🔥 Redtail Goby (Sicyopterus lagocephalus) – Energetic, Colorful & Algae-Grazing Stream Goby

The Redtail Goby (Sicyopterus lagocephalus) is a brilliant and active freshwater goby admired for its vibrant red tail and iridescent blue body. Found in the fast-flowing, oxygen-rich streams of Southeast Asia and the Pacific Islands, this species is both a stunning visual highlight and a hardworking algae grazer in aquariums. 🌊🐠

Males display intense blue and turquoise hues with bright red or orange tails during maturity, while females are more subdued in tone. Redtail Gobies thrive in clean, well-oxygenated aquariums with moderate to strong current, smooth rocks, and natural algae or biofilm to feed on. They are peaceful, energetic, and best kept in small groups or pairs. ✨
