Description
Blue gouramis are among the hardiest aquarium fish on the market. A color variation of the three spot gourami, they sport only two spots—one in the center of the body and a second at the caudal pentacle (beginning of the tail). Where is the third spot? It's the eye! Usually silvery blue, their colors change considerably with their moods. During spawning, they acquire a much deeper blue hue. The opaline or cosby hybrid variation lacks spots, has a darker blue marbling, and is rarely available for sale.
