Why is my ORA Pearlberry losing its pearly blue tips and looking washed out?

This coral needs strong, stable light (PAR ~300–450) with a strong blue/UV component. If tips fade, check for low PAR, aggressive light changes, or imbalances in nutrients and traces. Keep NO3 ~2–10 ppm, PO4 0.03–0.08 ppm, and potassium ~380–420 mg/L. Avoid ultra-low nutrients with high alkalinity; that combo bleaches tips. Light-acclimate slowly and maintain steady alkalinity (7.5–8.5 dKH).

How can I shape its growth—tabling or branching?

ORA Pearlberry (Acropora desalwii) encrusts first, then throws slender branches. Mount small frags horizontally on a flat plug or shelf rock to encourage multiple axial points and a mini-table form. Upright mounts favor a single dominant branch. Provide wide, open space, high, chaotic flow, and don’t crowd it—shade from neighbors will skew growth and color.

I’m seeing “burnt tips” and slow tissue loss—what’s the likely cause?

Common triggers are high alkalinity paired with very low nutrients, sudden PAR spikes, or pests like AEFW. First, stabilize parameters and raise nutrients slightly if near zero. Bring alk down to 7.5–8.5 dKH, increase flow, and check for pests (night inspection, dips). Run fresh carbon if soft corals are nearby to reduce chemical warfare. Frag ahead of recession if needed.

Polyp extension is poor on one side—could flow be the issue?

Yes. Laminar, one-directional blasts often cause tissue wear on the downstream side. Aim for strong, random turbulence that sweeps from multiple angles. Alternate pumps or use gyre/random modes. If PE improves at night, fish nipping may be involved—watch for dwarf angels or pecking wrasses. Ensure stable temp and pH, which also affect PE.

ORA Pearlberry Acropora Coral

Acropora

Overview

ORA Pearlberry Acropora Coral shows tightly spaced, upward-branching tips with pearly blue to purple highlights. Acropora desalwii is a small-polyp stony branching coral that prefers strong light and high, turbulent water flow. It is primarily photosynthetic with symbiotic algae but can benefit from occasional very fine planktonic foods, which may support growth and coloration. Place high on stable rockwork with space from aggressive neighbors, and keep parameters stable with low nutrients.

Care & Placement

ORA Pearlberry Acropora Coral (Acropora desalwii) thrives in bright light, strong random flow, and very stable water. Target 250–400 PAR, ramping up over 2–3 weeks to avoid bleaching; start lower or use screen/shading if coming from dimmer systems. Provide high, turbulent flow to keep polyps clean and prevent detritus buildup—alternate or gyre patterns work well. Mostly photosynthetic, but light broadcast feeding 1–2 times weekly with fine particulate foods (rotifers, reef snow, amino acids) can support color and growth. Keep nutrients low but not zero: nitrate 2–10 ppm, phosphate 0.02–0.08 ppm. Key parameters: temp 24–26°C (75–79°F), salinity 1.025–1.026, pH 8.1–8.4, alkalinity 8–9 dKH (avoid swings >0.3 dKH/day), calcium 420–460 ppm, magnesium 1300–1400 ppm. Test weekly (more often after changes), automate dosing as demand rises, and perform regular water changes.Place high on stable rock with space for branching—top third of the tank is best. Allow 2–3 inches from other SPS to prevent shading and 6+ inches from stinging LPS. Avoid aggressive neighbors and coral warfare; good fishmates include peaceful reef fish (watch nipping angels). Acclimate by temperature matching, dipping for pests (AEFW, red bugs), and securing the frag to avoid wobble. Troubleshooting: pale/bleach—reduce light or raise nutrients; browning—increase light or export; tissue recession—boost flow, check pests, and stabilize alkalinity; burnt tips—lower alkalinity or raise nutrients slightly. Regular PAR checks and consistent stability are the keys to success.
