This tank is so relaxing to look at, even on the web! After such hard work, it really is a shame to tear it down, and your poor fish! To be relegated back to the LFS after such a nice home they have now!
I think you should just buy a new tank and start fresh with that! Cichlids give a different type of enjoyment, and like having two dogs each of your tanks have their own singular personalities!
I already know your response, University is taking all of the money! I would try hard to get a second tank though. Just think, someone else can't possibly take as good care of your fish as you did!
