Well, I no longer have a gold nugget pleco. Friday I decided to move the driftwood into my 125g tank since the tannins had all leached out, and that is where I had originally wanted it. The pleco seemed lost with out it in the 29. He would dart all over the place, even with the lights off. So I decided to put him in the 125 with the driftwood thinking he would be ok. I was wrong. Sunday I woke up and he was dead. I don't know who killed him, but there was a small chunk of his underside missing when I netted him out. I am devistated. I don't know how this happened? I figure it was one of the oscars, since none of the other fish are large enough to really do much damage to him (other than torn fins). But even the O's have ignored much smaller plecos and cats that I've introduced to the tank. I just don't know what to think.
