Rainbow Bubble Tip Anemone (RBTA) – Flow, Color, and Clownfish Hosting in One
The Rainbow Bubble Tip Anemone (Entacmaea quadricolor) is one of the most striking and dynamic invertebrates in reef aquaria. It features multi-toned tentacles ranging from red, orange, yellow, green, and even blue under actinics. Its vibrant bubble tips and symbiotic relationship with clownfish make it a showpiece in any tank.
Anemone Highlights:
🌈 Multicolor Tentacles – Red base, orange/yellow midtones, green sheen under blues
🎈 Bubble Tips – Rounded ends that pulse and sway with flow
🤝 Clownfish Host – Natural symbiosis with ocellaris, percula, and other clowns
💡 Lighting: High PAR (150–250) – strong light brings out full rainbow coloration
🌊 Flow: Moderate, indirect – too much may cause it to roam
🧪 Parameters:
Temp: 76–78°F
Salinity: 1.025
dKH: 8–11
Calcium: 420–460 ppm
Magnesium: 1300–1400 ppm
Nitrate: 5–15 ppm
Phosphate: 0.03–0.08 ppm
Placement: Allow the anemone to find its spot on rockwork — it will move until happy
Feeding: Optional but benefits from 1–2x/week feeding (mysis, silversides, krill)
Care Level: Moderate – Needs mature, stable tanks with solid lighting and low aggression neighbors
📦 Note: Frags are not WYSIWYG. Each Rainbow BTA develops its own swirl of colors under reef lighting, with classic bubble tips and healthy footing.
