30+ gal mature reef / moderate light + flow

Mature reef with moderate light + flow. Will spread asexually if conditions are good.

Photo coming soon
Ideal

Mature mixed reef

75+ gal mature mixed reef

Mature 75+ gal mixed reef where small anemones can colonise rockwork. Mini Maxi (Stichodactyla tapetum) is a tiny carpet — beginner-friendlier than full-size carpets; doesn't host clownfish.

Life & growth stages

How this animal changes through its life — each stage often has its own care, diet and space needs.

Photo coming soon
Planula larva

Corals begin as a free-swimming planula larva released into the water column after spawning or brooding. The tiny, ciliated larva drifts and swims until it finds suitable hard substrate to settle on.

Photo coming soon
Single polyp

Once settled, the larva metamorphoses into a single founding polyp that secretes a calcium-carbonate (or proteinaceous) base and extends a ring of tentacles to feed. Reef-building corals begin laying down skeleton at this stage.

Mature colony stage
Mature colony

The founding polyp buds asexually into a colony of many genetically identical polyps, building the species' characteristic growth form — branching, plating, encrusting, or massive. A mature colony can reproduce and contributes to reef structure.

Color & pattern variants

Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.

Natural
Rainbowrepresentative

Rainbow

Multicolor morph blending red, green, blue, and orange across the disc and tentacles — the most prized and recognizable mini-maxi color form.

Purple / Magentarepresentative

Purple / Magenta

Solid vivid purple-to-magenta disc with contrasting tentacle tips; a popular single-color variant.

Green / Tippedrepresentative

Green / Tipped

Green disc with brightly colored tentacle tips, fluorescing strongly under actinic lighting.

Ultra Grade Rainbow Maxi-Minirepresentative

Ultra Grade Rainbow Maxi-Mini

RareBeginner

The top color grade of *Stichodactyla tapetum*, blending green, blue, purple, pink and orange across the oral disc into a true multicolor 'rainbow' that fluoresces hard under actinic light. Roughly 1.5-3 inches; viewed best top-down.

Tip: Place on or near the sandbed in low-to-moderate flow and let it tuck its foot into rock/sand to anchor; once attached it rarely wanders. Moderate light (~100-200 PAR) is plenty; heavy actinic brings out the rainbow fluorescence. Wear gloves when handling — the sting can irritate skin.

Rainbow Maxi-Mini Carpetrepresentative

Rainbow Maxi-Mini Carpet

UncommonBeginner

The standard 'rainbow' trade designation — a mottled mix of green, teal, purple and orange across the disc, less saturated than the Ultra grade but still multicolor. Intensely fluorescent top-down under blue light.

Tip: Give it low-to-moderate flow and let it settle on the sandbed near rockwork; avoid blasting it directly until the foot grips. It has a potent sting, so keep it away from other corals and wear gloves when handling.

Rainbow Rim Maxi-Minirepresentative

Rainbow Rim Maxi-Mini

UncommonBeginner

A maxi-mini with a contrasting brightly colored outer ring ('rim') of rainbow tones encircling a differently colored center disc. The rim coloration shifts noticeably between white and actinic lighting.

Tip: Position under moderate blue-heavy light to pop the rim fluorescence, on sand in gentle-to-moderate flow until it anchors its foot. Keep it isolated — its sting can damage neighboring corals; gloves recommended.

Grade B Maxi-Mini Carpetrepresentative

Grade B Maxi-Mini Carpet

CommonBeginner

An entry-level color grade — typically green/brown with some purple or blue accents, lacking the full multicolor spread of Grade A or Ultra pieces. Hardy and inexpensive.

Tip: Treat it like any maxi-mini: sandbed placement, low-to-moderate flow, moderate light. A great beginner anemone since it tolerates a wide range of conditions and clones readily. Mind the sting and wear gloves.

Orange Maxi-Mini Carpetrepresentative

Orange Maxi-Mini Carpet

UncommonBeginner

A maxi-mini dominated by orange tentacles/disc, frequently with a contrasting purple or maroon center. The orange is a striking solid color rather than a multicolor mix.

Tip: Keep it on sand in low-to-moderate flow under moderate light; the orange holds best without being washed out by overly intense white lighting. Mind the strong sting near other livestock.

Royal Blue Maxi-Mini Carpetrepresentative

Royal Blue Maxi-Mini Carpet

UncommonBeginner

A royal-blue to purplish-blue maxi-mini — one of the more sought-after solid colors, with the blue intensifying dramatically under actinic light. Disc and short tentacles share the blue tone.

