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.Flyfisha said: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?
