here is a quick flick of my tuxedo guppie breeding setup i get around 30-40 babies every twenty days. but i have sold alot of the fry for some nice quick money to save up fro some tropheus. i recommend a 30-50 litre guppy breeder and a bigger one for the fry for maximum growth. feed them high protein food eg decapsulated brine shrimp or live food or freeze dried brine shrimp. keep at 25-26 degres and every second saturday up to 28 then lower on monday in this time you will notice them breeding a lot more try it also do a 5-20% water change three times a week this really helps growth.
