We have had her for a couple months I would say. She has already dropped one batch of fry. She was actually a feeder fish so she was mixed with males. They don't seperate males and females at my lfs in any of their tanks. Her first batch we only found one fry. We had a 20 gallon up and running and had her in it. Then we upgraded to a 46 gallon, put all our fish in the 46, and I killed the heat, air pump, and filter on the 20, and dropped the water about halfway. Well like 2 weeks went by with no air, filter, or heat and we noticed a guppy fry swimming around in the 20. Lol what's the chances of that?
