Chinese Hamster Gender

[LadyRia]

Hi,
I'm having a difficult time figuring out their genders.
The brown one is named "Sushi" and the white one is named "Snowy". They are both from the same litter and I've had them for a while now in a 60gallon tank with lots of room . Recently, Snowy has been acting weird and has been taking fluff into his hut, hoarding food inside and around the hut and has been aggressive towards Sushi. I tried to get the best picture of Snowy but I'm starting to notice that nipples are coming to be visible, he doesn't like being held right now so that's the best picture I could get. Last night Sushi had it with Snowy that he just put his brother in place (assuming Snowy is a he") .
Please help! I also have a feeling that if Snowy is indeed a girl, that Snowy is actually pregnant.

I’m not entierely sure from the angle of the photo to be honest but male Chinese hams have really obvious testicles if you view them from above or behind you really can’t miss them, I’ve had several Chinese of both sexes & there really is no way to confuse them so I’m sorry to be able to quite decide from your photo!
Either way Chinese hams are solitary & should be kept separately, once they fall out fights can become extremely aggressive resulting in severe injuries or worse so I would separate them immediately, in case Snowy is pregnant I would remove Sushi to the new cage so there is less stress & disruption for Snowy.
Give Snowy lots of substrate & shredded tissue so if she is pregnant then she can build a large nest out of sight, it is very important not to disturb them at all during & after pregnancy. until the babies begin to come out on their own, no peeking or cleaning, just give lots of food.

Edit I just saw your other post & if you’ve had them for 5 months then pregnancy is unlikely as Shannon said there, still important to separate them though.

I can confirm that they're both female.

I would echo Cypher's comment about separating them, Chinese Hamsters don't tend to do well in pairs and can often fight very viciously if not separated at the early signs of problems and females on a whole seem to be more likely to fall out than males.

It sounds to me like the hoarding could be down to a territorial behaviour to prevent Sushi from getting to the food so the behaviour may settle once they're separated however I tend to find that my hamsters that are more inclined to stash food will often stash more in the winter months.

Ahh!! Thank you so much!! I wasn't sure , they told us they were both males and then they started fighting and also it looks like Sushi is starting to develop a bulge so I wasn't sure it that was true or not....I uploaded more pictures just to double check
