Etymology: oophorus: Greek, oon = egg + Greek, pherein = to carry.
Environment / Climate / Range
Freshwater; pelagic; pH range: 7.5 - 8.5. Tropical; 24°C - 29°C (Ref. 31267), preferred ?
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.5 cm TL male/unsexed; (Ref. 31267); common length : 6.5 cm SL male/unsexed; (Ref. 7050)
soft rays: 20 - 22. Distinguished from all other members of the family by the combination of the following characters: jaws subequal, 20-22 anal fin rays, eye diameter about equal to snout length, 33-35% HL, 58-65 scales in lateral row, 8-10 branched dorsal rays (Ref. 26747).
The eggs are carried between the pelvic fins with each egg attached to the body by 10-20 filaments (Ref. 7050).
