I know it's an old topic, but I'm having the same issue right now.
I have 3 creamsicle mollies and one dalmatian/creamsicle/pot bellied molly. I call her Ugly molly. She's so ugly, she's cute.
When the wife picked her up from Paradise Pet's in St.Albert. Ugly Molly was pregnant. She gave birth and at last count we have 16 fry swimming around the bottom of the tank. They range from 1/4" - 1/2" in size right now and Ugly Molly is starting to get fat again. So soon we'll have more.
I'm surprised that any of the fry survived. But my Red Tail Black Shark ignores them as do the Zebra Danios.
I'm going to do my best to separate the males from the females, but that will take awhile. By then I'll be completely over run with molly fry.
Does anyone know of a LFS in the Edmonton area that will purchase the fry for either coin or in store credit?
