Fish - 55-gallon Bowfront community tank

Set up this tank as a community tank and had to move a couple fish over from the Cichlid tank when we lost most of them.  This tank has collapsed (disease), been used as a quarantine tank and then redone as guppy tank.  No matter how many times I say I am done, I just really enjoy having a tank in the living room.  My original plan was to build a large aquarium so I could move Diplo the pleco into it so he could grow full size (2 feet long).  Sadly, the tank collapsed before I could do that.
