Common pleco :( Keep in mind that these fish get huge--possibly 1-2ft long. They are peaceful, but they can be territorial. If you added another pleco they would probably fight.
If it were me, I would get a large school of pygmy cories or kuhli loaches, and perhaps a large peaceful school of fish like zebra danios or similar.
ADFs are pretty difficult to manage in the aquarium--they are nearly blind and hunt for food by smell. This means if you drop the food in, all the other fish are going to get it before the frogs even realize what's going on. When I had an ADF, I had to put my whole arm in the tank and dangle a live blackworm in front of the frog's nose for 30 seconds until he jumped up and got it. ADFs also like to be in groups.
