Hello,
You can't stop it unless you separate them. For the record, only Leopard Geckos that are close to being the same size should be housed together. Are they all close in size?
Are you 100% certain they are all females? If any of them are males, he will bite the females behind the neck and around the face as he tries to breed them. (Thats how he shows his dominance and how he subdues the female for copulation.)
Most females will get along with other females just fine. You can always try the other tank, but you could just have a cage bully. (Which sometimes happens.)
