Found in streams and estuaries. Inhabits slow-flowing water around log snags, under over-hanging banks or among leaf litter (Ref. 5259, 44894). Adult fish migrate downstream to spawn in weedy estuaries from late April to August (Ref. 5259). Feeds on insects, crustaceans, mollusks, worms and fishes (Ref. 5259, 44894). Often buries itself in the substrate to ambush passing prey. A highly efficient osmo-regulator, able to withstand direct transfer from salt to fresh water without any indication of stress. Good eating, but too small to be considered a prime angling target (Ref. 44894).

Trophic level (Ref.
69278): 3.4 ±0.2 se; based on diet studies.
Generation time: 2.8 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilienza (Ref.
