Select options Red Eye Red Spot Green Discus (Symphysodon aequifasciatus) – Wild Nanay $179.99 Long considered the most beautiful of all freshwater aquarium fish, the discus remains a popular fish for serious hobbyists. Regular, large water changes, a protein-rich varied diet, and warm water temperatures (78-84) will create ideal conditions for discus to thrive. Wild discus like the Red Spotted Green are more sensitive to water quality and are best kept by experienced hobbyists. They will do best in soft, slightly acidic water and may take weeks or even months to display their optimal colors in an aquarium but will reward patient aquarists with spectacular coloration and natural behaviors. These specimens originate from the Rio Nanay in Peru and have been selected for good body shape, red eyes, and full red spotting throughout the body.
