FWIW, I've noticed that if my torch shrinks up for a day or two, and then returns to normal, it pretty regularly means that it is splitting a head into another head. Sometimes they're hard to see if the tentacles are all bunched up, but I've had my torch shrink up for 2-3 days twice now, and each time there is a new head under the tentacles.
Picked up a trumpet/candycane coral (caulastrea) with the war coral, platygyra, and blasto (which I think is dead
) and it's splitting heads really quickly too, and when I fed rods food I saw it catching food and taking it in already. I've never had any problems with caulastreas before. If you look at the 120g tank, on the left side, you can see a head of neon green/cyan caulastrea heads that grew from a single polyp to the size of a softball in 2 years.
It's all about the inputs (light, calcium/alkalinity, and food)!
