Actually smaller frags grow much faster than large colonies...at least from my experince..I’d let it grow out more too. Mainly because once it reaches a critical size it should grow much faster and be no big deal to cut off a couple frags.
What I have seen, small frags that i accidentally break off colonies and glue next to the mother colony grow fast really fast up to a point where they are double or triple size then slow down and grow regular speed as the mother colony.I’ve seen it reported that for any given mass of stoney coral that it will grow faster if you cut it up and have lots of frags. For example if you have a colony and cut it up into smaller frags vs leave it intact. Aside from shading and the issue of growing in all directions vs only in one direction for any given branch, I’m personally not convinced.
But I’ve never seen it reported that a smaller mass of coral like a frag will add new mass faster than a larger mass of coral like a colony, which is the situation here.
Also I’ve experienced and heard from others that an SPS will grow minimally for a long time then quickly accelerate its growth once it reaches some threshold size or maturity.
As much as I love torches I cannot for the life of me keep them happy in my sps tanks. Used to keep them happy back when I ran higher nutrients mixed reefs, but with my low nutrients these babies never seems happy(Do you want to rehome those torches
