I knew that nitrogen-fixing microbes were a part of corals holobiont, but it’s not something I’ve read into before. This article was a great starter!

Here’s one excerpt from the abstract to get you to click through to the article and read the whole thing:
We show that DDN is assimilated by both the animal host and the endosymbiotic algae. In addition, the amount of assimilated DDN was significantly greater in mesophotic [deep water], bleached, or phosphorus-enriched corals than in surface corals, which almost did not take up this nitrogen form. DDN can thus be of particular importance for the nutrient budget of corals whenever they are limited by the availability of other forms of dissolved nutrients.
