I agree with the you on Danios and about most of the common Corys. I think most people by Corys as a utlity fish (good bottom clear).They are active enough but other then price why not get one like a Panda Cory, at least they are something nicer to look at. I never thought I would get Gouramis until I saw a Dwarf Blue and the Dwarf Flame. I got them to add colour to the tank an have found them to have a lot of character (like angels). The DF die of an inherent disease that comes from being mass produced. Black Tetras don't do anything for me. Plecos ... spend the extra $ and get a nice one. I've got a Gold Nugget, about 4 months ago and other then peaking out of his "cave" and bolting as soon as he sees me, I've seen him for about 2 second out of it. That is the honest to god truth! I have tried even to see him at night with a flashlight ... no luck. I think he hears me coming. Maybe a plain one would have been more exciting! Gold fish (comets) are the cows of the fish world and are great to cycle aquariums. The intentionaly bred deformed ones do nothing for me. To each his own I guess.
