    Cardinal Tetra pregnant?

    So I have some tetras that’s I haven’t had for long and one is looking pretty fat... lol from what I see online it’s hard to tell the male and female apart so I don’t know if it’s a female. And if it is a female I also read it was hard for tetras to spawn in a normal tank?