Tip: Use blue-spectrum light to maximize the color and keep flow low-to-moderate; let it anchor on the sandbed near rock. As with all maxi-minis, isolate it from corals due to its sting and wear gloves.

Purple Maxi-Mini Carpetrepresentative

Purple Maxi-Mini Carpet

UncommonBeginner

A maxi-mini with a predominantly purple to magenta disc, sometimes with occasional green highlights. A clean single-color look prized for contrast against green-dominant tanks.

Tip: Moderate light and low-to-moderate flow on the sandbed; purple tones tend to read best under a mix of white and blue. Keep clear of corals — the sting is potent for the animal's small size.

Pink Maxi-Mini Carpetrepresentative

Pink Maxi-Mini Carpet

UncommonBeginner

A maxi-mini showing pink to magenta coloration across the disc and tentacle tips, often with a greenish base. Less common than green/rainbow pieces.

Tip: Keep on the sandbed in low-to-moderate flow under moderate, blue-leaning light to hold the pink. Give it space away from corals because of its strong sting; gloves recommended.

Blue/Green Maxi-Mini Carpetrepresentative

Blue/Green Maxi-Mini Carpet

CommonBeginner

A bicolor maxi-mini with a green disc and blue accents (or vice versa) — one of the most frequently available colored forms after plain green. Fluoresces well top-down under blue light.

Tip: Standard maxi-mini care: sandbed, low-to-moderate flow, moderate light. Hardy and forgiving, making it an ideal first anemone; just respect the sting near corals and wear gloves.

Blood Red Mini Carpetrepresentative

Blood Red Mini Carpet

RareBeginner

An uncommon deep blood-red colormorph of the mini/maxi carpet, with a saturated red disc and tentacles — one of the harder solid colors to find in the trade. Reds tend to deepen under blue light.

Tip: Place on sand in low-to-moderate flow and avoid bleaching the red with overly intense white light. Keep well isolated from corals; the sting is potent relative to its small footprint, so wear gloves.

Habitat & enclosure

Suited to **nano and small reef tanks of ~10 gal (38 L) and up** that are well established. Stable water is key: temperature **74-80 F (23-27 C)**, salinity **1.025 SG**, pH **8.2-8.4**, alkalinity **8-9 dKH**, calcium **~420 ppm**, magnesium **~1300 ppm**, nitrate **<30 ppm** (tolerates some nutrients). It usually anchors its foot into rockwork crevices or against the glass rather than free in sand.

Substrate

Prefers to wedge its **foot into rock crevices or against the lower glass**, though it appreciates a **thick sandy area** nearby and may settle at the rock/sand interface. Provide stable rockwork it can anchor into and avoid placing it where it will be blasted off by flow.

Equipment & setup

**Moderate to high lighting (PAR ~150-250)** brings out the rainbow colors. Low to moderate flow — strong flow prevents attachment and food capture. Heater, quality salt mix, and a protein skimmer for stable, clean water. **Screen powerhead/pump intakes**, as even this small anemone can wander into a pump if unhappy.

Diet

**Photosynthetic** via zooxanthellae but an **aggressive eater** — it benefits greatly from spot-feeding small meaty foods (mysis, brine, finely chopped seafood) 1-2x weekly. Its short, dense, sticky tentacles trap food efficiently. Regular feeding supports its intense rainbow coloration and growth.

Behavior & temperament

Mostly sedentary once attached, but **will move** if light or flow is wrong, so kill flow during acclimation to let it grip. **Strong, sticky sting** for its size — it can sting corals and other anemones it contacts and will adhere firmly to fingers, so handle minimally with gloves. Hosts crustaceans like sexy shrimp, anemone shrimp, and porcelain crabs, but does **not** naturally host clownfish. Best kept as a solo specimen with buffer space from corals.

Health

Hardier and better-suited to captivity than large carpet anemones, and many are now aquacultured. A healthy animal is firmly attached, inflated, with a closed mouth and sticky tentacles. **Warning signs:** a gaping mouth, deflating, loss of stickiness, detaching, or fading color indicate stress (poor water, low light, or instability). Remove a dying specimen promptly to protect water quality.

Tips, DIY & hacks

During acclimation, turn off powerheads for a while so it can grab and anchor, then resume gentle flow. Feed regularly to intensify color. Give it its own zone away from corals and other anemones because of its potent sting. Look for aquacultured 'rainbow' specimens, which adapt well and reduce pressure on wild collection.
