One caution -- albino catfish are not "white catfish" as alluded to in the link Omaha posted. I have white catfish in my pond, however they are not albinos, and only their whiskers, bellies and lower sides are white. White catfish look very much like channel cats, but they are stockier, and they do not grow nearly as big. They are native to streams and rivers that dump into the Chesapeake Bay and the Gulf of Mexico, and a few other places in the south and eastern US.
The albino catfish that I am familiar with are true albinos, and the ones commonly sold are albino channel catfish. They are just channel catfish that are devoid of pigment, just like albino rabbits or deer.
Also, channel catfish generally will not successfully reproduce in small ponds. They are mostly a put-and-take fish unless you have a pond of several acres or more. If they do reproduce, and you have bass, the fry will quickly get wiped out. The young catfish tend to be very slow reacting and they congregate in large "balls" that predators can wipe out pretty quickly.
