You may be alpa to them but they are teenage hooligans challenging each other for dominance , Geting them neautered is important as this will reduce the testosterone levels and make them less likely to fight , it may not be a cure all but it will help a lot . have you tried the rattle bottle and a sharp no when they start , sometimes i wonder wheather keeping them apart only kicks things off again when they finally get close maybe letting them be together but keeping a close eye on them so they dont do too much damage . We have 2 bitch labs they are not direct siblings but we think they have the same dad and they get on fine they have thier moments where they play fight but thats all it is they show teath they pull faces but niether ends up hurt , some days Jess seems to have the upper hand ,some days Daisy does so its swings and rounabouts , get them done asap and then it could be a while for things to cool down but it should get better
