Why did my Green Implosion Palythoa lose neon green and look browner over time?

Color shift usually tracks light spectrum and nutrients. Blue-heavy spectrum (420–460 nm) with moderate PAR restores fluorescence, while high nitrate/phosphate can deepen brown zooxanthellae. Too “ultra-clean” water may wash out color and shrink polyps. Stabilize alkalinity and trace (iodine/iron within normal reef ranges), add gentle flow to shed films, and avoid sudden spectrum or intensity changes—ramp adjustments over weeks.

How fast will it spread, and what’s the best way to contain it?

It creeps via a tough mat that can bridge small gaps and even adhere sand to colonize new rock. Use an isolated “island,” maintain a sand moat, and direct flow so fragments don’t drift. For edging control, lift and cut a strip of mat to break the growth line, or spot-apply kalk paste to the advancing edge. Siphon debris under the mat to prevent hidden die-off.

Is target feeding worthwhile, and how can I tell it’s helping?

Yes—small meaty foods (mysis slurry, roe, fine pellets) and occasional amino acids can boost growth. Turn off flow, feed lightly, restore flow after a few minutes. Signs of benefit: thicker oral discs, quicker polyp reopening after lights on, faster mat extension, and deeper green speckling. If you see prolonged slime, slower reopening, or rising nutrients, reduce frequency or portion size.

What’s a safe propagation method for Palythoa sp., and how do I handle toxin risk?

Wear gloves, eye protection, and a mask; work in strong ventilation. Cut the mat between polyps with a fresh blade; underwater cutting reduces aerosol. Rinse frags, iodine dip, and place in moderate flow for healing. Run fresh carbon and avoid hot water or steam near tissue. Light-acclimate frags—start lower and raise intensity over a week to prevent bleaching.

TSA Green Implosion Palythoa Coral

Beginner Corals Zoanthids Soft Coral

Overview

Green Implosion Palythoa Coral features dense mats of button-like polyps with bright green centers. Palythoa sp. is a soft colonial zoanthid, thriving under moderate light and low to moderate water flow. It is photosynthetic via symbiotic algae but accepts small meaty foods, which can speed growth and deepen color. Place on an island rock to control spreading, and handle with care due to possible palytoxin; keep space from stinging neighbors.

Care & Placement

Green Implosion Palythoa Coral (Palythoa sp.) thrives in stable, nutrient-moderate systems with moderate light and flow. Place colonies low to mid in the tank under 50–150 PAR; acclimate to light by starting shaded and increasing exposure over 1–2 weeks to avoid bleaching. Provide moderate, random flow to keep polyps clean and prevent detritus buildup without pinning them closed. Feed is optional but beneficial: target-feed finely chopped marine foods or coral foods 1–2 times weekly; avoid overfeeding. Maintain temperature 76–79°F (24–26°C), pH 8.0–8.4, salinity 1.025–1.026, calcium 400–450 ppm, alkalinity 8–9.5 dKH, magnesium 1250–1350 ppm, nitrate 2–10 ppm, and phosphate 0.03–0.10 ppm. Test weekly and prioritize stability—rapid alkalinity swings and sudden light changes trigger recession. These polyps can spread quickly; mount on an isolated rock or keep 2–3 inches from neighbors to prevent overgrowth. Compatible with most peaceful corals and fish, but avoid aggressive stingers and nippers. Dip new arrivals to exclude pests (e.g., sundial snails, nudibranchs). Use drip acclimation for 30–45 minutes, then place in lower light. Signs of trouble: stretching = low light/flow; persistent closure = irritation, pests, or unstable parameters; paling = too much light or low nutrients. Safety: wear gloves and eye protection when handling or fragging, and never expose to hot water or steam due to palytoxin risk.
