Hello! I'm new here and into the tropical fish world. About a month go, I got 3 mollies and 2 tetras. The mollies are 2 female and 1 male. I'm wondering if my females are pregnant. I don't know much so I was hoping I could get some options. The Dalmatian Molly is hard to tell but she looks a bit puffy in her belly. The yellow one looks like she's got a darker area going on... but hard to tell probably in the pictures. Can I please have some opinions? I'm so clueless if they are pregnant, what I should be doing.
