Short description
आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण): 3; पृष्ठीय सौफट रेज़ (सम्पूर्ण): 7-8; गुदा कांटा 3; ऐनल सौफट रेज़: 6. Upper part of the base of the caudal fin with one elongated dark spot; broad axe-shaped lamina Canestrini in males; scales more or les rounded with relatively small central part devoid of cross furrows; Gambetta's zones of pigmentation well developed, the fourth zone consisting of relative large 13-17, usually 16 spots with depth equals or exceeds (the largest spots before dorsal fin) horizontal eye diameter; suborbital spine in females not reaching posterior edge of pupil, but in smaller males reaches as far as the posterior edge of the pupil or some more; the outer branch of this spine usually (85.7%) not reaching the center of the eye; head some shortened and deep with more or less straight profile; karyotype consists of 50 (10 meta-, 30 submeta-, 8 subtelo- and 2 areocentric) chromosomes, the number of chromosomes arms (NF) - 90 (Ref. 57856).
Found in small brooks to large rivers, in flowing or still waters on sand, silt or mud bottoms (Ref. 59043). Oviparous, possibly with distinct pairing during breeding similar to congeners (Ref. 205).

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).
