Hamster behaviour

[Midi]

Hello everyone I recently purchased 2 very lovely roborovski hamsters, and after thoroughly investing time into understanding them I decided to get myself a pair. (both female)
Now both hamsters have been acting specific ways that in a sense concerns me. As of this moment I have them separated in a large "cage" each.
As I mentioned I have 2 hamsters, one is small and very much docile her name is Pearl and she is super adorable.
The other goes by the name Flurry, she has very dominant and adamant in nature.
Pearl has a tendency of sleeping a lot, like a real ton. I stood up 11:30, I saw they were both asleep in the same hut (pre-separation) soundly.
As I am writing this she is still asleep, but on the other hand Flurry has been "active" and by that I mean she was sitting in the corner of the cage for a while.
I assumed this meant she was awake so I tried to handtrain her while Pearl was still asleep, she decided to bite the tip of my fingers. I can only assume she was one of three. 1. Grouchy, 2. Threatened og 3. Felt lack of space.
This resulted in the separation, as Pearl was still asleep I put on a glove and scooped up Flurry and put her into the large fishtank.
She decided to thereafter nibble on the corners of the cage and try to dig through the floor.
After a while she gave up and went into the hut I had prepared inside the fishtank and is now asleep.
While I have a ton of knowledge, this is my first experience owning hamsters and I am very much a new owner which stresses me out when I am unsure about the health of my dear little hamster.

It's important that once you separate them , they can't be put back together.
Robos aren't easy to tame, they like to be left to it. Yoiu've not had them long and they've already been separated, they'll need time to settle in to their separate homes and adjust. Sometimes hamsters can get stressed with sudden changes.
As for taming, I'd suggest the tissue trick, get some tissues/toilet paper and stuff it up your sleeves and leave for a couple of hours and then place in the cage, do this for both of them and do it often over a couple of weeks, talking softly and quietly also. This will get them familiar with your scent and voice. Try not to stress yourself out, hamsters can sense it.

How recently did you get your robos?
They may still need time to settle in so I would concentrate on just observing them, talking to them so they get used to you being around & doing the tissue trick as Lizzy suggested.
Every ham has a different character so it will take time to get to know your two, if they're still settling into their new home they may be more active when you're asleep & all is quiet for a while so I wouldn't worry about that as long as they are eating & drinking ok.
As Lizzy said now you've separated them they will have to stay apart, as one seems to be quite a dominant character it may be that's for the best anyway rather than waiting for the quieter of the two to get bullied!
