RAINBOW DENIZENS OF THE AQUARIUM EAST MEETS WEST IN THE BALANCED AQUARIUM Glass perches, Ambassis lala (two upper), from India swim amiably in the same tank with striped hatchet fishes, Carnegiella strigala,from South America. The former are so transparent that they have little personal privacy. Slightly enlarged. ASPIRANTS TO THE THRONE The pompadour, Symphysodon discus, is urged by some aquarists to replace the scalare as the king of aquarium fishes. It brings individually a top price in the market. The common name refers to the effect created by the dorsal fin. Reduced three diameters.
