Ok so I've had my gt since december (that's almost 6 months) and it hasn't seemed to have grown at all I do 50% water changes a week and all his tankmates have soared way past him in growth and they were all the same size or a little bigger when I got them except my mayan and my oscar they were about 8-9 inches when I got them. Here are pics of him the first one was taken when he was in my 90 gallon and the second is of him in my 125. Sorry for the bad quality of the pics I had to take them with my phone because I couldn't upload the ones on my camera right now
