Why do my Candy Cane Coral heads swell and shrink through the day, and when should I feed?

Caulastrea furcata polyps often deflate under higher light and re-inflate toward evening. Their feeding tentacles extend most after lights out. Target-feed small meaty foods (e.g., mysis, finely chopped shrimp) 30–60 minutes after dusk when feeders are visible. If they stay retracted at night, reduce flow slightly and try a drop of amino or food scent to cue extension.

My green Candy Cane turned pale mint under brighter LEDs. Is this light shock or nutrients?

Often both spectrum and nutrient balance drive color. This species comes from turbid, nutrient-bearing lagoons and prefers moderate PAR. Intense blue-heavy light can wash greens if nitrates/phosphates are near-zero. Aim for moderate PAR, stable alkalinity, and modest nutrients (e.g., NO3 5–15 ppm, PO4 0.03–0.1). Gradually re-acclimate to light; avoid large white-channel jumps.

How can I spot and stop early tissue recession on a single head?

Look for a thin, receding ring exposing new white skeleton around the septa—often tied to alkalinity swings or physical abrasion. Stabilize alk/cal/mag, soften flow so tissue isn’t whipping on skeleton, and feed lightly at night. If brown, stringy decay forms (brown jelly), frag off the affected branch below healthy tissue and use a brief iodine dip; improve aeration and flow.

Do Candy Canes have long sweepers, and how close can I place them to other LPS?

Their sweepers are modest (typically under 2 inches) but can still sting neighbors overnight. Give a couple inches of space from Acanthastrea, Favites, or soft corals that may encroach. Avoid placing beneath aggressive Euphyllia directionally “downwind.” Watch for vermetid snails or bristleworms irritating tissue at the base; relocating or removing the irritant often stops localized recession.

Beginner Corals LPS

Overview

Candy Cane Coral has fleshy, puffed polyps with contrasting banded heads on branching skeletons. Caulastrea furcata is a stony, branching LPS coral that prefers moderate light and low to moderate water flow. It is photosynthetic via symbiotic algae but benefits from occasional small meaty foods, which can boost growth and deepen coloration. Place with space around it; nighttime sweeper tentacles can sting nearby corals.

Care & Placement

Candy Cane Coral (Caulastrea furcata) thrives with stable, moderate conditions. Provide moderate lighting (PAR ~70–150); start low in the tank and move up slowly over 2–3 weeks to avoid bleaching. Aim for moderate, indirect flow that keeps detritus off the fleshy heads without making them whip. Feed 2–3 times weekly with small meaty foods (mysis, enriched brine, LPS pellets) or fine particulate foods; target feed in the evening when feeding tentacles extend. Keep temperature 24–26°C/75–78°F, salinity 1.025–1.026, pH 8.0–8.4, alkalinity 8–9.5 dKH, calcium 400–450 ppm, magnesium 1250–1350 ppm, nitrate 2–10 ppm, phosphate 0.03–0.08 ppm. Test weekly and correct slowly; this coral is sensitive to sudden swings, especially in alkalinity and light.Place low to mid-height on stable rock or rubble; avoid burying heads in sand. Leave 7–10 cm (3–4 in) from neighbors, as short sweeper tentacles appear at night. Generally peaceful, but do not crowd with other fleshy LPS. Acclimate with a 30–60 minute drip and light acclimation (reduced intensity or mesh screen). Common issues: tissue recession from too much flow or alk instability; pale tissue from excess light or ultra-low nutrients; brown jelly can follow injury—frag away affected heads and improve flow. Secure frags so snails or fish can’t knock them over. Quarantine and dip new pieces to prevent pests. Regular feeding and stable parameters promote steady growth and strong coloration.
