Fluorescent Pink Anemone
Common Names: Fluorescent Pink Anemone, Pink Bubble Tip Anemone (depending on the exact specimen)
Scientific Name: Entacmaea quadricolor (for Bubble Tip Anemone varieties)
Availability: Available while supplies last — colour and appearance may vary between individual specimens.
Identification
The Fluorescent Pink Anemone is a striking marine anemone prized for its vivid pink to magenta coloration and glowing appearance under blue aquarium lighting. Depending on the variety, the tentacles may develop rounded bubble-like tips or remain more elongated. Individual specimens can change their shape, colour intensity and tentacle appearance depending on lighting, flow, nutrition and overall aquarium conditions.
Behaviour & Role
Anemones are active, mobile reef inhabitants and should be treated differently from corals. They may move around the aquarium until they find a location with suitable lighting, water flow and rockwork. Once established, they can remain in one area for extended periods.
They possess stinging cells called nematocysts and can sting nearby corals and other sessile invertebrates. Give the anemone plenty of space to prevent unwanted contact as it settles into the aquarium.
Some anemones can also host clownfish, making them a popular choice for reef aquariums and clownfish displays.
Compatibility & Caution
Reef Safe: Generally yes, but use caution.
Provide adequate space between the anemone and neighbouring corals. Its sting can damage or kill corals that come into contact with its tentacles. Anemones may also wander, particularly when first introduced, and can potentially come into contact with powerheads, pumps or overflow openings.
Important: Always use appropriate pump guards or protective screens to prevent the anemone from being drawn into aquarium equipment.
Care Level
Moderate to Advanced
A mature, stable aquarium is strongly recommended. Avoid adding an anemone to a newly established aquarium where water parameters may fluctuate.
Recommended Parameters:
- Temperature: 24–27°C (75–81°F)
- Salinity: 1.024–1.026 specific gravity
- pH: 8.0–8.4
- Alkalinity: 7–11 dKH
- Calcium: 400–450 ppm
- Magnesium: 1250–1400 ppm
- Nitrate: Ideally 2–15 ppm
- Phosphate: Approximately 0.03–0.15 ppm
Stability is more important than chasing exact numbers.
Lighting
Moderate to High
Fluorescent Pink Anemones generally benefit from strong reef-quality lighting. Introduce new specimens gradually to intense lighting, particularly if they have been maintained under lower-intensity lighting.
Blue-spectrum lighting can significantly enhance their fluorescent pink coloration.
Water Flow
Moderate, Indirect Flow
Provide enough flow to keep the tentacles gently moving while avoiding excessively strong, direct flow. The anemone should be able to expand naturally without being pushed around continuously.
Feeding
Although photosynthetic, anemones benefit from supplemental feeding. Their symbiotic zooxanthellae provide a significant portion of their energy requirements, while occasional feeding can support growth, colour and overall condition.
Offer appropriately sized pieces of marine-based foods such as:
- Mysis shrimp
- Chopped marine seafood
- Krill
- Quality frozen reef foods
Feed approximately 1–2 times per week, adjusting based on the animal's size and response. Avoid overfeeding.
Tank Mates
Compatible with most peaceful reef fish and invertebrates when adequate space is provided. Clownfish may establish a symbiotic relationship with the anemone.
Avoid aggressive fish or animals that may repeatedly disturb the anemone. Keep sufficient distance from corals, as the anemone's sting can cause significant damage.
Fun Fact
The fluorescent pigments found in brightly coloured anemones can make them appear almost neon pink or magenta under blue LED lighting, making them especially eye-catching in a reef aquarium.
