I was routinely breeding BN plecos for several years after we moved to Arkansas.  About a year ago, I had to take the tank down, and set it up with new breeders.  Niothing happened.  A few weeks ago, I started losing plecos out of that tank.  I suspected that I might have several males in that tank, and I suspected that the dominate male was killing off his competition.  Today I was looking at the tank, and noticed it was covered with baby albino pleco babies.  Now I've just got to keep it going.    Denny
