About 3 weeks ago I started a tank with 7 male fancy guppies. Recently one of my guppies, a green cobra guppy, developed a dark spot above its anal fin, which I read is a gravid spot. What I thought was a male guppy is actually a female and pregnant?! The problem is the gravid spot is visible during the day especially after eating (completely black spot), and then disappears completely in the evening. This has been repeating the last 3-4 days, and I haven't seen any fry drop. Is it really a female? Why is the gravid spot disappearing and reappearing?
