How does Mango Haze Echinata differ from “Acan lords,” and how should I place it?

Acanthastrea echinata grows as a rigid encrust with sharp ridges and is far more aggressive than Micromussa lordhowensis. It can extend mesenterial filaments and burn neighbors on contact. Mount it on its own rock island with a buffer zone, moderate indirect flow, and low–moderate light. Prioritize stability over rapid growth; sudden PAR spikes often cause edge recession.

My Mango Haze is fading from orange/yellow to dull tan under heavy blues—what’s the likely cause?

Ultra-low nutrients and high blue-only lighting often wash out carotenoids. Aim for NO3 around 5–15 ppm and PO4 0.05–0.10 ppm. Introduce a whiter midday period (10–14K) for 2–4 hours and feed small meaty foods at night 1–2x weekly. Reduce PAR gradually to 80–150 at the coral to recover saturation.

Why does tissue recede from the edges after a routine cleaning or light change?

Echinata responds poorly to abrupt shifts in flow patterns, detritus exposure, or PAR jumps. Edge recession often follows micro-abrasion and bacterial irritation. Blow off debris gently, increase laminar flow slightly to keep the rim clean, reduce PAR by 20–30% immediately, and apply an iodine dip. If recession continues, cut into healthy tissue to save unaffected sections.

Can Mango Haze coexist with SPS on the same rockwork?

It’s risky. Even without long sweepers, it can deploy filaments at night and damage SPS that touch or are downcurrent. Place SPS at least 10–15 cm away and upstream of flow. Use epoxy barriers or separate islands. If contact occurs, trim the echinata edge or move the SPS promptly—burned areas on sticks often lead to base STN.

Mango Haze Echinata Coral

Overview

Mango Haze Echinata Coral shows thick, ridged lobes with a low, encrusting profile and distinct, raised mouths. Acanthastrea echinata Coral is a large‑polyp stony coral that prefers low to moderate light and moderate, indirect water flow. It relies on symbiotic algae for energy but also benefits from small meaty feedings, which support growth and coloration. Place on rockwork with space from other corals, as it can extend stinging tentacles at night.

Care & Placement

Mango Haze Echinata Coral (Acanthastrea echinata Coral) prefers stable, nutrient-balanced systems with low to moderate light and moderate, indirect flow. Aim for PAR 80–150; start low and increase slowly to avoid bleaching. Provide a varied diet 2–3 times weekly after lights down: small meaty foods (mysis, chopped shrimp), reef pellets, and amino-rich foods to improve color and growth. Target feed gently to avoid retraction. Maintain temperature 75–78°F (24–26°C), salinity 1.025–1.026, pH 8.1–8.4, alkalinity 8.0–9.5 dKH, calcium 400–450 ppm, magnesium 1250–1350 ppm, nitrate 2–10 ppm, and phosphate 0.03–0.08 ppm. Test weekly with reliable kits and use a refractometer; stability matters more than chasing exact numbers.Place this coral low to mid in the rockwork with indirect flow that keeps detritus off without blasting tissue. Leave 3–6 inches from neighbors; it can sting at night and may be harmed by very aggressive LPS. Acclimate by dripping 30–45 minutes, dip for pests, and light-acclimate with shaded placement or screen for 1–2 weeks. Signs of trouble: paling/bleaching (too much light), tissue recession (alk swings, low nutrients, harsh flow), or brown jelly (isolate, trim, and improve flow). If recession starts, verify alkalinity and salinity, reduce light, increase gentle flow, and resume small, frequent feedings. Keep parameters steady during growth spurts to prevent skeleton exposure at the edges.
