I don't see anything that makes me think it's spawning (releasing gametes), so I assume you meant to ask if it's splitting?
The photo is too blue and does not really show the coral at a good angle. What specifically are you seeing that makes you think it it's splitting?
Have a picture of any of the torches in your tank? is this relatively close to one? Odd and i can tell it is tiny due to the frag plug in the background. Any other pictures?
