Purple Base Green Bubble Anemone: The Hardy Clownfish Host
The Purple Base Green Bubble Anemone (Entacmaea quadricolor), often abbreviated as BTA, is one of the most popular and commonly recommended sea anemones in the marine hobby. This name refers to a specific color morph of the anemone, which features green, bulbous-tipped tentacles and a distinctly purple, red, or maroon foot/column used for attachment.
Native to the Indo-Pacific, this anemone is prized for its hardiness and its reliability as a host for many species of clownfish, including the Ocellaris, Percula, and Maroon Clownfish. It is an excellent choice for intermediate keepers looking for an anemone that is generally easier to care for than other host species.

I’ve had this anemone for three months now and it’s thriving. It’s been hosting my Ocellaris clownfish, and the fish stays close to it without stress. The color is vibrant and the tentacles are healthy and active. Easy to maintain in my 55-gallon tank with regular water changes.

It’s a solid choice for beginners. I was worried about anemones being too sensitive, but this one has adapted well. The green tentacles stand out in the tank, and my Percula clownfish has been visiting it daily. Just make sure the water parameters are stable.

Great addition to my reef tank. It’s grown steadily and has not shown any signs of deterioration. The purple foot is clearly visible and it attaches firmly to the rock. I’ve seen it interact with my Maroon Clownfish, which is a nice bonus.
