Axolotl Gender?

[Aikeler]

Hey guys my Axolotl has grown so much! He's such a cutie. But I wanted some other confirmation of his gender…he seems to be a boy from what I have observed…but I could be wrong I am not a Axolotl expert so I wanted some other opinions. I have attached some photos of his "bump". (and also just some other cute ones because he's freakin adorable and I wanna show him off )
(yes he is a part time model)

How big is he? He doesn't look big enough to sex yet, they really need to be 8" or more, but even after that they can surprise you.
That bump is pretty ambiguous, females also have a small bump, young males do too.

Is that Randall!? Every few weeks I look him up on youtube to see how he is doing for some silly reason. I think we got our axolotls at around the same time and I was searching for videos on chillers when I first saw your aquarium. Very cool. Let's hope he is a boy otherwise that would be awwwwwkward.

Yes it is Randall I haven't made a new youtube video of him lately I think I will soon though since I am off for the holidays and have some extra time! He's going on about 6 months old How is your axolotl doing? I'd love to see some pics!
