#1. I purchased my six platy's about 1 - 2 weeks ago (not all at once), purchased 5 female and 1 male. It looks to me that at least three, possibly four of the females are pregnant. How long does it take for a pregnant female to show? #2. I'm not taking any special precautions to save the fry at this time, I have a few floating plants and plenty of hiding places, so it's kind of survival of the fittest at this point. My questions is, when the platy have new fry, is this equivalent to "adding new fish" to my tank. In other words, will my ammonia spike like if I bought fish from the store? I don't want to skip a few days of testing my levels to wake up to a 4.0 ammonia reading & a tank full of dead fish because my platys all had babies (even if they do get eaten) Any info is appreciated!!
