Eleotris fusca, a member of the family Eleotridae, is native to southern Chinese coasts and estuaries. Every rock overhang is real estate; give each fish a cave and the tank stays peaceful. It swims in mid-water. Adults reach 14.2–20.9 cm. A bonded pair claims one cave; keep others elsewhere. Provide fine sand or smooth gravel, a cave per fish, and gentle to moderate flow. Maintain 18–26 °C at pH 6.5–7.5. A rewarding species for the aquarist who reads before buying.
