Pocillopora

Pocillopora damicornis

The forgiving, fast-growing SPS — the classic bridge from LPS to a full SPS reef.

Difficulty: Beginner–IntermediateSPS coral (advanced)

Pocillopora (Pocillopora damicornis), the cauliflower or "pocci" coral, is the SPS that changed a lot of minds — fast-growing, wildly adaptable and forgiving, it's widely considered the best bridge from LPS into a full SPS reef. Bumpy, verrucae-covered branches in pink, green and brown fill in fast once your parameters are stable. Just check new frags for the same pests that plague Acropora.

Good to know: Moderate-high light + strong turbulent flow; hardy and fast, but can carry SPS pests (dip and inspect).

📊 What keepers actually ask: The recurring "how do I get into SPS?" answer, with stylophora; the recurring caveat is dipping new frags for pests.

Care at a glance

Colony / form	Bushy branches covered in wart-like bumps (verrucae); grows fast and dense.
Lighting	Moderate to high — around 150–300 PAR.
Water flow	Strong and turbulent — it loves flow that keeps the branches clean.
Placement	Mid-to-upper rock in good light and strong flow, once acclimated.
Temperature	75–82°F (24–28°C).
pH	8.1–8.4.
Specific gravity	1.023–1.026 (reef-standard ≈35 ppt).
Other targets	SPS build a dense stony skeleton and punish parameter swings far harder than LPS — keep alkalinity (≈8–11 dKH), calcium (≈400–450 ppm) and magnesium (≈1300–1400 ppm) rock-stable and test weekly.
Feeding	Mostly photosynthetic; benefits from the general food in the water.
Growth & spread	Very fast for an SPS — one of the quickest-growing corals; often reproduces in-tank.
Natural range	Indo-Pacific.

Beginner-friendly, done right. Along with stylophora, the go-to "first SPS" — fast, adaptable and forgiving, and a natural stepping stone from LPS to Acropora. Give it moderate-to-high light and strong turbulent flow, acclimate new frags to the light, and keep alk/Ca/Mg rock-stable. Two notes: it grows FAST (give it room), and it can carry the same pests as Acropora (Acropora-eating flatworms, red bugs) — so dip and inspect new frags. A brilliant, rewarding SPS to build confidence on.

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.

"SPS are all slow and finicky." Pocillopora is one of the fastest-growing, most forgiving corals in the hobby — a great first SPS.
"Only Acropora gets pests." Pocillopora can carry SPS pests too (flatworms, red bugs) — dip and inspect new frags like you would an acro.

Before you buy

Stable alk/Ca/Mg, tested weekly, before any SPS.
Moderate-to-high light and strong turbulent flow; room for fast growth.
A pest-dip routine for new frags (it can carry acro pests).

Signs something's wrong

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

Rapid tissue loss or white skeleton (RTN/STN) — a parameter swing; frag ahead and fix stability.
Pale or brown — light not acclimated, or nutrients off.
Tiny bite marks or pests on branches — dip and inspect (flatworms/red bugs).

Never

Never add SPS before your parameters are stable and tested weekly.
Never add a new frag un-dipped (it can carry pests).
Never let alkalinity swing.

Common pocillopora questions

Is pocillopora a good first SPS?

Yes — it's one of the fastest-growing and most forgiving SPS, and along with stylophora it's the classic bridge from LPS into a full SPS reef. Give it stable parameters, good light and strong flow and it fills in quickly.

How much light and flow does pocillopora need?

Moderate to high light (around 150–300 PAR) and strong, turbulent flow to keep the bumpy branches clean. Acclimate new frags to the light over a couple of weeks.

How fast does pocillopora grow?

Very fast for an SPS — it's one of the quickest-growing corals and often reproduces in the tank. Give it room, because it fills in and can shade slower neighbours.

Does pocillopora get pests like Acropora?

It can — pocillopora can carry SPS pests such as Acropora-eating flatworms and red bugs, so dip and inspect new frags before adding them, the same as you would an acro.

Stylophora or pocillopora for a first SPS?

Both are excellent, hardy first SPS. Pocillopora grows faster and is a touch more adaptable; stylophora has stouter branches. Either is a great stepping stone from LPS toward Acropora.
