My guppy has appeared to be pregnant going one two months now. I had two fry appear two weeks ago and one more this past week. Not sure if from her or one of my other guppies. But this one just keeps getting bigger. The last two days one of the males will not leave her alone and she has been hiding, which I've notice they do when ready to give birth. But her back end is not turning gray with eyes, but is red. Is something wrong with her? Or is she about to finally give birth?
