If the female has been in the same tank as a male in the last 2 months she is pregnant. As long as they are both healthy?

Doesn't have to be. In case she's only stored sperm packets in one or more folds of her fallopian tube and hasn't released one or more of those folds, she won't be pregnant. For sperm packets storage is something different than being pregnant. So, if she's mated with a male, doesn't mean that she's pregnant. Only if she releases one or more sperm packets to fertilize the eggs.

You are technically correct emeraldking I don’t disagree.
The natural drive to breed under the right conditions might mean I should have used the words “ when water conditions and food supply is satisfactory “ as well as “ both healthy “?
My impression of most common live bearers is they breed when wet. The OP blackmollylover4life may be asking about a molly after all?
