well, I've produced many nice spiders with no problems, but I've also produced enough that weren't quite 'train wrecks' but also were bad enough that I didn't feel comfortable selling them. So now, they're mine forever. I felt that the hand writing was pretty much on the wall and I had to ask myself just how many non productive spiders do I want to house? Realistically I probably will breed them again sometime but it would have to be a pretty interesting project. So right now they're a bunch of freeloading rat vacuums.
