TIGER GOBY (Schismatogobius ampluvinculus)

A mature tank which should be well filtered with good water movement and oxygenation. The substrate should be soft sand or fine grade rounded gravel, so the gobies can bury themselves and there should also be ample retreats created from rocks, cobbles, pieces of slate and driftwood. Lighting may be fairly bright to simulate the shallow streams of wild habitat. This species is peaceful, so may be maintained in groups. Tank mates should be small, peaceful and able to thrive in the lower temperature.

S. ampluvinculus is capable of dramatic colour change, depending on substrate choice and mood. The specimen pictured here adopted a golden hue to match the silica sand.
