People are not making the approriate differentiation in coral reprduction. Joe had a spawning, where males corals likely released sperm, and females eggs. The big white dots are the coral eggs. These are not baby corals. They need to be fertilized, settle, and then grown. This is very rare in home aquaria, and is actually a testament to Joes tank. What a lot of poeple are describing about their corals is not spawning, but a type of asexual reproduction, likely from fragmentation, or poyp bailout. Pocillopora is well known for polyp bailout, where the coral will "eject" a polyp, it will settle on something, and then grow into a colony. VERY different that spawning. Ask Raj about polyp bailout and pocillopora. His big tank was COVERED with it from this exact event.
