Here's a couple I have handy as "early shots". You also see a progression from my early shots to my later shots of how my skills with a camera improved, learning how to white balance, hold the camera steadier, and taking top-down shots. Being as most all of my corals started as frags, I really wish I kept better documentation of them, but I did find these.
Both of these I roughly put the time frame on as May 01, 2007
Top is the Tyree Bali Tricolor acro, bottom is known around these parts as "Mr. Ugly's Red Prostrada" (MURP)
Tanks changed, lighting change, flow patterns changed for these next shots, and this made all the difference in the word as far as growth, just remember this next sequence is only about 1 year worth of growth. Oh yeah my picture skills changed
The MURP is obviously visible in the middle, the Bali Tricolor you can see peeking just below the right most branches on the MURP right above the Blue Tort. January 2009
The Bali tricolor is now more pronounced as the Tort got removed, MURP is following flow

October 2009
MURP is now growing on the tort to the left, and is a beast, tricolor while nice in size I'm going to hope MURP doesn't table in all directions and cover that one too. February 2010
So there you have it, a couple coral growth, most of it was over the last year, but as husbandry skills change, you get wiser, your corals will let you know you're doing something right.
