Hello! I have 3 female platy fish living with a male platy, and one of the females is very very large. Could someone please help identify if this is a pregnancy, and if it is when she will give birth? I have had pregnant fish but I miss the minnows and they get eaten The male is aggressively chasing her around today and she often hides. Here are some pictures, for some reason the camera makes it look like the water is acidic green!
