I would get rid of the bala shark and goldfish if I were you. Petco was wrong to suggest goldfish, a coldwater species to be mixed with tropical fish. Balas are far too active for the likes of the angelfish and goldfish and will need a longer and bigger tank than an 80 gallons.
With an angelfish, why not buy 4 more angelfish of similar size?:) Ideal tankmates are apistogrammas, severum, blue rams, bolivian rams, corydoras, ancistrus plecos, tetras, pencilfish and hatchetfish.
