Candy Cane Coral

Caulastrea furcata

The candy-striped starter LPS — hardy, peaceful, and it buds into more heads the more you feed it.

Difficulty: BeginnerLPS coral

The candy cane coral (Caulastrea furcata) — also called trumpet or bullseye coral — is one of the best first LPS: hardy, peaceful, and made of glowing striped heads on branching stalks that bud into more heads the more you feed it. Low-to-moderate light, gentle flow, a spot on the lower rock or sand, and a couple of feeds a week turn one frag into a showpiece colony.

Good to know: Low-moderate light + gentle flow; spot-feed to grow new heads.

📊 What keepers actually ask: Recommended constantly as a first LPS; the recurring "how do I get more heads?" answer is: feed it.

Care at a glance

Colony / form	Branching stalks, each topped by a round striped head; multiplies by budding new heads.
Lighting	Low to moderate — around 50–70 PAR (30–150 acceptable). Not a bright-light coral.
Water flow	Low to moderate, indirect — enough to keep detritus off, not enough to stop the heads inflating.
Placement	Lower rock or the sand bed; give the heads room to inflate and to add new ones.
Temperature	75–82°F (24–28°C).
pH	8.1–8.4.
Specific gravity	1.023–1.026 (reef-standard ≈35 ppt).
Other targets	LPS build a stony skeleton — keep alkalinity (≈8–11 dKH), calcium (≈400–450 ppm) and magnesium (≈1300–1450 ppm) stable.
Feeding	Photosynthetic PLUS meaty spot-feeding (mysis, small pieces) 2–3× a week — it feeds at night, and feeding drives new heads.
Growth & spread	Steady — buds new heads and fills out into a dense colony; easy to frag.
Natural range	Indo-Pacific.

Beginner-friendly, done right. A superb beginner LPS — hardy, peaceful (no aggressive sweepers to speak of) and very rewarding. Keep the light low-to-moderate (it's not a high-light coral), the flow gentle (strong flow stops the heads inflating), and place it low. The magic is feeding: candy cane responds to a couple of meaty spot-feeds a week by budding new heads, so a small frag becomes a full colony. Keep alk/Ca/Mg stable like any LPS.

Keep those numbers steady. This coral's alkalinity, calcium and magnesium only keep it safe when they're stable. If one reads low, our free reef dosing calculator works out exactly how much to add for your water volume — and splits it safely over days.

Where does it go? Light, flow and placement make or break a coral. Our free coral placement guide shows the PAR, flow and tank zone this coral wants — and what else thrives in the same spot.

The fish store gets these wrong

Common myths, kindly corrected — no shame for having believed them.

"LPS all need bright light." Candy cane is a low-to-moderate-light coral — too much light can bleach it. Keep it lower and shadier.
"You don't need to feed photosynthetic corals." Candy cane grows far faster and buds more heads when spot-fed — feeding is how you turn a frag into a colony.

Before you buy

A low-to-moderate-light, gentle-flow spot on lower rock or sand.
Stable alk/Ca/Mg (it's a stony coral).
Meaty foods to spot-feed a couple of times a week.

Signs something's wrong

A struggling coral is almost always telling you about light, flow or water — here's what to watch for:

Heads not inflating — usually too much flow, or a parameter issue.
Receding tissue or exposed skeleton between heads — a chemistry swing or a brown-jelly-type infection; check water.
Pale or bleaching — too much light.

Never

Never keep it under intense light or strong flow — the heads won't inflate.
Never let alkalinity swing (it's a stony coral).
Never skip feeding if you want it to multiply.

Common candy cane coral questions

Is candy cane coral good for beginners?

Yes — it's one of the best first LPS corals: hardy, peaceful, undemanding on light and flow, and very responsive to feeding. Give it low-to-moderate light, gentle flow and stable parameters.

How do I get my candy cane to grow more heads?

Feed it. Candy cane is photosynthetic but buds new heads much faster when spot-fed meaty foods (mysis, small pieces) two or three times a week — that's how a small frag becomes a full colony.

How much light and flow does candy cane need?

Low to moderate light (around 50–70 PAR) and gentle, indirect flow. Too much of either stops the heads inflating, and strong light can bleach it.

Where should I place candy cane coral?

Low in the tank — on lower rock or the sand bed — in a calm, lower-light, gentle-flow spot, with room for the heads to inflate and for new ones to bud.

Is candy cane coral aggressive to other corals?

It's one of the more peaceful LPS — it doesn't have the long stinging sweeper tentacles of Euphyllia — so it's an easy neighbour, though it's still wise to leave a little space as it spreads.
