Aplocheilus panchax

"A. panchax, the species under present study, was reported to have n=18 and 2n=36 chromosomes by the same author (SCHEEL 1966, 1972) in the Thailand population while the present findings in the India population of the same species differed in having n = 19 and 2n = 38 chromosomes." [1978 Khuda-Bukhsh]

"Purpose of this experiment was to study on distribution and cytogenetics study of Aplocheilus panchax. Ten specimens of A. panchax 2.5-3.5 mm in SL, were used. An observation of mitotic metaphase chromosome prepared from gill, intestine and kidney tissue by the Uwa and Ojima's method (1981) were made. Levan et al.,'s method of chromosome classification was employed. The findings were as follows: 1) Apocheilus (sic) panchax were widely distributed in the Mae Nam Choa Phraya Basin. 2) The diploid chromosome number of A. panchax was 40. The Karyotype consisted of 4 paires of metacentric, 2 pairs of submetacentric, and 14 pairs of acrocentric chromosomes. The arm number was 52. These results will be useful for cytotaxonmy of fishes."

CI2009

Aplocheilus panchax CI 2009 "Manipur" (Glaser). The picture is from 2010 and i kept these "panchax" for some generations. They were quite different from a normal panchax, they were active at 15 and they laid very few eggs, and quite big!.. normally, Aplocheilus panchax is very prolific..
