Complete Bubble Tip Anemone Care Guide: Tank Setup, Diet, Tankmates, Lifespan
Complete care guide for Bubble Tip Anemone. This article covers everything an aquarist needs to know about keeping Bubble Tip Anemone successfully - from initial tank setup through advanced breeding, with parameter targets, sourcing recommendations, and troubleshooting protocols.
Bubble tip anemone care at a glance
Bubble tip anemone care comes down to three things: strong, stable lighting; a mature reef tank of 30 gallons or more held at 76-80°F, pH 8.1-8.4 and 1.025-1.026 specific gravity; and target feeding two to three times a week. The bubble tip anemone (Entacmaea quadricolor) gets most of its energy from light, so lighting is the first thing to check when one shrinks, wanders or turns pale.
- Scientific name: Entacmaea quadricolor, family Actiniidae, native to the tropical Indo-Pacific including the Red Sea.
- Adult size: up to about 30 cm (12 inches) across.
- Water: 76-80°F, pH 8.1-8.4, specific gravity 1.025-1.026.
- Minimum tank: 30 gallons, mature and stable.
- Feeding: light first, plus silverside, mysis, krill or shelled raw shrimp 2-3 times a week.
- Common colors: green and rose are the most common; orange and red morphs also occur.
- Wild clownfish partners: 14 anemonefish species.
Live listings and the full parameter sheet are on our bubble tip anemone species page, and the rose color form has its own page: rose bubble tip anemone.
Bubble Tip Anemone biology + natural habitat
Bubble Tip Anemone is one of the most-kept aquarium species. Understanding the wild habitat informs every decision in captive care - water parameters, tank size, social structure, diet, and tankmate selection. Browse our full species page for the technical care sheet.
For taxonomic + ecological data, check FishBase + IUCN Red List.
Wild populations have specific habitat requirements that translate directly to captive care. Match the wild conditions and the fish thrives.
Tank size + water parameters
The minimum responsible tank for Bubble Tip Anemone depends on adult size, activity level, and territorial needs. Use our stocking calculator + tank volume calculator for precise sizing.
Use our water parameter checker to score your readings against the species' target range.
Stable parameters beat ideal-but-fluctuating parameters. A swing of 2°F or 0.4 pH stresses fish more than chronic suboptimal-but-stable values.
Filtration + lighting
Use our filter turnover calculator to size filtration. Most freshwater species need 4-6x tank volume turnover; reef species need 20-40x combined return + powerhead flow.
For lighting, use our PAR estimator if keeping coral or planted-tank species. Photoperiod 6-10 hours typical.
Diet + feeding schedule
Diet variety matters dramatically. Single-food diets are the #1 nutritional cause of death after water-quality issues. Rotate 3-5 different foods across each week.
Use our food guides by species for specific recommendations + feeding schedules.
How do bubble tip anemones eat?
Bubble tip anemones eat in two ways: most of their energy comes from light, through zooxanthellae living in their tissue, and they also catch food with their tentacles and pass it to the mouth in the center of the disc. In the wild they also take debris cleaned off their resident clownfish.
In an aquarium, target-feed a piece of silverside, mysis, krill or shelled raw shrimp no bigger than the mouth two to three times a week. Turn pumps down for a few minutes so the food is not blown away. A healthy anemone grabs the food and pulls it in within about 30 seconds; one that keeps spitting food back out is stressed or ill, and the cause is usually light or water quality rather than the food.
Why is my bubble tip anemone splitting?
A bubble tip anemone splits by longitudinal fission: it divides down the middle into two genetically identical clones. This is asexual reproduction. It is recorded as occasional in the wild, while bubble tip anemones in aquariums reproduce asexually when they are well cared for, which is why a keeper can end up with more anemones than planned.
Splitting on its own is not a sign of trouble. Each clone needs its own space, light and food, so if a bubble tip or rose bubble tip is multiplying faster than the tank can hold, let the clones attach and settle, then move the extras to another tank or trade them in. Do not try to cut an anemone that is mid-split.
Tankmate compatibility
Use our tankmate compatibility guides + stocking calculator to plan tankmate combinations safely. Always research adult size + territorial needs before adding new fish.
Common diseases + prevention
The most common diseases include parasites (ich, velvet, flukes), bacterial infections (fin rot, columnaris, dropsy), and fungal issues. Use our symptom matcher to identify diseases + our disease database for treatment protocols.
Prevention: 30-day quarantine for all new arrivals, varied diet, stable parameters, no aggressive tankmates. Use our QT timeline calculator.
Sourcing + where to buy
Choose captive-bred over wild-caught when available - acclimation is faster, immunity stronger, lifespan longer. Top breeders depend on species; browse our originator directory.
For state-by-state legality, check our legality directory. Browse current vendor inventory in our Bubble Tip Anemone species page.
Frequently asked questions
What size tank does a bubble tip anemone need?
A bubble tip anemone needs a mature reef tank of at least 30 gallons, and more room is better because a healthy specimen can reach about 30 cm (12 inches) across. Give it rockwork with a crevice to anchor its foot in, and screen every pump intake and powerhead, because an anemone that decides to move can walk into one. Stable water matters more than the exact gallon count.
What water parameters does a bubble tip anemone need?
Keep a bubble tip anemone at 76-80°F, pH 8.1-8.4 and specific gravity 1.025-1.026, the ranges on our species care sheet. Hold those numbers steady rather than chasing one ideal value, test weekly while the tank is new, and do not add an anemone to a tank that is still cycling or swinging in salinity.
Which clownfish host a bubble tip anemone?
In the wild the bubble tip anemone hosts 14 anemonefish species, about half of all anemonefish, including Clark's (Amphiprion clarkii), tomato (A. frenatus), two-band (A. bicinctus) and maroon (Premnas biaculeatus) clownfish. Ocellaris and percula clownfish are not on that recorded list, so pairing them with a BTA is a captive arrangement that is not guaranteed to take. Our clownfish care guide covers pairing.
Why is my bubble tip anemone turning white?
A white or very pale bubble tip anemone has usually expelled its zooxanthellae, the symbiotic algae that feed it, which is called bleaching. Inadequate lighting is the classic cause, and an anemone that stays bleached loses its main food source and progressively declines. Check that the light is strong enough and has not changed recently, keep target feeding, and hold parameters steady while it recovers color.
