Short description
आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण): 2 - 3; पृष्ठीय सौफट रेज़ (सम्पूर्ण): 6-8; गुदा कांटा 2-3; ऐनल सौफट रेज़: 5 - 6. Distinguished from other species by possessing the following characters: upper part of caudal-fin base with elongated narrow dark spot; males with one lamina Canestrini in the pectoral fin, usually broad, axe-shaped; more or less rounded scales with a relatively small central part devoid of cross furrows; Gambetta’s zones of pigmentation are well developed, the fourth zone with relatively small and low 15-28, usually more than 18 spots whose depth is about two times smaller than the horizontal eye diameter (the largest spots on the caudal peduncle are also noticeably smaller than the horizontal eye diameter); the suborbital spine always reaches the posterior edge of the pupil and usually goes further and in small specimens (with TL less than 6.5 cm), usually reaches the posterior edge of the eye; the outer branch of this spine usually (95.5 %) goes as far as centre of eye and often further; head moderately long and deep with a more or less straight profile; 2n=50 (5 pairs of meta-, 15 pairs of submeta-, 4 pairs of subtelo- and 1 pair of acrocentrics), NF=90 (Ref. 78640).
Found in streams with still to moderately flowing clear water, on sand to silt bottom or in dense vegetation (Ref. 59043). Oviparous, possibly with distinct pairing during breeding similar to congeners (Ref. 205). Population is threatened due to a concentrated distribution in a very limited stretch of stream which might dry up in summer (Ref. 59043). Females grow up to a maximum length of 9.1 SL (Ref. 78640).
Life cycle and mating behavior
परिपक्व अवधि | पुनरुत्पत्ति | मछलीऔ का अंडे देना | अंडे | Fecundity | लार्वा
During courtship, 'the male follows the female and, after both enter dense vegetation (e.g. filamentous algae), the male forms a complete ring around the female's body behind the dorsal as the female releases the eggs' (Ref. 59043).
