Nandidae (Asian leaffishes)
Etymology: Nandus: 'Nandus' is a Bengali local name, but it lacks a proper reference; ‘nanda’ is a Bengali fish name but probably for a different species (J. Müller, pers. comm., April 2021, after information from native speakers); meni: Name after a word of the local dialect of Noakhali, 'meni' meaning an unsuspecting silence character, from where the samples were collected..

Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 13; членистые (мягкие) лучи спинного плавника (общее число) : 11 - 13; колючие лучи анального плавника: 3; членистые (мягкие) лучи анального плавника: 7 - 18. This species is distinguished by the following characters: TL 114.1-142.4 mm, SL 94.1-117.3 mm, body depth at anus 29.0-32.9% of SL, head length (HL) 39.6-42.2% of SL; dark spot on the caudal peduncle; concave ventral portion of the body; gill arch V-shape; body colour , greenish; pectoral fin rays 9-11; snout length 24.5-33.1% of HL; eye diameter 18.1-20.4% of HL; differs from its congeners in body colour, smaller eyes, a concave ventral body, a V-shaped gill arch and a dark spot on the caudal peduncle (Ref. 93873).
This species lives in the freshwater ecosystem of Noakhali and is widely distributed in ponds, ditches, canals, flooded rice fields, swamps, marshes, waterlogged areas and rivers. A very tenacious species that can live in foul water and a surface dweller that consumes insects, algae and small fish. Breeding period varies from April to September. During the study period, the physicochemical parameters were recorded as follows: water temperature 18-28 °C, pH 6.5-7.5, dissolved oxygen 4.5-5.0 mg/l and transparency 45-60 cm for a water body 1.0-1.8 m deep. In the study area, it represents 15-20% of the total Nandus catch (Ref. 93873).
