I have a school of three adult, 2-2.5 inch peppered cories, one male and two females.I also have a batch of 3 day old guppy fry one millimeter long. I turned on the light for a second to check on my fish, and lo and behold there was my 2.5 inch female cory in with the baby guppies in the breeder trap. Not a fry missing either. Her mouth is bigger than the fry and they weren't touched. In fact, a baby was sleeping right next to her mouth and was unharmed. I immediately fished her out and put on the lid. Something about my fry must have convinced her to decide to produce eggs as she is now fat with a VERY pink belly! Finally!
