Would you want another female or a male? Long fin or albino preferences?
You say big, just meaning adult or are you looking specifically for a larger morph/sub?
I think I can solve your issues if you narrow it down a little and aren't looking for a larger morph.
Feel free to p.m. me and we can figure out a hand off if seems worth the trip to you.
I don't have any fully bristled albinos currently but I've seen a couple getting to close to that age.

I can get a more specific shot of the older juvies if you have specifics in mind. *Due to the albino long fin lineage in my plecos, the "standard" colorations do have white tip tails.
