Leucistic? When asking a question, it is helpful to explain your terminology. I am not sure what you mean by leucistic. If you mean albinism, in which the pigment of the body and the retina are both absent, the answer is yes. There are numerous species of cave fishes that are albino. If you mean a fish that lacks body pigment but retains retinal pigment, the answer is also yes, but I am only aware of laboratory mutations that display this phenotype (nothing you'd find in a pet store). In the above examples, I am specifically referring to the pigment melanin. So if you are refering to other types of pigment, of which fish have several, then my answers would be different.
