Most polys grow about 1"/month given proper care. Most stall in the 6 to 10" range. My dels I've had 4 of them (gave one of my males away... aggression) have all had this growth pattern 1"/month give or take and they stall at about 6" for a bit then start to grow slowly after a couple months. All of mine were cb except the female she came from another member and is wild caught. According to the previous owner she grew about the same 1"/month and slowed down at 8-9" I got her at around 11-12 and she is now 13"ish I've had her for about 3years.
