HAHAHA you all crack me UP! I decided to go ahead and make a terms and conditions, which to my surprise, a ton of members were thrilled about (go figure). Basically what I ended up doing was just referring him to it and telling him to expect people and myself to disagree with him and be prepared to handle it appropriately. He has not responded since yesterday (ROFL). If he decides to keep arguing with me, I am now armed with the scientific info that I need, thanks to you guys. And, you know, now I know myself for future reference. I'm glad I was correct about the plecos, when I first saw him say that I was floored. Thanks again guys, appreciate all of you!!
