Many bubble tip anemones lose their bubbles in the typical reef aquarium. Many have speculated that this is due to lighting, the lack of clownfish resident, or even water flow. Some anemones regularly alternate between their bubbled state and that of no bubbles, causing many hobbyists to scratch their heads in confusion. Most of these excuses can be dismissed with a little experimenting, and I’ve found that their bubbling isn’t directly tied to any one particular cause. Sometimes they are stringy with the presence of a guest living amongst the tentacles. Sometimes they are string under both intense and subdued lighting. Seemingly, the bubbles depend on the individual and there’s little to be done to cause them to form if desired.
