New robos

[Charleen]

I have been researching Russian dwarf hamsters, as that is what I thought I was able to buy. However, once I got to the pet store (I have no breeders in my area at all, closest breeder is 8 hours away), I found out that I could only get Robos. I wanted to try a pair of Russians, but I was able to get Robo sisters. They are about 4-5 weeks old, and while I am looking at things on this site, hamster hideout and good youtubers, I was wondering if anyone has any tips they could give me.

I don't believe they have ever seen a wheel before, and I only have 8 1/2", two of them, so they have not run yet. They also have not had anything to drink, although they did have a water bottle at the store. Should I give some cucumber?

Any tips for such young Robos would be very helpful.

If I can figure out how to post, I will add a picture of Venus, who seems very adventurous (she came out of the travel cage first and came out to explore/find food while I had lights on). Aphrodite is much more shy.
