Understanding Blue Acropora: Natural Growth and Problems with Controlled Breeding

Blue Acropora coral species, such as the vivid blue Millepora species can be an essential contribution to the integrity of various ecosystems.
However, just as there are numerous benefits to the growth form and coloring of the various species of Acropora that can actually maintain constant blue coloring, this feat depends on precise factors such as the alkalinity and movement of the water, as well as on the intensity and nature of the light that feeds the corals.

Blue Acropora Health and Influencing Factors

Numerous species of blue corals exist that are associated with the Acropora category. Because of the high levels of natural sunlight, as well as the specific and stable content of elements such as calcium, strontium and other trace elements that need to be present in the water, however, these species are extremely picky about the environment they are able to cope with, and often do not do well in captivity, unless all their needs are met to the smallest detail.
Tropical environments, such as those found in the eastern Indian Ocean and the coasts of Indonesia are ideal for the growth of these types of blue coral.
Here, the amount of sunlight is not only optimal for maintaining the necessary (and stable) levels of lighting and water temperature to allow the corals to thrive, but the overall stability of the ecosystem is also a bonus, allowing for unique species of Acropora to maintain their constant growth in spite of global climate changes.

Loss of Coloring and Other Issues

The somewhat rare occurrence of blue Acropora and its unique properties have made it an object of interests for many scientists across the globe. One of the problems they’ve had with this type of species, however, is that, in most cases, they tend to gradually lose their health and coloring during attempts of growing them indoors in an enclosed environment with artificial lighting.
It has been shown that blue varieties of acropora may actually turn brown and diminish their growth cycle if taken from their natural environments. While light can be one important contributing factor to this, researchers have also pointed out that the delicate balance between water pH and alkalinity, as well as the amount of calcium and magnesium contained by the water can play a major role as well.
Whether or not most species of blue Acropora can in fact be nurtured and influenced to maintain their color, structural integrity and health in controlled environments is still a topic of debate, however, further research in this area can be a significant step forward to clarifying the efforts that need to be made in order to reduce population decline and maintain steady acropora growth in future years.
