Thats what I was hoping when I bought the 2. I have the same delemma as you two do, I now have a 180 reef and would like to get a mate for my other one. I was reading the other day, I think it was Indland Aquatics, and they had these tank raised with both a single price and a pair price, I don't think that meant a mated pair but it might have. With my situation and Alice's, we would have to get a single and then see if the one we have has decided the entire tank is his. I will try to keep you two informed, please do the same for me.
