 This  one  is  from  Belur.  I  do  not  know  what  it  is,  I  am  quite  sure  it  is  not  R.  danonicus  and  the  R.  caverii  I  have  seen  are  different  as  well.  
 
 Living  in  stagnant  ponds.  Behaviourwise  these  are  very  close  to  Esomus,  but  then  there  are  no  barbels  in  this  species.  
 
 :-)
 
 Looking  for  enlightenment.  Thanks  for  your  help  
 
 Cheers
 
 Ben

 Ok  let  me  kick  off  the  id'ying
 
 Beta,  It  is  Parluciosoma  daniconius
 
 Reason  for  Id:  
 
 1)  Lateral  line  32  (Brittan  1971,  Talwar  &  Jhingran  1991,  Jayaram  1999)
 2)  14  predorsal  scales  (Brittan  1971)
 3)  Symphysis  of  lower  jaw  on  level  with  middle  of  pupil  (Brittan  1971)
 4)  Fairly  distinct  black  mid  lateral  stripe  edged  with  gold  (Talwar  &  Jhingran  1991)
 5)  intensity  of  the  stripe  variable  can  sometimes  extrend  more  than  opercle  to  caudal  fin  base  (Brittan  1971)
 
 Ben,  it  is  Rasbora  caverii
 
 Reason  for  Id:
 
 1)  Distance  between  dorsal  fin  and  hypural  distance  taken  forward  falls  behind  the  orbit  (Talwar  &  Jhingran  1991,  Jayaram  1999)
 2)  Lateral  stripe  more  prominent  in  the  posterior  half  of  the  body  (Talwar  &  Jhingran  1991)
 
 Balaji,  your  fish  could  be  P.  daniconius.  Not  clear  for  counting.
 
 I  guess  we  need  to  be  flexible  with  colouration  and  body  depth  as  these  are  governed  by  environmental  factors  also  (phenotypic  placticity)  and  we  are  not  dealing  with  clones  Very Happy  
 
 Let  me  quote  from  Brittan  (1971)
 
 "Probably  a  careful  examination  of  a  large  series  of  specimens  from  each  of  the  major  rivers  of  India  will  show  sub  species"  
 
 As  of  now  thats  the  best  of  my  ability..........you  guys  are  welcome  to  improve  on  it  Thumb Up

 I  agree.  Other  than  coloration,  I  don't  see  any  differences.
 Why  are  you  partial  to  Parluciosoma  though?  I  thought  Rasbora  was  still  valid  for  daniconius.

 Beta,  I  do  agree  with  you  that  Rasbora  is  still  valid.  I  was  trained  with  the  name  Parluciosoma   Very Happy     thats  maybe  the  reason  why  I  use  it..

Rasbora  daniconius  complex  Anatomy

 
 
 A-Total  length,  B-standard  length,  C-Dorsal_hypural  distance,  D-Predorsal  distance,  E-Dorsolateral  stripe,  F-Paraxial  stripe,  G-Lateral  line,  H-Dorsal  fin,  I-Caudal  fin,  J-Anal  fin,  K-Vent,  L-  Ventral  fin,  M-Pectoral  fin,  N-Prepelvic  distance,  O-Preanal  distance.
 
 Genus  distinguishing  character:  Parluciosoma(Howes)  or  Rasbora(Day,1878,  Fishes  of  India)
 Body  elongated  and  compressed.  Eyes  large  and  prominent.  No  barbels.  Dorsal  fin  inserted  behind  origin  of  anal  fin  with  nine(seven  branched)  rays,  Anal  fin  with  seven(Five  branched)  rays,  Lateral  line  usually  complete,  distinctive  color  pattern  involving  a  dark  lateral  stripe.
 
 From  here  on  I  will  be  using  Rasbora  as  the  genus  name.
 
 Two  Rasbora  species  have  been  recorded  in  India  as  of  now,  
 1)  Rasbora  daniconius
 2)  Rasbora  cauverii.
 
 Then  what  is  parluciosoma  labiosa???
 
 Next  the  key  to  species........
 
 Regards,
 Nayak.
 
 Note:  Words  in  blue  are  my  doubts.
