Are these guppies pregnant?
the first & second picture are the same guppy, the bottom one is the second guppy.
any advice?
ok thanks! i've heard you need to put them in a seperate tank if you can to help them survive?
Another thing to look out for is the black section near the back of her belly. It is called the gravid spot. When I see this in my swordtail, I usually put her ina separate tank.
