GB Fury Acropora Coral

GB Fury Acropora Coral

SPS Acropora

Overview

GB Fury Acropora Coral displays tightly spaced, upward-branching tips with contrasting axial and radial corallites. Acropora tenuis is a small-polyp stony branching coral that prefers strong lighting and high, turbulent water flow. It is primarily photosynthetic through symbiotic algae but benefits from occasional microplankton or amino-rich foods, which can support growth and color stability. Place high on rockwork with ample space from aggressive neighbors, and maintain stable alkalinity and low nutrients to avoid tissue recession.

Care & Placement

GB Fury Acropora Coral (Acropora tenuis) thrives under bright, stable conditions with strong, random flow. Target 250–350 PAR using quality LEDs or T5/LED hybrids, and ramp intensity over 1–2 weeks to prevent bleaching. Provide vigorous, turbulent movement (gyres or alternating powerheads) so polyps sway without a harsh, constant blast; this keeps detritus off the branches and promotes gas exchange. Maintain temperature 75–78°F (24–26°C), salinity 1.025–1.026, pH 8.1–8.4, alkalinity 8–9 dKH (stable), calcium 420–460 ppm, magnesium 1300–1400 ppm, nitrate 2–10 ppm, and phosphate 0.03–0.08 ppm. Feed sparingly 1–3x weekly with fine particulate foods and occasional amino acids; overfeeding can raise nutrients too quickly. Test weekly (more often after changes), use an ATO for salinity, and consider two-part or kalkwasser to hold Ca/Alk as growth accelerates.Place frags high to upper-mid on sturdy rock with space for branching and to avoid shading neighbors. Keep 3–6 inches from other SPS and farther from aggressive LPS or soft corals; run carbon and good skimming if mixing species. Dip and inspect on arrival (check for AEFW, red bugs), then light-acclimate by starting lower or reducing output 30–50%. Common issues: bleaching from sudden light/parameter shifts, tissue recession from pests or alk swings, and browning from low light or imbalanced nutrients. Improve flow, verify PAR, correct parameters slowly, and frag ahead of dead tissue if recession starts.

FAQ

Frequently Asked Questions

About the GB Fury Acropora Coral

  • Why does my GB Fury Acropora (A. tenuis) lose neon tips under strong light while other acros don’t?
    A. tenuis often shows its best tip fluorescence under high PAR with heavy 420–450 nm and a touch of 400–415 nm. If alk runs high (9.5+ dKH) under intense light, tips can “burn” and pale. Keep alk 7.8–8.5, maintain moderate nutrients (NO3 5–15 ppm, PO4 0.03–0.08), and avoid rapid light increases. Gradual spectrum ramping preserves tip color.
  • My colony encrusts fast but stalls on vertical branches—normal for this species?
    Yes. Tenuis prefers to encrust a wide base before throwing robust axial branches. Encourage upward growth by providing high, variable flow across the base to prevent detritus film, keeping PAR 250–350 at the base, and slightly lowering nutrients once a healthy plate forms. Mount the frag on a low-profile plug or flat tile so the rim isn’t shaded.
  • What subtle pests or stress signs show up uniquely on GB Fury tenuis?
    Early AEFW activity shows as tiny, crescent bite marks and reduced polyp extension on shaded undersides. Red bugs cause dulling and chronic minimal extension. Tip burn from alk/light stress looks like clean, white tips without rough bite edges. Address bites with targeted dips and quarantine; for burn, stabilize alk and back down PAR 10–15% for a week.
  • How can I keep lower branches from dying off due to self-shading?
    Place the colony where crossflow sweeps around it, not just at the tips. Angle the frag slightly so light reaches interior radial corallites. Trim a few inner branches quarterly to open the canopy. Maintain moderate nutrients and consider a small UV/violet bump at photoperiod peak to penetrate deeper structure without raising total PAR too much.
