The fry are actually pretty close to the same size, I've raised both. Fry feeding and care is the same as well. She's definitely prego. When she drops fry mark a calendar 28-29 days later and she will likely drop again. If I remember correctly they can actually hold sperm and reimpregnate themselves near immediately after giving birth. Those fry can get pregnant at a little over a month old and have their own fry by just over 2 months, sometimes sooner.
