I got one when it was about 2.5 inches he used to hide in the vegetation among the leaves of a large sword plant , then he has moved into a hollow log ornament and I rarely see him. Was feeding early one morning so i left the lighting on moonlight and the sucker came out and was beefy and almost 6 inches now. I hope as he grows he becomes more social and active. Ive thought of removing his cover and see how he does, but I wouldnt want to stress him out. Yours is looking good.
