Hi! How long have you had your guinea pigs? Ringworm can often start as a scratch wound, as you can see in this guide here. It is sadly not at all uncommon in new shop-bought guinea pigs. Please use good hygiene when handling your guinea pigs. If it is fungal, you should see an increasing balding area spreading around around and then becoming crusty in the next days. Please see a vet in this case. Both guinea pigs will require fungal treatment. You can reclaim the vet cost from the shop by presenting the bill of sale together with the vet bill, provided you have had your guinea pigs up to two weeks, as in that case, exposure infection has happened at the shop.
Here is our ringworm guide:
Ringworm: Hygiene And Pictures
If it has been a full-on intentional bite (which is extremely rare), their would be a noticeable tension and the girls would stay away from each other and usually teeth chatter at each other. Both parties are usually shocked and subdued in the aftermath, as that kind of bite tends to happen in defense and not in aggression. They can also happen in very skittish piggies that are spooked and making a dash for the same place.
Generally, it is more common for shallow scratches to happen, which can come from a misjudged nip or claw swipe. They are understood as such and do not lead to a break-up of the relationship.
