Yeah, that's exactly what I think too.

I have not sexed Diego yet. I'm not sure if it's a he or she. The head size looks a little small in comparison to the body similar to my larger girl, Frieda. On the other hand, it looks like there may be jowls forming and Diego is still young and smaller than Frieda.

I did compare Diego with some pics of Extremes from the Chocoan Giant forum and he definitely shares very similar markings. Here is an example of one of Bobby's I believe next to Diego. The top one is one of Bobby's (I think it's Bobby's) that was posted on that forum. The rest of the pics are of Diego.

Regardless of what he is that is one great looking tegu which is all that matters. Looks like a male to me but its just a guess, when they are that heavy at that size its so hard to tell by looks.

Yeah, DEFINITELY a score for a PetCo pickup!

Diego was the first tegu I ever really saw. I saw him while getting crickets at PETCO. They never have tegus usually but they had gotten two in and had sold the larger of the two. I picked up Diego for about $80 with my online coupon. He was always sleeping at first and went into hibernation / brumation for about 11 months straight. I was really concerned because last summer, while Frieda was active, Diego refused to come out of hiding. Of course, I had him inside under lights and not in his outdoor enclosure like I have him now. Since putting him outside he's probably tripled in size. I think the diet of chicken necks has helped too!

Speaking of which, Frieda is now walking correctly. She no longer slides her body but rather walks with her belly and tail held off the ground. I am positive it was the chicken necks because prior to this, she was not walking this way. I really do think she was lacking the calcium and phosphorus because she's always been in the outdoor enclosure getting full sun whenever she wants. What a difference the necks have made. She's also grown substantially too this summer - is getting close to her mate, Kimo's size. She's also more active than she had been previously.

Today, I'm going to move the two big guys into their new cage and transfer Diego into their old one. I'll take some pics as soon as I finish.

By the way, Tegu diversity is just amazing. I was at a great pet store in Fountain Valley, near Huntington Beach, CA called Prehistoric Pets, and they had a bunch of tegus there. Each one looked so different from the next. Quite an amazing amount of diversity in patterns, sizes, etc. They also had a ton of different monitors and some huge pythons big enough to eat my kids.
