How do I maintain the signature colors of RRC Wonderland Acropora under LEDs?

Target 300–450 PAR with a blue-heavy spectrum (14–20K look), and acclimate gradually to avoid washing out pigments. Keep nutrients modest, not zero (NO3 2–10 ppm, PO4 0.02–0.08), and hold alkalinity stable (7.5–8.5 dKH). Color often improves with consistent potassium, iodine, and iron; verify via ICP tests. Excess white light or rapid alk swings commonly shift it toward dull greens or browns.

My Wonderland is paling at the base—what’s the likely cause and fix?

Often it’s self-shading plus low flow around the skeleton, leading to tissue recession. Increase random, high flow, slightly adjust angle of light, and trim overshadowing branches. Check for alk instability and bacterial stress; a targeted iodine dip can help if tissue loss is active. Keep PO4 detectable to prevent tissue thinning. Avoid drastic light increases, which can accelerate recession at shaded areas.

What growth pattern should I expect, and how should I plan placement?

Wonderland tends to branch and plate outward, forming a canopy that shades its base and nearby corals. Mount it on a pedestal or higher rock with at least 3–4 inches of clearance for future spread. Encourage upward, open growth with cross-flow to limit detritus. Expect rapid encrustment before vertical push; give it a stable plug/rock junction so the base can thicken and resist breakage.

Are there pests it’s especially sensitive to, and how do I catch them early?

Watch for Acropora-eating flatworms (AEFW) and red bugs. AEFW leave crescent bite marks and beige egg clusters under branches; blast with a baster and inspect at night with a flashlight. Red bugs reduce polyp extension and vibrance. Quarantine new frags, use targeted dips, and consider a pest-hunting wrasse. Maintain steady nutrients; stressed Wonderland tissues attract pests and mask early signs.

RRC Wonderland Acropora Coral

Acropora

Overview

RRC Wonderland Acropora Coral displays tight, branching growth with contrasting polyp tips. Classified as Acropora sp., it is a small-polyp stony branching coral that prefers strong light and high, turbulent water flow. It relies mainly on symbiotic algae for energy but benefits from occasional feeding of fine particulate foods, which can support growth and coloration. Place high on stable rockwork with space from aggressive corals, and keep water conditions very stable.

Care & Placement

RRC Wonderland Acropora Coral (Acropora sp.) thrives under bright light and strong, random flow. Target 250–400 PAR with gradual light acclimation (use screen layers or start lower and raise the coral weekly). Provide turbulent flow that keeps polyps moving and prevents detritus settling, but avoid a constant jet on the tissue. Keep temperature 75–78°F (24–26°C), pH 8.1–8.4, salinity 1.025–1.026, calcium 420–460 ppm, alkalinity 7.5–9 dKH (very stable), magnesium 1280–1380 ppm, nitrate 2–10 ppm, and phosphate 0.02–0.08 ppm. This coral is sensitive to rapid swings, especially in alkalinity and temperature. Feed very small foods (reef roids, rotifers) or amino acids 1–2 times weekly with pumps off for 10–15 minutes; do not overfeed.Place frags in the upper third of the tank on a stable mount with room for upward and outward growth. Give at least 3–4 inches clearance from other corals; avoid stinging LPS and leathers that release chemicals. Peaceful toward neighbors but fast-growing; it can shade slower species. Dip and quarantine new frags, inspect for pests (AEFW, red bugs), and stabilize before moving them higher. Maintain export and stability via skimming, auto top-off, and consistent dosing; test alkalinity, calcium, and magnesium several times per week at first. Troubleshooting: paling or bleaching suggests too much light or too little nutrients; browning points to low light or excess nutrients; recession often follows parameter swings or pests—correct stability, increase flow, and treat if needed.
