if they are in the tank with males then more than likey they are. their bellies will take on a boxy type shape and the guppies gravid spot, right above the anal fin, will turn black. when they're not pregnant, the spot is brown.

ok i do have males in there but its been a while since i have seen them like that. should i move them? or should i leave them there? like how can i tell when they are about to give birth?
