adult length of RTGG

[esoxlucius]

What length can i expect from my RTGG. She's only 6" at the minute. I heard that not all the different breeds of GG grow to the same monster size. In fact i believe the RTGG is the smallest and shouldn't get much bigger than 16", unlike the 20+" of the other kinds. Is this right?

I believe they are the smallest but still get past 20"

I haven't seen them bigger than 20", which doesn't mean they can't get bigger, but even at 18-20" it's still a pretty big and chunky fish. IME, they are not the fastest growers, mine grows a steady 1/2" per month where a gg will easily grow 1-2" per month. GG will comfortably sail past the 24" mark.
