Why does my Cloverfield Pectinia inflate by day, deflate at dusk, and throw very long sweepers at night?

Pectinia sp. follows a daily expansion cycle: tissue puffs under light for photosynthesis and relaxes at night to feed. After lights out, it can deploy sweepers 6–10 inches. Give wide clearance from other corals, keep flow gentle so sweepers don’t whip and tear, and offer fine particulate foods at night when feeding tentacles are out.

What placement best preserves color without causing valley recession?

Aim for lower–moderate light with strong blue spectrum, similar to turbid, deeper reef zones. Start shaded and acclimate slowly to avoid bleaching. Use low–moderate, indirect flow to prevent tissue flapping. Mount slightly tilted or vertical so detritus doesn’t collect in valleys. Siphon debris weekly; trapped waste often drives cyanobacteria and slow tissue loss between ridges.

I’m seeing tissue peel from ridge tips and along the base—what’s the likely cause and fix?

Sudden alkalinity shifts, excess light, and vermetid snail cuts commonly start recession. Stabilize alk (8–9 dKH) and nutrients, reduce light 20–30% temporarily, and cap vermetid tubes with glue or epoxy. If slime or foul odor appears, do an iodine dip and trim dead skeleton to stop spread. Improve laminar flow around the base to deter detritus buildup.

What feeding routine boosts growth without fueling nuisance algae?

Feed small particle foods (reef blends, rotifers, fine mysis) 1–2 times weekly after lights out. Target gently; avoid big meaty chunks. Support coloration with non-zero nutrients: nitrate 5–15 ppm, phosphate 0.03–0.1 ppm. Consider amino acids sparingly. Maintain trace balance via regular water changes; abrupt spikes from heavy feeding often dull colors and trigger film algae.

TSA Cloverfield Pectinia Coral

Pectinia LPS

Overview

Cloverfield Pectinia Coral features ruffled, fluted plates with scalloped ridges and fleshy polyps. Pectinia sp., a large-polyp stony coral with plating growth, prefers moderate lighting and gentle to moderate water flow. It is photosynthetic with symbiotic algae but benefits from occasional small meaty feedings, which can support faster growth and stronger color. Give it space from neighbors due to long nighttime sweeper tentacles, and place it where its plates are protected from strong currents.

Care & Placement

Cloverfield Pectinia Coral (Pectinia sp.) thrives with stable, moderate conditions and careful spacing. Provide moderate lighting (PAR ~80–150); too much light can bleach, too little can dull color. Start low and increase light over 2–3 weeks using shading or shorter photoperiods. Aim for moderate, random water flow to keep detritus off the ridges without blasting tissue; alternate patterns help prevent dead spots. Feed 1–3 times weekly with fine meaty foods or zooplankton, ideally at dusk when feeding tentacles extend; target feed gently to avoid stress. Maintain temperature 24–26°C (75–79°F), salinity 1.025–1.026, pH 8.1–8.4, alkalinity 8.0–9.5 dKH, calcium 400–450 ppm, magnesium 1300–1400 ppm, nitrate 2–10 ppm, phosphate 0.03–0.08 ppm. Monitor with reliable test kits, a refractometer, and—if possible—a PAR meter; this coral is sensitive to rapid swings, especially in alkalinity and light.Place frags or colonies low to mid in the tank on stable rock with room to grow. Allow 6–10 inches clearance from neighbors; Pectinia extends long nocturnal sweepers and can sting nearby corals. Avoid abrasive sand contact. Acclimate with a gentle dip and slow temperature/salinity matching. Common issues include bleaching (reduce light, verify nutrients), tissue recession (improve flow, stabilize alkalinity, siphon detritus), and brown jelly (frag away infected areas, increase aeration). Use a turkey baster to keep surfaces clean, and handle carefully—flesh tears easily. Compatibility is best with peaceful, non-encroaching neighbors and well-managed nutrients.
