Hi i bought my guppies 4 of them 2 female 2 male about 50days ago not even one of them has given birt.h nor do they look pre.gnant/big they are dark so its not possible to look for graid spot why are they not breeing? They seem comfortable enough and btw i keep them outdoors in a tub like a outdoor tub pond with lotus plants and some guppy grass

Thanks!
