It's an albino. There are 3 strains of albino, Tremper, Bell and Las Vegas or Rainwater. Most albinos that come from big pet stores are Trempers but it's really not reliable to tell what strain it is just from looking.
plus if your trying to breed him or her there could always be some hets that you just dont know about. if your trying to breed it i would advise against it because you can muddy the gene pool and that wouldnt be good for the people yousell to. though it might be fine if you breed her for strictly pets
