ECC Nexus Blaze Bubble Tip Anemone — photo 1

The ECC Nexus Blaze Bubble Tip Anemone brings serious color with bright orange tentacles and a glowing green center that pop under reef lighting. Like other BTA varieties it can host clownfish, settles into rocky crevices with moderate lighting and flow, and needs a mature, stable tank with space away from corals and powerheads.

Quick facts

Handling caution: Stinging tentacles can cause skin irritation and will sting other anemones, corals, and unprotected skin on contact

Care guide

Overview

A mid-sized bubble tip anemone that reaches roughly 2 to 12 inches across, with bright orange tentacles surrounding a glowing green oral disc and center. It settles its pedal disc into rock crevices, can host compatible clownfish, and needs moderate lighting and flow in a mature, stable reef away from corals and powerheads.

Care

Bubble tip anemones need a mature reef system, at least six to twelve months old, with stable water chemistry and no measurable ammonia or nitrite. They settle their pedal disc deep into a rock crevice and generally stay put once established, though they can walk to a preferred spot if lighting or flow is unsuitable. Moderate to high lighting and low to moderate flow suit most specimens, and calcium, alkalinity, and magnesium should be kept within normal reef ranges since the anemone hosts photosynthetic zooxanthellae.

Feeding

Offer chopped fish, shrimp, or marine worms two to three times a week using a feeding stick or turkey baster to place food directly against the tentacles. A resident clownfish will often feed the anemone scraps and deposit waste nearby, reducing the need for target feeding, but unhosted specimens should be fed more deliberately. Avoid overfeeding, since decaying food trapped near the oral disc can foul water quality and stress the animal.

Tank mates

Give at least a few inches of clearance from corals and powerheads, since the sweeper tentacles sting anything they contact and the anemone can drift until it finds a spot it likes. Multiple bubble tip anemones should not be placed close together because they can wage chemical warfare on one another. Pairing with a compatible clownfish species benefits both animals, but the anemone does not require a fish to survive.

Breeding

In captivity, reproduction is almost always asexual through pedal laceration or binary fission, where the anemone splits into two genetically identical individuals once it reaches sufficient size and health. This process can happen unpredictably in a well-fed, stable tank and often yields several clones over time. Sexual reproduction via broadcast spawning is documented in the wild but essentially never observed in home aquariums.

Health

A shrinking or deflated anemone that fails to fully expand under normal lighting often signals inadequate light, poor water quality, or insufficient feeding. Bleaching, or a marked loss of coloration, indicates expulsion of zooxanthellae and usually points to a lighting or temperature problem that needs prompt correction. A anemone that repeatedly detaches and wanders is signaling dissatisfaction with its current placement and should be allowed to relocate rather than forced to stay put.
