I am sorry if I came across in a bad way or offended you with the petstore part of my post. I didn't mean to. I am not sure where you are located at..most Petsmarts or PetCos have the breeder tanks or the lid clamps for the non sliding lids (you can maybe try ordering from their websites?? I have never done it, don't know if you can order tanks off of there or not). My only other suggestion would be to maybe look on Craigslist for a breeder tank...might be cheaper that way as well.
