At a minimum, it is best to stay away from the most difficult anemones in the list above until you are very experienced. These anemones have specialized care requirements, or get very large, or are generally “fickle†in their acceptance of captive environments.
Maximum size: 3 feet in diameter or larger. The 2nd largest of all clown anemones.
Additional info: If unhappy, will move around a lot, climbing up the glass and bothering other sessile invertebrates. Often locates as high in the water column as possible to get bright lighting and high flow. If you don’t have bright enough lighting, it will often climb the tank glass to the surface. Grows fast under good conditions, can triple in size in one year.
All from the resource you gave me. It supports everything I have said. But I doubt that either the severity of its sting or why it is generally not kept in captivity (assuming I were wrong) would result in improper care of this beautiful animal. I did not see you disagree with any of my other points, more relevant to its care. The fact is, its tentacles are tapered, not bulbous. And the tips of its tentacles are bulbous, not tapered. Therefore it is a Magnificent Anemone. Thanks for the apology. Sorry I called you a jerk. I just didn't expect this kind of a response to my 6th post.
To Orion- Thanks for your valued contribution to this thread that will obviously have a significant impact on the care of this anemone. It is not a matter of admitting I am wrong. It is a matter of knowing I am NOT wrong. If you'll notice, I have been a member for many months, but have not posted. I frequent this forum, but generally the few questions I do know the answer to have already been answered better than I could answer. I have been very careful to ensure I am giving other aquariasts accurate and helpful information. I noticed that this thread was misleading it's original poster. My intention was only to help him and his anemone. I wish them the best!
