Ну так про дендронефтию англицким по белому пишут, что это офигенно сложный нефотосинтетик....
"It is extremely difficult to maintain in the reef aquarium, and should be housed in an established reef aquarium, by the more advanced marine aquarist. It requires low lighting combined with medium to strong water movement. It is necessary to have a constant current with an abundance of algal plankton. For continued good health, it will also require the addition of strontium, iodine, and other trace elements to the water.
It does not contain the symbiotic algae zooxanthellae. Therefore, its diet should include live, baby brine shrimp, micro-plankton, and other small foods designed for filter feeding invertebrates, in order to survive in the reef aquarium. These foods must be available almost constantly. Again, only expert aquarists should attempt to keep this coral."
