They are never stated to be related as siblings, the general consensus is that they are a couple, and they are shown as such more often than not. Their genders are not explicitly stated (as far as I'm aware) however it is commonly thought they are based on Tove and her partner/girlfriend! When it came to Moomin media being created in other countries they were often changed to be a boy and girl instead of seen as two women due to censors, etc, similar to how two women characters in Sailor Moon who were in a relationship were said to be siblings in the dubbing in some countries, due to censorship.
