توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
شعاع نرم باله پشتي (کل) : 8 - 10. Distinct line of black pigment midventrally on caudal peduncle absent. Greatest body depth about 2 times in SL. Ventral rays of caudal fin of males not elongated into a sword. Male gonopodium falling short of caudal fin base, without a membranous protuberance, third ray with a strong hook (Ref. 30499).
Body shape (shape guide): fusiform / normal.
Adults occur in warm springs, canals and ditches with typically slow-moving water, silt bottoms and weedy banks (Refs. 5723; 44091, 44894). Also inhabit creeks and swamps (Ref. 44894). Feed on worms, crustaceans, insects and plant matter (Refs. 7020; 44091). Used for genetic research (Ref. 4537). Several color varieties are popular aquarium fishes, where they attain sexual maturity after 3-4 months and reproduce easily (Ref. 1672). Aquarium keeping: minimum aquarium size 60 cm (Ref. 51539).
