Polyp Bailout - Last Ditch Effort by Stony Corals to Survive

When it comes to reproductive methods, corals have a diverse skill set. There is however a much less common method: Polyp Bailout. Polyp bailout is a stress response to unfavorable tank conditions that certain stony corals can activate as a last ditch effort to save themselves. During polyp bailout, polyps are killing off their own connective tissue through apoptosis. I hope you never have to experience it happen in your aquarium, but it is something to be aware of none the less.
