well i have a dalmation molly, and shes pregnent, but i cant see her gravid spot, as she is covered in black spots, so its hard to tell, anywere in perticular to look?
You can't really see gravid spots on Dalmations. Anyway, just because you can see one doesn't mean she's pregnant, it has to be darkish. All females have gravid spots, pregnant or not.
If you have a male in the tank, 99% chance she's pregnant. Even if you don't, there is still a good chance she is pregnant because they can store sperm for up to 7 pregnancies.
Waiting another month or so will solve the question for you. If she is pregnant, she will have babies, she will know how to deal with that. It's not as if you had to make antenatal appointments for her, or stop her drinking alcohol.
