Abstract: The Indian Glass fish, Pseudambassis ranga (P. ranga) (Hamilton, 1822) is popular Indian aquarium fish both locally and globally. The length-weight relationship and condition factor of P. ranga were carried out from East Kolkata Wetland during June 2013 to May 2014. This paper spots the light on the growth coefficient (b) and condition factor. Length-weight relationship and condition factor for a sample size of 595 specimens were calculated. The 'b' value was 2.70, 2.63 and 2.67 in case of male, female and combined sex respectively. Length-weight relationship of P. ranga indicates negative allometric growth and found to be significantly different at 1% level. The scatter diagram showed the linear relationship between the Log length and Log weight of the fish in all cases. The fish does not follow the cube law strictly. The functional form of Length-weight relationship of the species is fitted as Log W= -4.39+ 2.67Log L for combined sex, Log W= -4.43+ 2.70Log L for male and Log W= -4.33+ 2.63Log L for female. The value of the condition factor (K) of the fish is 0.0014 which indicates the poor condition of the fish. The study on the sex ratio showed 1 male: 1.26 female.
