Someone just gave my sister about 12 guppies (2 male, 1 female, and 9 babies), and we have no idea on what to do with them. Currently, all but 4 babies are in a small, filtered container, due to our lack of space. We also do not have a heater for them. The only possible space we could have for them is our 10 gallon tank, but that is already occupied and I kind of want to quarantine them first. We plan to rehome them, but none of the people we have asked so far want any, and online selling is not an option. We would give them back, but the next time we will be seeing the person who gave them to us is in a month. So, what should we do with them, and how should we keep the container warm? Oh yeah, and the female is really pregnant:(
