Etymology: Tetraodon: Greek, tetra = four + Greek, odous = teeth (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal; pH range: 6.5 - 7.5; dH range: 10 - 20. Tropical; 22°C - 26°C (Ref. 1672)
Africa: reported from "large rivers in the Congo basin" (Ref. 2829), but apparently limited to Pool Malebo (Ref. 41585) or "Leopoldville" (=Kinshasa)(Ref. 41590, 41591).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 9.0 cm TL male/unsexed; (Ref. 2829)
Found in large rivers (Ref. 2829), i.e. not a brackish water species. Feeds on benthic animals such as snails and worms. Solitary, aggressive against conspecifics. Eggs are deposited on leaves and defended by the male.
