Continuing research shows that all corals rely on and / or take advantage of a number of food sources in the water column including phytoplankton, zooplankton, bacteria, and particulate organic matter making them polytrophic
BACTERIA
Coral consume bacteria in a number of ways: They can use their mucus and epithelial cilia to snare and consume attached and pelagic bacteria. Some (like Turbinaria species) use cilia to form their mucus into webs which they cast out like a net into the water column to capture bacteria and other particulate matter. The cilia then pull the net back to the colony where polyps consume the catch. Bacteria provide carbon and nitrogen for the polyp and are an important source of phosphorous and other elements for the zooxanthellae. Bacteria are found in very high diversity and biomass on coral reefs, on coral surfaces, and in marine environments. Bacterial levels in reef aquariums are largely unmeasured but are likely to be similar to wild communities and it can be expected that aquarium corals are likely obtaining significant amounts of energy by consuming bacteria on detrital aggregates, in the water column, and grown on their surfaces (see POM).
