My female guppy named Bella is my 4th fish after my Betta and 2 other guppies.She has a dark/big gravid spot on one of her sides and on the other side her gravid spot is dark but its not big, and her stomach isnt very big!I have had it for about over a month and when I got it I got it with 2 male guppies but sadly they both died during the first 2 weeks 
in the pet store she was only with female fish so when I put her with the males she was scared at first but later she was ok with being around them.Her stomach is barely bigger than it was before and I really want her to have babies! I dont have a link to a picture of her but my profile picture is of her.Plz help I really want to know if she is pregnant. p.s Im getting triops and was wondering if I can put them with her? Thnx

Also she sits in 1 spot and she eats alot!
