When my gigas was about 5-6 inches or so it put out about 1/4 inches a month.
My previous Gigas died at about this size so I am not really sure how fast they can grow at this age. This clam is 9 years old and is bout 14 inches. From the shell, there are several periord of unclear duration when he is not growing.
Looking at the shell of these large clam, we can see periord of fast growth (smooth shell) and slow growth (ridges rough shell). I still have my old gigas shell. I will see if I can take some pictures of it to provide example. When my clam was with PMD and stop growing back in the early 2000, and fast grow when it recovered. You can sorta read grow history from the shell, like tree rings.

Notice the pld shell receeded because my clam is doing poorly and actually shink in size, and then new shell growth. There is actually a gap that is almost 1/4 inch wide and deep.
The older shell also show several periord where he was not doing well.
This can also be due to Phosphate levels. I've had my Gigas for almost 6 years now as well as several other large clams, and I've found them to make great "phosphate level" testers. Whenever my phosphate levels creep above .07 I can see a noticeable difference in growth even suspending growth when levels get above .12-.13 (ULR Hanna Kit). These PO4 levels seem to have a more immediate impact on Tridacna growth than other stoney corals.

On many occasions, I have clams in contact with various anemones including Haddoni without problem. So much so that I consider clams impervious to stings of anemones. I find out today that this is definitely not the case. I am coming home today from work, getting ready to get out of town to war of the Giants. Gigantea versus Gigas. We have to postpone out trip to AM tomorrow instead of tonight. The Gigantea anemone sting the heck out of my Gigas.
Both of my rare large animals that I cannot loose. I have to juggle around to separate the two. Hope this change will not cause the Gigantea to wander.

Looks amazing and it looks like the LEDs are doing a lot of good.

I only recently change from MH to LED. He was under 400 W MH before. There are areas on the shell that have 3/4 inch growth.
He really does not start to grow until about July.
I will try to document the amount of grow at the same place I took picture of at the begin of August, and a picture of the shell where there is the most growth this weekend.

Picture of my T. gigas growth. 1.25 inches since I put him in my tank in April. He really did not start growing until sometime in July. I guess we can say that this is 6 month grow but really it is only 3-4 months growth. He have to get healthy again before growing. I guess at 18 inches or so they can grow 2 inches or more per year as clearly seen in my tank.
This is near the top of the shell. At the end it is less but there are two ends. The total shell length increase was at least 1.5 inches for the last 6 months.

That clam can make clam chowder for quite a few people. How about tomorrow?
This is a picture taken on 7/31/2013. Quite a bit of growth isn't it? 2 months and 20 days. As accurate as I can , I estimate that the clam is at 17 inches. I estimate by see where the ends of the shell line up with the aquarium wall and measure it. 17 inches and the growth is about over 1 inch since I put him into the tank. He did not start to growth until July 2013.
