I just got some guppies and the women in the fish store said they were all boys. But I'm having some doubts about one of them. Is it a girl?
(fancy guppies) One has a bigger tail in width and it's orange. The other one that I think is a girl, is fat like it's pregnant, but she/he has even more colours. She blue yellow and orange. It's tail is smaller in width compared to the boy. The one I think is a boy chases he/she around a lot. Is it a boy or girl? And if it's a girl how long is the gestation period?
