You should be able to keep at least 150 guppies in a tank that size. Most of them will be fry and immature young juveniles so they won't be the bioload of adults. The other unasked question that needs an answer is that you can keep exactly zero until the tank is cycled. If you are not very familiar with cycling a new tank, please follow the link in my signature area to the thread on "fishless cycling".
Hi there,as long as the media,filter and some of the water from the mature tank are swapped over and filter running very quickly the cycling process should be reduced but to put such a load on your biofilter straight off is asking for trouble...... the problem with mature media is the beneficial bacteria will start to die off in a very short time if there is no water and oxygen flow through it.... when this occurs u'll be left with ammonia and poorly fish. on the topic of your last question a ratio of 3 or more females to one male would be ideal but they will breed like rabbitsYou should be able to keep at least 150 guppies in a tank that size.
