A dark spot on a guppy's tail could indicate several things, including stress, injury, or a sign of a developing disease. It may also be a natural coloration variation or a marking related to breeding. If the dark spot appears suddenly or is accompanied by other symptoms, such as changes in behavior or health, it is advisable to monitor the fish closely and consider consulting an aquatic veterinarian or expert. Regular water quality checks and maintaining a stress-free environment can help prevent health issues.

Just brough 5 female guppies how do you know when they are about to give birth so we can put them in the baby box?

Look for a dark spot near the tail, slightly above the anal fin of the female. Wait until the spot is a deep dark large spot, and she looks swollen before moving her to your breeder box. The spot you see are all the eyes of the fry, if your guppies are a light color you may be able to make out the heads of a few of the fry. I am assuming you have some males in the tank, if you miss the first batch of fry it will only be a few weeks before the female is pregnant again, and with 5 girls you will have plently of chances. Keep in mind because guppies breed fast, even after you separate the males and females, the females can carry the sperm and impregnant themselves for quite a few more pregnancies.
