Kot­te­lat 1991

First descrip­tion: Notes on the tax­on­omy and dis­tri­b­u­tion of some West­ern Indone­sian fresh­wa­ter fishes, with diag­noses of a new genus and six new species (Pisces: Cyprinidae, Belon­ti­idae, and Chaud­huri­idae). Ichthy­olog­i­cal Explo­ration of Fresh­wa­ters, 2 (1991): 273287

Char­ac­ter­is­tics: Over­all length max. 3.5 cm. Dor­sal struc­ture: XII-​XIII, 67, total 1820, Anal: XI-​XIV, 911, total 2123. ♂ in nup­tial plumage with plain brown-​red col­ored unpaired fins, thin white-​blue lined; pelvic fins have sim­i­lar col­or­ing with whitish to blue medium-​length fil­a­ments. ♀ dif­fer­en­ti­a­tion from other species with a round tail fin dif­fi­cult, usu­ally some­what more extended shape. Courtship col­or­ing of ♀ pale-​beige. The male pri­mary pat­tern is very con­sis­tent, how­ever, for forms with a blue area in the anal fin (see photo G. Kopic), it is unclear, whether they are attrib­ut­able to this species or not.

Sim­i­lar species: risk of con­fu­sion is low, because of the unusual anal fin col­oration of the males, con­fu­sion of the female with some other round-​finned species is possible.

Occur­rence /​Dis­tri­b­u­tion: Kali­man­tan Barat, Anjun­gan area, catch­ment area of the Kapuas River sys­tem, for exam­ple in the black water area of the Kepayang. The close prox­im­ity to the occurence of P. ornat­i­cauda is strik­ing. In some cases both species even live syn­topi­cally, but col­o­nize dif­fer­ent eco­log­i­cal niches.

Threat: High. In the area where this species occurs, wet­lands, espe­cially for­mer moist forests, have been drained and cleared. Many remain­ing waters have been affected by human activities.

Discovery/​First import:

Trade: The species appears occa­sion­ally in pet shops and because it is eas­i­lyrecog­nised, it is less threat­ened by con­fu­sion than oth­ers. It is not rare in trade; the expla­na­tion for this lies partly in the prox­im­ity of the most sought-​after species P. ornat­i­cauda.

Care /​Breed­ing: type local­ity with black water of pH 3.5 to 5.4. In 1990 H. Linke detected a con­duc­tiv­ity of 22 micro Siemens /​L and a rel­a­tively high tem­per­a­ture of 28.3 degrees C. Nests appeared to be built mainly in cave-​like struc­tures of the old leaves, lying in the water. Can be kept and bred well under stan­dard Parosphromenus con­di­tions. Medium-​sized clutches (up to 60 eggs).

Behav­iour /​Par­tic­u­lar­i­ties: usu­ally not com­pli­cated. Head-​down-​courtship. Dif­fer­ent, mostly less dict­inct foam nest. Used to tol­er­at­ing accom­pa­ny­ing fish such as P. R. pauciper­fo­rata osphromenoides from their native habi­tat, but these will pre­vent fry being raised in the same aquarium.
