
- Difficulty
- Beginner
- Ideal Tank Size
- 10 gallons and up.
- Water Parameters
- SG 1.025 · Temp 78°F · Alk 8.0–9.0 dKH · Ca 420–440 ppm · Mg 1350–1400 ppm · NO₃ 2–10 ppm · PO₄ 0.03–0.10 ppm
Mid to upper rockwork or overhangs. Isolate on its own rock to control spread.
Non-stinging but invasive. Palythoa will creep across rock and overtake slower neighbors. Mount on an isolated rock or a raised ledge with a clear gap if you want to control the spread. Always wear gloves and eye protection when handling — palythoa can carry palytoxin.
Quarantine, dip, and acclimation
Quarantine
Hold all new fish in a bare-bottom 10–20 gallon QT for a minimum of 4 weeks. Observe for flashing, clamped fins, white spots, or breathing changes. Treat preventatively with copper (1.75–2.5 ppm chelated) or tank-transfer method for ich, plus a praziquantel course for flukes. Invertebrates and corals skip QT but go through dip and observation instead.
Recommended coral dip
For every new coral: a 5–10 minute bath in your reef-safe dip of choice (Bayer Complete, CoralRx, or Reef Primer) following label dosage, followed by two clean saltwater rinses. Inspect plugs and bases for flatworms, pyramid snails, and eggs — remove or refrag onto clean plugs before placing in display.
Acclimation
Float sealed bags in your QT or display for 15 minutes to match temperature. Then drip acclimate at 2–4 drops per second for 45–60 minutes until volume has tripled. Net livestock into the tank — never pour shipping water in. Dim the lights for the first 24 hours to reduce stress.
