Why do my God of War zoas lose their fiery red/orange skirts under higher light?

They can brown or shift under intense white or very high PAR. Aim for moderate PAR (80–150) with blue-heavy spectrum to keep saturation. Maintain stable nutrients (NO3 5–15 ppm, PO4 0.03–0.1 ppm); ultra-low nutrients wash out color. Avoid sudden light increases; ramp over 1–2 weeks. Iron/iodine dosing helps only if tested and deficient.

These polyps spread fast—how do I keep God of War from overrunning nearby corals?

They mat across rock and can shade slower encrusters. Place them on an isolated “island” rock or use sand gaps. Trim the mat edge monthly with a scalpel and siphon fragments. Maintain moderate, cross-flow to prevent detritus buildup that fuels faster creep. Keep a 2–3 inch buffer from sensitive SPS and low-growing LPS.

Do God of War zoas benefit from feeding, or is light enough?

They photosynthesize well but respond to occasional fine foods (reef roids, cyclops, rotifers) 1–2x weekly. Target lightly; overfeeding can cause film bacteria and closed polyps. Feed with pumps off for 10–15 minutes, then restore flow to clear leftovers. Watch for fuller skirts and faster matting as signs of positive response.

My colony is “pouting” or melting—what uncommon causes should I check?

Inspect at night for zoa-eating nudibranchs, sundial snails, and spiders; remove manually and dip (iodine or peroxide 1–2 mL 3% per 100 mL, 2–3 minutes). Check for vermetid snail mucus irritating skirts. Correct low flow that traps detritus between polyps. Stabilize alk 8–9.5 dKH and avoid rapid nutrient swings; sudden ULN shifts often trigger receding mats.

God of War Zoanthids Coral

Zoanthids

Overview

God of War Zoanthids Coral features bright red to orange centers with contrasting skirts on small button polyps. Zoanthus sp., a soft colonial polyp, does well with moderate light and low to moderate, steady water flow. Primarily photosynthetic with symbiotic algae, it can take occasional small particulate foods to support growth and color. Place on an isolated rock to control spreading and avoid contact with delicate neighbors; handle carefully, as some zoanthids may contain toxins.

Care & Placement

God of War Zoanthids Coral (Zoanthus sp.) thrive in stable, reef-safe systems with moderate light and moderate, indirect flow. Place colonies low to mid in the tank and acclimate to light slowly using reduced intensity or screen layers over 1–2 weeks to prevent bleaching. Provide flow that keeps polyps gently swaying and prevents detritus buildup; avoid blasting the polyps directly. They are photosynthetic but benefit from occasional small-particle foods (reef roids, marine snow) and amino acids 1–2x weekly for color and growth. Target water parameters: temperature 24–26°C (75–79°F), salinity 1.024–1.026, pH 8.1–8.4, alkalinity 8.0–9.5 dKH, calcium 400–450 ppm, magnesium 1250–1350 ppm, nitrate 2–10 ppm, phosphate 0.03–0.10 ppm. Test weekly, maintain stability, and avoid rapid swings, which often cause closing or recession.Give them space from aggressive LPS with long sweeper tentacles and from fast-growing soft corals. Zoanthids can spread; mount on a separate rock “island” to control growth and keep 2–3 inches from neighbors. Compatibility is generally good with peaceful corals and reef-safe fish/inverts. Dip new frags to exclude pests (zoa-eating nudibranchs, sundial snails) and handle with gloves and eye protection due to palytoxin risk. Drip acclimate 30–45 minutes. Troubleshooting: stretching indicates low light or flow; persistent closing suggests pests, unstable parameters, or irritation from algae/film—adjust flow, clean gently, and recheck tests. If color washes out, reduce light intensity and improve nutrient balance rather than running ultra-low nutrients.
