lia corals is 70–120 w/m2. Australian Echinophyllia corals prefer a range of 20–50 w/m2 and favor
spectrums within the 420–460 nm range. Exposure to excessive light can result in rapid tissue atrophy,
causing large portions of flesh to detach from the skeleton. In such cases, as an emergency measure, a
short dip in a saltwater solution mixed with amino acid, such as Elos Omega Amino Acid, can help the
coral absorb the nutrients it requires to survive directly through its tissue.
Since light is not always readily available to them in the wild, Echinophyllia corals have learned to
benefit from the high level of sediment that settles down on them from the current. They are able to
use sediment as a source of nutrition by selectively extracting organic matter and transferring it directly
to their tissue. Once the sediments are depleted of nutritional value, the corals use their natural sedi-ment-rejecting ability with mucus to clean their surface for the next batch. Though it is not necessary,
Echinophyllia corals benefit from occasional direct feeding in a captive environment. They will readily
consume fine particle food, such as CYCLOP-EEZE®, and meaty foods like frozen mysis shrimp. Direct
feeding even once a week can make a significant difference in the growth rate of an Echinophyllia coral.
It has been reported that corals of the Echinophyllia genus have spawned in captivity, but the most
common form of propagation is through “fragging,” whether it be for commercial or aquaculturing
purposes. A razor blade, a diamond wheel saw, a band saw, or even a chisel and hammer can be utilized
to “frag” corals, depending on the shape of the colony and the density of the surface it is encrusting.
The best tool to use is a band saw, due to its accuracy and efficiency. In order to ensure a higher probability of success, it is best to respect the pattern and space of existing corallites on the colony when deciding where to cut. Just remember that when performing surgical procedures on a live animal, a swift,
single cut that is carefully planned is better than repeated failed attempts. After the cut is made, briefly
