Species of sea anemone

Bubble tip anemone (Entacmaea quadricolor) is a species of sea anemone in the family Actiniidae. During these times, E. quadricolor will release its gametes into the water column and form free swimming planula larvae.

In aquariums, E. quadricolor will reproduce asexually or sexually when in proper care with supplemented minerals such as iodine and other trace elements, usually purchased as an enrichment cocktail by most home aquarists. E. quadricolor is commonly kept in marine aquariums and comes in variety of colors, green and rose being the most common. Without adequate lighting, the anemone will expel its photosynthetic symbiotic zooxanthellae, a process commonly known as "bleaching" which will progressively result in its death. White or excessively translucent specimens are likely in various phases of bleaching and should not be purchased. Anemones are not easy to keep, and require a knowledgeable aquarist. The aquarium must be at least six months old and stable to receive the anemone. The bigger the tank, the easier it will be to keep a healthy anemone.

E quadricolor is not currently listed on the IUCN Red List of Threatened Species, but it is facing hardships with global climate change and anthropogenic activities. Anthropogenic activities have increased atmospheric carbon dioxide and consequently global temperatures are predicted to raise by 4.3 °C while seawater pH is likely to decrease by 0.3 units. It has been observed that future ocean temperatures will cause bleaching in E. quadricolor, whereas increased p generally had no significant effects on the anemone. Coral bleaching events will have detrimental impacts on host sea anemones and the symbionts as a result of climate change.
