All domesticated rats (pets and feeders) are considered fancy rat, no matter the color or markings.
A dumbo rat has bigger ears and different ear placement.
A rex rat has curly fur.
A double rex rat has patches of very short hair, another curly mutation.
A hairless rat has no fur.
I’m attempting to intro two big colonies. One that is 13 adult rats with 11 younger rats. The 13 are Julia, Noodle, Sara, Fleur, Minou that are all 18 months old. Jet, Jude, Jack, AnnaBanana, Sheela, Blue, Bunny, Roxanne they are all 15 months old. The group of 11 are Echo, Rocher, Matou, Darcy, Bug, Fox, Bronco, Pony, Sawyer, Benjamin and Desmond, they are all 5 months old.
Things are going as to be expected… keep in mind, all my females are spayed so no babies here. 
I’m really hoping they become friends, even though they will probably never live together… this will allow them to have 2 to 3 hours of out time daily which is very important to rats.
Wish us luck!
