My dalmation looks pregnant but i just started keeping mollies and would like to know what i have male or female for both the silver molly and dalmation
Here is a drawing on the second pic for better ability for you to tell. You should be able to ID whether it has a gonopodium.

Also check the fish water parameters, they do not look very well. The fins are clamped some, could mean a problem with water and could mean sick fish.
Also read up on fish keeping in my signature thread for the article about keeping Fresh water fish.
Both are females. They will have a black spot in the back of the belly. And start looking very large. If/ when they are pregnant. Don't look like she is yet. Good luck.
