Sicyopus Discordipinnis Goby

The Sicyopus discordipinnis goby is a rare and vibrant freshwater fish species native to fast-flowing mountain streams in Papua New Guinea. Known for its unique half and half coloration, this small goby is a favorite among advanced aquarists seeking a challenging and rewarding species. Reaching only 3–4 cm in length, the discordipinnis goby thrives in well-oxygenated tanks with strong currents and clean, clear water. Its natural behavior includes darting along rocky substrates and displaying territorial aggression, especially during breeding. This species requires a specialized setup and is best suited for experienced keepers who can replicate its natural habitat.
