The honest cost

How much does it cost to keep a Stylophora?

The honest answer: the stylophora itself is usually the cheapest part — the reef SYSTEM is the real cost. You don't buy a setup per animal; keeping any marine species means running a reef system, and that system is where the money goes. We don't quote prices (they vary by country, currency and month) — we show you what you're paying for and where the money actually goes.

Where a stylophora sits on the cost spectrum: A stylophora pushes you toward the higher-cost end of the reef spectrum: it wants strong lighting, strong flow, dosing and tight, stable parameters — so the system behind it has to be more capable, not less.

💷 Upfront — the reef system (the real cost)

Keeping a stylophora means running a reef. This is that system — the real cost of entry, not the animal.

Display tank + live rock: The tank and its live rock — the home and the biological filter. This, not the stylophora, is the real cost of entry. Bigger, more stable water is more forgiving; buying too small twice costs more than buying right once.
Marine lighting: Proper reef lighting (Moderate to high — around 300–400 PAR once acclimated.). A stylophora is photosynthetic — its light is not optional décor, it's how the animal feeds itself, and it's one of the heaviest single lines for a light-hungry coral like this.
Flow (powerheads): Water movement from powerheads (Moderately strong, alternating or random — enough to keep the branches clean.). A stylophora needs strong, well-distributed flow — a real, sometimes multi-pump cost, so this is a genuine line, not an extra.
Heater: A heater to hold a stable tropical temperature (75–82°F (24–28°C).). Cheap relative to everything else, but not optional.
Protein skimmer: A skimmer for most reef systems — it exports waste before it becomes nitrate. Sizeable, and one of the pieces people wrongly try to skip.
Salt mix + RO/DI: Marine salt mix, plus either an RO/DI unit (a real upfront cost that pays back over time) or buying RO/DI water. Never mix salt into tap water — this is where corners cost you the tank.
Test kits: Salinity (a refractometer) plus the core reef tests — for a coral, that means alkalinity, calcium and magnesium too. You genuinely cannot run a reef by guesswork.
Dosing gear: Because a stylophora builds a skeleton (or, for an anemone, needs rock-stable water), you'll be replacing alkalinity, calcium and magnesium as it grows — by hand at first, then often with a doser. For a demanding species like this, stable dosing is closer to a requirement than an upgrade.
The animal itself: Usually the SMALLEST line on this whole list. The price of the stylophora tells you almost nothing about the cost of keeping it well — the system does.

🔁 Ongoing — the part people forget

The costs that keep coming for as long as the tank runs.

Salt + RO/DI water: Every water change needs fresh saltwater — salt mix plus RO/DI water. Constant, for the life of the tank, and it scales with tank size.
Electricity: The biggest hidden cost of a reef: the lights, return pump, powerheads, heater, skimmer all run 24/7. Over a year the power bill can quietly rival everything else — and it scales with a bigger tank.
Test kits + dosing supplements: Reef test reagents get used up, and a stylophora steadily consumes alkalinity, calcium and magnesium as it grows — you replace them with dosing supplements. Small per week, constant for the tank's life.
Food: Mostly light-fed, but mostly photosynthetic; benefits from the general food in a stocked reef. — a small, occasional cost.
"Vet" = testing + correcting: Be honest: there is no vet for a stylophora. A struggling coral is almost always a water-chemistry or husbandry problem — so the real "vet cost" here is testing and correcting: reagents, RO/DI, salt and dosing supplements. Our free parameter, water-test and dosing tools do the diagnosing for free.

✅ Worth the money

Stable alk/Ca/Mg, tested weekly, BEFORE any SPS.
Moderate-to-high light (acclimate a new frag) and moderately strong flow.
A matured tank — SPS want consistency.

These are this species' own "before you buy" essentials from our sourced care sheet.

🟡 Save your money

All-in-one "nano" starter kits — the small ones are usually too limiting, so you outgrow and re-buy. Buy the tank you'll want in a year.
A cheap swing-arm / floating hydrometer — get a refractometer instead (a criterion, not a brand): salinity is too important to read off an inaccurate toy.
Gimmick "reef boosters" and additives beyond what your own test kit says the tank actually needs — dose to a measured number, never to a marketing promise.
"Miracle" coral-colour supplements — stable, well-tested water grows better colour than any bottle.

⛔ Never buy

Never add SPS before your alk/Ca/Mg are stable and tested weekly.
Never jump a new frag into full light — acclimate.
Never let alkalinity swing.

These are on this species' "never" list in our care sheet — cheap, common, and harmful.

The one rule on cost: budget where it's safe — a second-hand tank and rock — but never cheap out on the salt or RO/DI water quality, the test kits, or stable parameters. Those are where cutting corners costs the stylophora its health, and usually costs you more later. We don't quote prices — check current prices where you live; this is what to budget for.

Cost questions

How much does it cost to keep a stylophora?

More than it costs to buy the stylophora — the animal is usually the cheapest part. The real cost is the reef SYSTEM: the display tank and live rock, marine lighting, flow, a heater, a skimmer, salt mix and RO/DI water, test kits and dosing gear. We don't quote a figure because prices vary a lot by country, currency and month — this page shows exactly what you're paying for, so you can price it up locally.

What are the ongoing costs of keeping a stylophora?

Salt and RO/DI water for water changes, electricity (lights, pumps, powerheads, heater and skimmer run 24/7 — the biggest hidden cost of a reef, and it scales with tank size), test kits and dosing supplements, food, and — honestly — there's no vet for a stylophora: a struggling coral is a water-chemistry fix, so the "cost" is testing and correcting.

Why does the setup cost more than the stylophora itself?

Because you're not buying an animal — you're running an ocean in a box. A stylophora needs stable saltwater, the right light, proper flow, steady temperature and clean water, and that equipment is where the money goes. The purchase price of the stylophora tells you almost nothing about the cost of keeping it properly.

Where can I save money keeping a stylophora — and where shouldn't I?

Safe to save: buy the tank and rock second-hand, and skip all-in-one kits and gimmick additives. Never cut corners on the salt or RO/DI water quality, the test kits, or stable parameters (alk/Ca/Mg) — those are where saving money costs the stylophora its health, and usually costs you more later.
