Kenya Tree Coral

Capnella spp.

The bulletproof beginner tree coral — so hardy it can spread; a great first coral, kept in check.

Difficulty: BeginnerSoft coral (beginner)

The Kenya tree coral (Capnella spp.) is the coral you almost can't kill — a soft, bushy "tree" that pulses gently and shrugs off conditions that would sulk other corals. That hardiness is also its catch: it grows fast and drops little branches that root and grow into new trees, so in a happy tank it can spread like a weed. A brilliant, cheap first coral — kept in check.

Good to know: Drops branches that grow into new colonies — can become weedy; give it its own rock.

📊 What keepers actually ask: Recommended as a bulletproof first coral; the recurring lesson is "it's taking over" — it self-propagates by dropping branches.

Care at a glance

Colony / form	A soft, branching tree of polyps; droops by day, puffs up to feed.
Lighting	Low to moderate (≈80–250 PAR) — very adaptable.
Water flow	Moderate — it sways and sheds waste in decent flow; bottom-to-mid placement.
Placement	Lower or mid rock, ideally on its own island of rock — it spreads by dropped branches, so keep it off shared rock.
Temperature	75–82°F (24–28°C).
pH	8.1–8.4.
Specific gravity	1.023–1.026 (reef-standard ≈35 ppt).
Other targets	Soft corals don't draw down calcium and alkalinity like stony corals — just keep salinity and the usual reef parameters stable.
Feeding	Photosynthetic; benefits from the general food in the water — no target-feeding needed.
Growth & spread	Fast — and it propagates itself by dropping branchlets that settle and grow (can become invasive).
Natural range	Indo-Pacific.

Beginner-friendly, done right. About the hardiest coral in the hobby and a superb confidence-builder — it tolerates low light, imperfect water and a wide range of flow. The only real "problem" is success: Kenya tree grows fast and drops branches that root wherever they land, so it can spread across your rock and crowd other corals. Give it its own rock island, prune stray branchlets, and enjoy an almost unkillable first coral. Keep salinity stable.

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.

"It's drooping, so it's unhealthy." Kenya trees naturally droop and look deflated at times (especially by day), then puff up — it's normal, not a sign of trouble.
"Soft corals grow slowly." Kenya tree can spread fast and become weedy by dropping branchlets — great for a new tank, but keep it contained.

Before you buy

Its own rock island (it spreads by dropped branches).
A willingness to prune it back so it doesn't crowd other corals.
Any decent light and moderate flow — it's very forgiving.

Signs something's wrong

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

Staying shrivelled and not puffing up for days — check water (it takes a lot to bother a Kenya tree).
Tissue rot or melting at the base — a real problem; cut to healthy tissue, re-attach, and check water.
Spreading over other corals — prune the branchlets; it's competing for space.

Never

Never assume drooping means dying — it's normal for this coral.
Never plant it on shared rock if you want a tidy reef — it spreads.
Never let dropped branches root among prized corals unchecked.

Common kenya tree coral questions

Is the Kenya tree coral good for beginners?

It's one of the best — arguably the hardiest coral in the hobby, tolerant of low light, moderate flow and imperfect water. It's a brilliant confidence-builder; the only catch is that it grows fast and can spread.

Why does my Kenya tree look droopy and deflated?

That's normal — Kenya trees naturally droop and shrink at times (often during the day) and puff back up later. It's not a sign of illness unless it stays shrivelled for days alongside other warning signs.

Does Kenya tree coral spread or become invasive?

It can — it grows quickly and propagates by dropping small branchlets that settle and grow into new colonies. Give it its own rock island and prune strays so it doesn't crowd other corals.

How much light does a Kenya tree need?

Not much — low to moderate light (roughly 80–250 PAR) suits it, and it adapts to a wide range. It's genuinely forgiving.

Do I need to feed Kenya tree coral?

No target-feeding required — it's photosynthetic and takes what it needs from light and the food already in the water.
