I have a question about dumbo rats.... I am thinking about buying a couple female rats to raise up into breeders eventually. I have a 10g tank and I have been doing a lot of reading up on here and I found a person who breeds dumbo rats. She wants 15 dollars each for them which I think is a bit pricey but as I am new to this whole thing maybe not?

Anyway... I am thinking of maybe just keeping dumbos... Is this even a good idea? Is it important to keep other kinds of rats also? I am just wondering.
