I have recently bought two dwarf hamsters named Blueberry and Jerry. They get along just fine and I love them so much that I just want more already. I have a 40 gallon fish tank that I keep them in and I also have a separate cage that is coming soon that will be used as a play pen. My boyfriend and I want to get more but do not know if We can have 4 dwarfs living together. I know that I cannot mix species and they are of the same species that I would be getting. We just want more because of they're unbelievably cute and irresistible.
