Correttissimo. Però dice anche:
2) Feeding vs. non-feeding of corals in captivity - yes corals will feed on zooplankton and more meaty food in the case of corals with polyps large enough to take them. No one disputes this. What is in question is do corals in captivity need this? Given that nitrogen, phosphorous and organic nutrient levels are generally several times that found on natural reefs is this enough to keep the corals "happy"? The success of aquarists in Europe with stony and soft corals in the 1970s and 1980s, without any feeding, would tend to support this idea.
....
Dico solo che questo ci deve far riflettere.
