And I have a black Molly that's now hanging out in the bottom corner of the tank... All fat and trading water... I know I made plenty of hiding spots with various sized rocks, full, live plants and decorations and took precautions so that the fry wouldn't get sucked up into the filter. It's been a couple of years since I have had a fish tank and when I did have the other ones I always had tons of fry. And I didn't take nearly as many precautions then as I am now.
Hi Patricia and welcome to AA.
I'm afraid all you can do is wait. I know it's not what you want to hear. They all look pretty big. The signs I look out for is;
Hanging around the bottom and/or the heater.
Her belly starting to square off.
Not eating, or taking some food and spiting it out.
Her anal passage staring to bulge, stick out.
Personally I always use traps. It's a personal preference, some people don't like traps. You have plenty of hiding spots for the fry, so plenty should survive. Another thing I noticed with mine, I have been pretty lucky, that my big guppy mamma usually gives birth during the day. I feed her as she's giving birth, the fry swim right in front of her face and she never eats them. I think it's due to the fact that they usually don't eat for a day or two before the birth and when they do give birth, they are so hungry, that they eat the fry. I could be completely wrong with my theory, but it works for me!!!.
PS... I don't want to alarm you, it could just be the picture, but does the black molly have white spots on her body????
