Saltwater Aquarium/Anemone closing up


I am new to this hobby. I've had fresh water tanks for years. I have a bubble tipped anemone which has been closing up. I'm wondering if this could be a sign that it is going to split....Is that possible????  Thanks Bob

Hi Bob:

If a Bubble Tip Anemone is showing signs of remaining closed up for an extended period of time, it could mean there is a health issue, and perhaps it could be caused by insufficient lighting, water parameters or from not being fed. BTA's should be fed a minimum of 1 to 2 times a week.

However if it's healthy and none of the above are an issue, then yes absolutely it could be a sign that it's going to split. Often times they will split down the middle to make two anemones from one.

Thank you for the question.

I wish you much success with all your future saltwater aquarium endeavors.

I possess over twenty-five years of hands-on experience and knowledge in the ecology of aquariums. Beyond the traditional, I have successfully tested and sustained environments that have been uncharted territories for hobbyists, for decades. I am the first to admit I don't know it all because there will always be something new, amazing, and exciting to learn about, as discoveries are made. It's a hobby one can never outgrow, or grow tired of.

After High School, my experience and love of marine animals influenced me to take up studies in Marine Biology. Throughout college, I studied Microbiology with an emphasis on Marine Life, as well as numerous other sciences. I continued to advance in this hobby, by building a dozen or more saltwater ecosystems all utilizing Microbes as the major source of my filtration method.
