トビハゼ（Periophthalmus modestus）は原産地に分布するGobiidaeの淡水魚。成魚は約 11.5–16.8 cm、水温 18–26 °C。
From the waters of muddy coasts of SE China comes Periophthalmus modestus, a member of the family Gobiidae. A benthic percher that spends its days darting between rock, glass and cave — structure decides its temperament. It lives on the bottom. Adults reach 11.5–16.8 cm. Singly or in pairs; every fish needs its own refuge. Caves, stable pairs and clean sand keep this fish far calmer than open, bare tanks ever will. Maintain 18–26 °C at pH 6.5–7.5. A rewarding species for the aquarist who reads before buying.
