Awesome find, Johnny! I'm on craigslist everyday too. I wish I would come across a deal like you found! Looking forward to following your build thread. If it was me (and it's not) I'd go FOWLR or a densely planted discus tank
Have you seen Pasfur's build thread (video included ) on his FOWLR 180? He's got the most amazing collection of fish in that tank. I love reef tanks but you're so limited on the fish you can keep in a reef.
