科: Eleotridae
褐塘鳢为塘鳢科鱼类，温和，但对同类有领地意识，原生分布于中国南方沿海及河口。每块石头都是房产；给每尾一个洞，缸里就太平。成体约 14.2–20.9 cm，一穴一鱼，各得其所则相安无事，适宜水温 18–26 °C。一鱼一洞，万事大吉。
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.
