Crazy Female Guppies

[crazyguppy]

hey guys!
i started a tropical aquarium a few days ago... i've always had goldfish until now... so i'm a bit unaware!

i have 5 female (3 of which i suspect are pregnant) and 2 male guppies, some neons and corys.

my red tailed female guppy has been chasing the other guppies, inc males away from her and around the tank whilst nipping. whilst the other female guppies, when not being chased by the red one.. seem so swim alone, swat each other away and stick their heads in the plants i have floating on the top of the tank.
the red guppy doesn't seem to bother any of the other fish in the tank, only the other guppies.

is she aggressive because she's pregnant? please help!

Hi there CrazyGuppy. She may be close to giving birth. Some guppies can definitely start acting like loners when they get close to a fry drop.
