"Its interior becomes blue due the coral's ability to extract iron from surrounding water into a blue salt that is deposited onto the skeleton."

Please in captivity where would this coral get iron from..?

    Although iron is not a commonly added nutrient like calcium and iodine, it can be maintained. Iron has been found to be particularly useful in aquariums with macroalgae, but could also be used by the blue coral if levels are kept high enough. You can read more about this at advancedaquarist.com

I have a colony that is 18 years old. It is growing under bright LEDs with medium flow in a fairly high nutrient tank. It does not like very low phosphate. It this point I have it growing all over my 75 gallon reef and up the back glass. I love it because wherever it is there is no algae 😁

Jellyfish and sea jellies are the informal common names given to the medusa-phase of certain gelatinous members of the subphylum Medusozoa, a major part of the phylum Cnidaria. Jellyfish are mainly free-swimming marine animals with umbrella-shaped bells and trailing tentacles, although a few are not mobile, being anchored to the seabed by stalks. The bell can pulsate to provide propulsion and highly efficient locomotion. The tentacles are armed with stinging cells and may be used to capture prey and defend against predators. Jellyfish have a complex life cycle; the medusa is normally the sexual phase, the planula larva can disperse widely and is followed by a sedentary polyp phase. Jellyfish are eaten by humans in certain cultures, being considered a delicacy in some Asian countries, where species in the Rhizostomae order are pressed and salted to remove excess water. They are also used in research, where the green fluorescent protein, used by some species to cause bioluminescence, has been adapted as a fluorescent marker for genes inserted into other cells or organisms. The stinging cells used by jellyfish to subdue their prey can also injure humans. Many thousands of swimmers are stung every year, with effects ranging from mild discomfort to serious injury or even death; small box jellyfish are responsible for many of these deaths. When conditions are favourable, jellyfish can form vast swarms. These can be responsible for damage to fishing gear by filling fishing nets, and sometimes clog the cooling systems of power and desalination plants which draw their water from the sea.

“Phosphates zero - all corals hate them”. This statement is extremely wrong. Corals need phosphates as they are part of their food source.
