Why did my Little Red Ferrari Acropora fade from deep red to pink or brown?

Color shifts usually track light spectrum, nutrients, and key traces. Aim for PAR 250–400 with strong blue/violet (400–460 nm) and minimal warm white. Keep NO3 at 5–15 ppm, PO4 at 0.03–0.08 ppm, alkalinity 7.5–8.5 dKH, potassium 380–420 mg/L, and iodine 0.03–0.06 ppm. Avoid rapid changes; ramp lighting over 2–3 weeks after introduction or moves.

How should I place it to prevent base shading and slow tissue loss?

A. tenuis encrusts before branching, then self-shadows. Mount slightly angled with 6–8 inches clearance, and provide cross-current, turbulent flow from multiple directions. Periodically prune inner or downward branches to open light paths. Consider side or back lighting to reach the base. Stable nutrients and alkalinity reduce basal STN risk when the colony becomes dense.

My polyp extension stalled after great initial growth—what could be wrong?

Check for early pests (tiny bite marks, sand-like eggs) indicating AEFW or red bugs. Use a dip and magnification to confirm. If clean, review flow (increase random turbulence), nighttime feeding (amino acids or fine zooplankton 1–2x weekly), and micro-imbalances—especially potassium and iodine. Also rule out abrupt alkalinity or temperature shifts; even brief swings can suppress PE for days.

How do I respond to sudden tissue loss on this coral?

First, stabilize parameters and increase aeration and flow. Start fresh carbon, halt major adjustments, and perform an iodine or antiseptic dip. Frag healthy tips above the recession line and remount. Inspect for pests and remove any detritus trapped within branches. Maintain moderate light for a few days, then return to target PAR once recession stops and polyps resume.

Little Red Ferrari Acropora Coral

Acropora

Overview

Little Red Ferrari Acropora Coral shows bright red branch tips with tight radial corallites on a branching skeleton. Acropora tenuis is a small-polyp stony coral that prefers strong light and high, turbulent flow. It relies mainly on symbiotic algae for energy, and occasional small-particle foods can support growth and color. Place high on stable rockwork with room for upward growth, and keep clear of aggressive neighbors.

Care & Placement

Little Red Ferrari Acropora Coral (Acropora tenuis) thrives under strong, stable conditions. Provide high light at 250–350 PAR with a blue-heavy spectrum; ramp intensity over 1–2 weeks using a screen or dimming to avoid bleaching. Aim for strong, random flow that keeps polyps moving and keeps detritus off branches; alternate flow patterns help prevent dead spots and tissue recession. Keep temperature 75–78°F (24–26°C), salinity 1.025–1.026, pH 8.1–8.4, alkalinity 7.5–9 dKH (stable), calcium 420–460 ppm, magnesium 1300–1400 ppm, nitrate 2–10 ppm, and phosphate 0.02–0.08 ppm. Test at least weekly (alk daily when dialing in) and dose to hold numbers steady. Feed small-particle foods (reef roids, rotifers) 1–2x weekly and consider light amino acids; don’t overfeed—clarity and stable nutrients help color and growth.Place frags high on sturdy rock with room for upward and outward growth; allow 3–4 inches from other corals to limit shading and sting risk. Avoid neighbors with long sweepers (e.g., Galaxea, some Euphyllia). Acropora are sensitive to swings and pests; drip acclimate, dip new pieces, and inspect for flatworms or red bugs. If you see paling or sudden tissue loss, check alkalinity and temperature first, reduce light temporarily, improve flow, and perform a controlled water change. Brown tips or burnt tips often signal alk/nutrient imbalance. Maintain strong export (skimming, refugium) and clean powerheads to keep flow consistent. Regularly trim encroaching colonies to prevent overgrowth and shadowing.
