Oh, I wasn't familiar with them, I just searched by L#. They are pretty cool too. In case you didn't know, john will seperate the pleco's. You don't have to buy the 2 or 3 packs, just email him and he will give you more info. Or you can add more if you want. He is an awesome guy, I have bugged him to death with emails and he has never been anything but nice. Of coarse I'm partial because I'm in FL and get it all shipped for $21
