Why do my Everlasting Gobstopper Zoanthids lose their vivid ring colors under strong lights?

They can brown or wash out when PAR is too high or spectrum skews blue-heavy for long photoperiods. Aim for moderate PAR (80–150), shorten the peak photoperiod, and add a brief neutral-white window to maintain pigment balance. Keep nutrients measurable (NO3 5–15 ppm, PO4 0.03–0.1). Ramp light changes slowly over 2–3 weeks to avoid stress and color shifts.

How can I encourage tight, compact growth instead of long “stretchy” skirts?

Provide moderate, cross-flow that gently waves polyps without folding them over. Increase PAR gradually if polyps are reaching, and keep alkalinity and pH stable to support calcification of the base mat. Avoid chronic low nutrients, which causes shrinkage, and high organics, which promotes algae at the mat edge. Consistent, moderate conditions produce tighter skirts and denser colonies.

My colony stopped opening after adding new frags—what should I check beyond pests?

Consider chemical aggression. Run fresh activated carbon and increase water changes for a couple weeks. Ensure no nearby LPS sweepers or palys are contacting the mat at night. Verify flow isn’t blasting directly, and raise the colony slightly if sand is irritating skirts. If symptoms persist, try an isolation rack; many reopen within days once allelochemicals are reduced.

Are there telltale signs of zoa-specific predators on this morph, and how do I respond?

Look for bite marks on skirts, notches on discs, and egg spirals from zoa-eating nudibranchs under the mat. Inspect at night with a flashlight. Remove adults manually, scrape eggs, and perform scheduled dips (iodine or low-dose peroxide) over 2–3 weeks to break life cycles. Also watch for sundial snails and tiny spiders; both require manual removal and repeat checks.

Everlasting Gobstopper Zoanthids Coral

Zoanthids

Overview

Everlasting Gobstopper Zoanthids Coral shows bright orange centers with green skirts around each polyp. Zoanthus sp., a colonial soft polyp coral, forms mat-like clusters and does well under moderate light and low to moderate water flow. Primarily photosynthetic with symbiotic algae, it can also take occasional small particle or meaty foods to support growth and maintain color. It can spread quickly, so place on a separate rock island and keep space from slower-growing corals.

Care & Placement

Everlasting Gobstopper Zoanthids Coral (Zoanthus sp.) thrive under stable, nutrient-moderate reef conditions. Provide moderate light (PAR ~80–150); start lower and increase over 1–2 weeks to avoid bleaching. Aim for moderate, indirect flow that keeps detritus off the polyps without pinning them closed; this helps prevent film algae and bacterial issues. Target feed finely minced meaty foods or powdered coral foods 1–2× weekly to speed growth and deepen color, though they can subsist on light alone. Keep temperature 76–80°F, salinity 1.024–1.026 (refractometer), pH 8.1–8.4, alkalinity 8.0–9.5 dKH, calcium 400–450 ppm, magnesium 1250–1350 ppm, nitrate 2–10 ppm, phosphate 0.03–0.08 ppm. Test weekly and correct slowly; swings, especially in alkalinity and salinity, cause polyp shutdown.Place frags low to mid in the tank with moderate light and flow, then move as needed. Give 2–3 inches of space from slower growers; Zoanthus can spread and shade neighbors but are generally peaceful. Avoid direct contact with aggressive stingers. Dip new pieces to remove pests (zoa-eating nudibranchs, sundial snails), inspect for eggs, and quarantine if possible. Acclimate to light and flow gradually. If polyps stay closed, check for pests, adjust flow, verify nutrients aren’t bottomed out, and stabilize parameters; an iodine-based dip can help with bacterial “melt.” Handle with gloves and eye protection, as some zoanthids contain palytoxin. Troubleshoot color loss by easing light intensity slightly and restoring low but present nutrients.
