They are very readily and regularly available to fish shops from suppliers/wholesalers, and I would estimate that 90% of the pet/fish shops that I visit have them in stock pretty much all year long.
Thanks, I'll keep at it. I am not going to settle for any other cory! I don't want to order right now, I live in Wisconsin. They may arrive as frozen fish! I may have to drive to Milwaukee to find them.
I don't see them a lot around here, either...actually, neither of the places I call "here" or "home" have them all that often.
To answer the other question, I do find Pandas to be somewhat more susceptible to illness and they succumb to poor water quality a lot more quickly than other cories that are "common" in the hobby.
Are petstore only gets the basic fish in (Guppies, Bronze Cories, Gouramis, Mollies, ect.). So sometimes I have to order fish that I want. Panda Cories are on the order list about 50% of the time. Why don't you get C. arcuatus or C. metae? I know you said you only wanted Pandas, but both those species I mentioned look very close to Pandas.
