It sounds like a good weight
Not too big, not too small, just fine. They do vary in size as SKB says. Our last Syrian was 225g. I went back to the pet shop and asked if they were sure he was a hamster - lol. We used to joke his Dad must have been a guinea pig. Some are much smaller. They can be anything from about 125g to 250g
. But 179g sounds just nice. A nice large hamster but not massive.
