……… place them labeled as either Trichogaster / Colisa / Badis sp.
This ‘Lot’ has been found frequenting marshy weedy thickets along Suswa river in the Eastern Doon and Asan in Western Doon.
Characterization:
The fishes of this ‘Lot’ have two things in common i.e.,
(a) The presence of a long-based dorsal fin and the presence of spines (spiny rays) in the dorsal, anal and pelvic fins, a characterization of the Order: Perciformes (most diversified of all the orders).
(b) The presence of Ctenoid scales on the body, extending up to behind eye orbit.
Segregation:
This lot can be segregated into ‘2 Sub-lots’, on the basis of diagnostic colourations:
- Sub-lot 1: Brightly coloured (bluish, reddish, golden hues) with dorso-ventrally obliquely running bands on the flanks.
- Sub-lot 2: Drab coloured with dark brown ground colour and more darker vertical bands on the flanks and a black spot covering one full scale just above the base of preopercle.
Sub-lot 1 has two more characters different from the Sub-lot 2 i.e., presence of a long filamentous ray in place of the pelvic fin and a long-based anal fin, too (in addition the long-based dorsal fin).
Identify this Lot ….as species belonging to Genus Colisa / Trichogaster
Sub-lot 2 is different from the Sub-lot 1 in having only a long-based dorsal fin, anal fin being shorter.
Identify this Lot ….as species belonging to Genus Badis as Badis badis
LOT – 8 [SUB-LOT 1]
[Order: Perciformes; Suborder: Anabantoidei; Family: Osphronemidae; Subfamily: Luciocephalinae (Nelson, 2006)]
The sample identified as belonging to Genus Colisa (= Trichogaster) can be segregated into 3 species viz.,
- Colisa lalia (= Trichogaster lalius)
- Colisa fasciatus (= Trichogaster fasciata)
- Colisa labiosus (= Trichogaster labiosa)
For the detailed Taxonomical analysis of the three species pl. refer to research paper entitled, ‘On Colisa sp. from Eastern Doon – Taxonomical Notes and distributional New Record’, Ann. For., 17(1): 125 – 134 (2009)’.

A collection from Suswa [Eastern Doon] at Basanti Mata Mandir (Raiwala) showing trapped specimens of Colisa, Badis, Rasbora and other aquatic biota (Ranatra, Palaemon sp. etc.)
An assemblage of Colisa lalia
Colisa lalia: A characteristic rhomboidal body
Colisa fasciatus (Male): Oval Body
Colisa fasciatus (Female): Oval Body
Colisa labiosus (Male): Oblong (ellipsoidal) Body
Colisa labiosus (Female): Oblong (ellipsoidal) Body
Colisa labiosus (Male): Thick and papillated lips
Colisa labiosus (Female): Thin lips
Colisa labiosus: Kept in laboratory glass trough.
Colisa labiosus: Kept in laboratory glass trough.
Colisa fasciata: Kept in laboratory glass trough.
A glass trough with Colisa sp. in laboratory, seen with bubble foam at the surface, a habit of ‘Bubble nest’ formation, an inherent tendency of all the fellow members like Anabas, Betta, Belontia etc.

LOT – 8 [Sub-lot 2]
[Order: Perciformes; Suborder: Percoidei; Family: Nandidae; Subfamily: Badinae (Nelson, 2006)]
Frequent in the catches with Colisa, Puntius, Danio, Esomus, Rasbora etc., prevalent only at the downstream sections between 300 – 500 m above msl where there is thick growth of submerged and marginal emergent aquatic vegetation.
Body, oval, laterally compressed. Mouth small and upturned. These drab coloured fishes, with dark brown ground colour have darker vertical bands on the flanks and a black spot covering one full scale just above the base of preopercle. They have a long-based dorsal fin but anal fin shorter (in contrast to Colisa sp.). Lateral line (interrupted just opposite the end of dorsal) placed high on the body.
Badis badis
Badis badis: Lateral view
Badis badis: A dark coloured specimen with too dark a ground colour for any bands to be visible. Lateral line (interrupted just opposite the end of dorsal) placed high on the body.
Badis badis: Drab coloured, with brownish ground colour, having darker vertical bands on the flanks and a black spot covering one full scale just above the base of preopercle.

The Favourite Habitat for Colisa and Badis sp.
Suswa River (Eastern Doon): A marshy stretch inhabited by Colisa, Badis and other smaller species like Puntius, Esomus, Rasbora and bottom hiding Channa sp.
Song River (Eastern Doon): Weedy marginal zone at Golatappar (Teen Paani), the dwelling site for Colisa, Badis and other smaller species.
