ORA Frogskin Acropora Coral

ORA Frogskin Acropora Coral

Acropora

Overview

ORA Frogskin Acropora Coral shows a knobby, textured branching form with small polyps and contrasting tips. Classified as Acropora sp., it is a small-polyp stony branching coral that prefers strong, turbulent flow and moderate to high light. It relies on symbiotic algae for most nutrition but can benefit from occasional fine plankton or amino-rich feeds, supporting faster growth and stable coloration. Place high on rockwork with good flow, allow space from stinging neighbors, and acclimate to brighter light gradually.

Care & Placement

ORA Frogskin Acropora Coral (Acropora sp.) thrives with strong, stable conditions and consistent maintenance. Provide high light at 250–350 PAR (acclimate from lower light over 2–3 weeks to avoid bleaching), and strong, random flow to keep tissue clean and prevent detritus buildup; aim pumps across the colony, not directly at one spot. Keep temperature 75–78°F (24–26°C), salinity 1.025–1.026, pH 8.1–8.4, alkalinity 8.0–9.5 dKH (avoid daily swings), calcium 420–460 ppm, magnesium 1300–1400 ppm, nitrate 2–10 ppm, and phosphate 0.03–0.08 ppm. Test alkalinity and nutrients 2–3 times weekly until stable; use an auto top-off for salinity and consider periodic ICP testing. Place mid-to-high in the tank with clear access to flow and light; mount on a secure plug or rock ledge so branches can grow upward without shading the base. Allow 2–4 inches of space from neighbors; avoid proximity to aggressive LPS and fast-spreading encrusters. Feed small-particle foods (reef roids, oyster eggs) or amino acids 1–2x per week as light broadcast; do not overfeed. Quarantine and dip to exclude pests (AEFW, red bugs). Drip acclimate 30–60 minutes, temperature match, and light acclimate. Watch for pale tissue (too much light, low nutrients) or recession from the base (alk swings, pests, poor flow). Maintain strong export, steady parameters, and avoid frequent relocation.

FAQ

Frequently Asked Questions

About the ORA Frogskin Acropora Coral

  • How does the “frogskin” texture affect placement and flow for ORA Frogskin Acropora?
    Its smoother coenosteum and knobby branchlets trap less detritus than spiky Acros, but it still needs strong, randomized flow to keep tissue clean. It typically encrusts wide before sending up nubs, so plan space for lateral spread. Aim PAR 250–400 with alternating flow to prevent base shadowing; rotate or prune to avoid self-shade that can lead to slow tissue loss at the base.
  • Why does mine shift from lime green to tan or develop purple tips only under blues?
    Color swings reflect spectrum and nutrient balance. High blue with stable NO3 2–10 ppm and PO4 0.03–0.08 supports green body with violet/blue tips. Warmer whites or elevated nutrients can mute green; ultra-low nutrients can wash out color. To reverse browning: stabilize alkalinity (8–9 dKH), reduce organics, increase PAR gradually, and maintain moderate nutrients rather than driving them to zero.
  • What causes “burnt tips” or base STN on this coral, and how do I correct it?
    Burnt/bald tips often follow alkalinity spikes or rapid nutrient drops under high light; base STN is frequently from self-shadowing and low flow around the encrusted skirt. Fix by stabilizing alk changes to <0.2 dKH/day, slightly raising nutrients if stripped, adding more random flow across the base, and pruning or repositioning to open light channels. Avoid major light increases without matching nutrient/alk stability.
  • Are pests harder to spot on Frogskin, and what’s the best detection routine?
    Yes—its smoother tissue can hide early AEFW bites and red bugs. Quarantine all Acropora. Inspect at night with a flashlight for uneven polyp extension and pale bite arcs. Use weekly turkey-baster blasts to dislodge flatworms for visual confirmation. Dip frags (e.g., Bayer/iodine per label) on intake and after any new addition; consider a 4–6 week observation with periodic dips before moving to the display.
