See that's what made it a not very well thought out buy for me lol. I had planned on QT'ing him so that's why I bought him because I figured by the time he was done in the QT tank then the 265g would be up and running and he could go right in. Then on the way home with him I remembered, I have a bunch of BNP fry I got from Jenna over the weekend already set up in the 20g QT tank
DOH! 
. So I don't have much option now but to put him in the Mbuna tank and hope for the best I guess. My own fault, I just wasn't thinking it through very well.
Bag is floating right now, I'll post a pic shortly.
