The guy who was selling those large auctions of Zebra Plecos was a fraud. (I believe we're talking about the same auctions.) He never shipped them from Germany, and made a killing by tricking trusting aquarists. As far as I could tell, he created a second personna a few weeks later (Zebrazucht) and did the same thing again. I almost got gypped the first time. Careful in the future!!!!
Plecos in planted tanks are a bit of a tough issue. I'd immediately recommend the albino plecos (no L number), and regular bristlenoses, because these are some of the most vegetarian of plecos. But even these have a tendency to knock out tenuously-planted stems as they scoot around the bottom of the tank.
Carnivorous plecos such as the gold nuggets, and some of the Hypancistrus species (Zebra, King Tiger, Queen Arabesque) somtimes wreak havoc on large-leafed plants (Amazon sword, Anubias especially) because they have quite powerful teeth that tear through the plant and leave tell-tale circular holes. That said, I have Majestic King Tigers (L333), Queen Arabesques (L-260), Orange-Spotteds (LDA-31), and a few other plecos in my 125 planted tank, and I just grin and bear the occasional damage to the large-leafed plants, because they are such darned beautiful animals.
