Descripción de la especie

Cottidae species Cottus pollux comes from Japan. A benthic percher that spends its days darting between rock, glass and cave — structure decides its temperament. It swims in mid-water. Adults reach 4–8 cm. Pairs or small groups with ample hiding spots. Caves, stable pairs and clean sand keep this fish far calmer than open, bare tanks ever will. Maintain 20–26 °C at pH 6.5–7.5. Undemanding once its core needs are met.
