Flathead gudgeon (Philypnodon grandiceps) fish species information

Scientific Name
Philypnodon grandiceps

Common Name
Flathead gudgeon

Biology
Found in still and flowing waters; often abundant in dams and lakes, usually among weeds or over mud bottoms. Occurs in reservoirs and brackish estuaries, less common in gently flowing streams (Ref. 44894). Feeds on crustaceans, insects, other fishes and tadpoles (Ref. 44894). In breeding season (mainly spring to summer), males darken and display more vibrant fin markings. Females lay a clutch of eggs on a hard surface such as a rock or piece of wood. The male cares for the nest, chasing away intruders and fanning the eggs with his pectoral fins. Hatching occurs after 4-6 days (Ref. 44894).
