Why do my OG Bizarro Zoas lose their pop under strong whites even though PAR is fine?

This morph shows best contrast under blue-heavy spectrum. Intense white light can wash pigments, causing “flat” colors despite acceptable PAR. Shift spectrum toward 420–470 nm, reduce whites, and stabilize nutrients (nitrate 5–15 ppm, phosphate 0.03–0.1 ppm). Trace balance matters; mild iron/iodine replenishment can help, but avoid overdosing. Expect color to return over 2–4 weeks.

The colony is growing but polyps stay small and skirts are short—what’s the likely cause?

Often flow or chemistry. OG Bizarro tends to extend skirts in brisk, non-laminar flow; too little flow leads to compact polyps and detritus buildup. Also check alkalinity stability (keep daily swing <0.3 dKH) and avoid ultra-low nutrients. Slightly elevated nitrate often restores fuller extension within days.

Can I isolate OG Bizarro to prevent it from overrunning rocks without stunting growth?

Yes—use a “zoa island” with a rubble moat. Place the frag on a small, freestanding rock surrounded by coarse rubble or bare sand, then siphon any runners. Trim mats at the perimeter with a sharp scalpel and immediately dip the cut edge in iodine. This maintains vigor while controlling spread.

What’s the safest dip protocol for this morph when dealing with pests like sundial snails or zoa-eating nudibranchs?

Start with a gentle iodine-based dip (per label) for 5–7 minutes, swish vigorously, then inspect for egg spirals and manually remove them. Repeat every 4–5 days for two weeks to break life cycles. Avoid harsh peroxide concentrations; this morph can sulk. Rinse in clean tank water before returning.

Zoanthids

Overview

OG Bizarro Zoanthids Coral features small button-like polyps with contrasting centers and skirts. Zoanthus sp. is a soft, colonial mat-forming coral that spreads over rock; it does well under moderate light and low to moderate water flow. It is photosynthetic via symbiotic algae, but occasional small particulate foods can boost growth and maintain color. Place on an isolated rock to control spread, and handle with care, as some zoanthids can contain toxins.

Care & Placement

OG Bizarro Zoanthids Coral (Zoanthus sp.) thrives with stable, moderate conditions. Provide moderate light at 80–150 PAR; start lower and increase gradually to avoid bleaching and to bring out color. Use moderate, random flow to keep detritus from settling without blasting the polyps; too much flow makes them stay closed. Target feed 1–2x weekly with fine foods (rotifers, reef roids, small mysis slurry) and occasional amino acids; they will grow without feeding but respond with fuller polyp extension. Keep temperature 75–78°F (24–26°C), salinity 1.025–1.026, pH 8.1–8.4, alkalinity 8.0–9.5 dKH, calcium 400–450 ppm, magnesium 1250–1350 ppm, nitrate 2–10 ppm, phosphate 0.03–0.08 ppm. Test weekly; use a refractometer for salinity and keep alkalinity swings minimal. Perform 10–15% water changes every 1–2 weeks.Place frags low to mid in the tank on an isolated rock “island” to manage spreading. Leave 2–3 inches from neighbors; they are generally peaceful but can overgrow slower corals, and aggressive LPS with long sweepers can sting them. Acclimate by dripping 20–30 minutes, then light-acclimate with reduced intensity or shade for 1–2 weeks. Common issues: bleaching from too much light too fast, recession from unstable alk or ultra-low nutrients, closed polyps from pests (zoa-eating nudibranchs, sundial snails) or excessive flow. Inspect and dip new pieces; quarantine if possible. Handle with gloves and eye protection, avoid cuts, and never scrub or frag near your face. Stability and clean, oxygenated flow are the keys to steady growth.
