There is a fish food for catfish that includes wood. It is by Sera and is a bit expensive, but very high quality. If your lfs doesn't have it, it is available online and probably cheaper.
I only know of albino BN = ABN's. Is there another albino Plec species? But at 10" it isn't a common BN. Be sure it isn't too aggressive for Cories, let alone small ones. Also, you may have some problem with breeding with Cories and Plecs in the same tank. I found my Cories eat the Plec eggs (at least I assume that is why I didn't have many plecs until I separated them. And the plecs will likely eat eggs.
some small Corys: C. bilineatus "San Juans", melini, arcuatus, pandas
Pandas are the most available usually and very sweet. They lay their eggs on floating plants. Good luck
Green Cories, bronze Cories and most albinos are the same species, C. aeneus. Sterbai and peppers also have an albino strain. C. aeneus is considered a larger Cory.
