My CPDs already started breeding. After doing a 50% water change I noticed 4 tiny fry in my aquarium. Don't want to think about how many ended up in the house plants from the water change. I got them just over a month ago from aquahuna and they came in so small I never imagined they would be of maturity to breed. I wish I hade the time to tend to the fry, I will just have to let nature do its thing.
