Question about swordfish

[Carl]

here is my question

i have had some swordfish for a long time about always having young the problem is aload of young ones there have had are till in my tank and now 1 of my big female who has young all time is turning into a Male ( Shes starting to get the Tail extention ) i wonder if there is anyway i can stop it from happening ? as shes like 3 1/2 inch and all females left are like 1 and half inch apart from it's mother which is more like 4 inch and really don't want it to change ?

Probably best to have one less female if they are breeding like rabbits.

onlt the 2 big ones are breeding other's are all to small really yet and these are my Fav because of size and everything

Plus a lfs is takin aload of me because i said there can have as many as there want because i am over run so there all going soon hence wanting to keep her female
