 Endler's  live  bearers  are  a  offsprings  of  true  strains  that  Endler  collected  way  back  in  the  1970s,  without  allowing  any  corruption/hybridisation  with  guppys  or  other  species,  and  also  between  different  strains/color  morphs  collected  from  different  locations  maintained  by  a  bunch  of  dedicated  enthusiasts.
 
 It's  exactly  like  the  killifish  enthusiasts  who  do  not  allow  cross  breeding  between  the  same  species  collected  from  different  locations.
 Should  you  cross  breed  you  become  the  pariah  of  the  hobby.  I  remember  one  guy  from  Malaysia  who  did  not  maintain  the  purity  of  the  killifish  strain  and  he  was  more  or  less  banned  from  selling  killifish  eggs  or  live  ones.  Everybody  simply  boycotted  him.
 
 So  True  "Endler's  Livebearers"  are  the  pure  strains  of  the  fish  collected  by  Endler  maintained  by  hobbyists  without  crossbreeding/interbreeding  etc.,  etc.,
 
 You  have  to  buy  "Endler's  Livebearers"  from  trusted  hobbyists.

 I  wonder  if  they  are  hybrids?

 Actually  i  think  the  guppy  if  let  to  breed  without  any  interference  for  many  generations  will  end  up  like  the  one  in  your  pictures.  I  have  seen  many  like  that  when  i  used  to  fish  in  a  nearby  lake  a  long  while  ago.
 
 
 Madan  sir  ,  
 Can  the  guppy   revert  back  to  its  original  wild  coloration  if  let  to  inbreed  for  a  very  long  period  of  time?
 
 Please  tell  us  more  about  guppy  genetics  .

 Adip,  I  have  a  whole  book  on  Guppy  Genetics.  Come  and  take  it.

 Oh!  those  are  Guppies  then.  Thanks  Adip.  They  look  great  though.  I'll  keep  them.  They  were  caught  in  a  pond  behind  TNAU,  Coimbatore

 Too  much  inbreeding  results  in  this  kind  of  guppies.  I  have  an  experience.  Once  I  put  about  20   ordinary  guppies  to  an  unused  well  and  after  2  years,  most  of  the  fish  I  found  in  that  well  were  of  this  type.-  Males   with  spots  on  their  body  and  females  with  no  colours.  Later,  I  examined  some  of  the  wells  of  my  friends  and  found  this  happened  there  also.  Many  of  the  guppy  farms  I  know  also  report  the  same  problem.  These  guppies  are  sold  as  feeders.
 I  cant  beleive  that  this  is  another  species-  ELB  or  what  else  it  is  called
 To  the  question,  yes,  this  can  be  reverted  too.  Many  of  the  show  quality  guppies  which  are  sold  without  their  females,  can  be  reproduced  with  colourless  females.  
 Interestingly,  inbreeding  sometimes  produce  another  colour  pattern  in  guppies.  -  yellow  tails  and  spots  resembling  leopards.  I  like  to  call  them  leopard  guppy.This  happened  many  times  to  me,  mostly  in  ordinary,  delta  and  neon  guppies.But  Half  blacks  dont  show  this  behaviour.

 Not  exactly  inbreeding.  The  fancy  guppies  we  keep  are,  if  anything,  heavily  inbred.  
 
 Wild  guppies  carry  most  (if  not  all)  the  genes  for  the  various  forms  we  see  today.  We  select  for  fish  that  express  desirable  genes  to  create  the  various  forms.  
 
 If  you  allow  these  fancy  fish  to  breed  unchecked,  without  selecting  for  any  characteristics  (and  especially  in  an  environment  where  there  is  predation)  the  fish  will  revert  to  the  wild  form  over  a  few  generations,  simply  because  that  is  best  suited  for  life  outside  an  aquarium.
 
 As  to  the  question  re.  ELB  and  guppies,  both  are  very  very  similar  to  each  other.  In  fact,  the  primary  factors  used  in  separating  them  into  distinct  species  are  differences  in  behaviour.  Guppies  are  casanovas.  They'll  chase  any  female  in  the  vicinity.  ELB  are  more  refined,  each  male  accumulating  a  small  harem  of  females  and  sticking  with  them.
 
 There  is  also  a  difference  in  the  way  they  court  females.  Male  ELB  invariably  approach  females  from  below,  guppies  from  behind  or  the  side.
 
 There  are  a  few  other  behavioural  differences  which  I  do  not  recall  off  the  top  of  my  head.
 
 The  above  information  is  for  P.  wingei,  which  I  consider  to  be  the  ELB.  There  are  some  who  argue  this  fish  is  different  from  the  fish  Endler  collected  and  therefore  should  not  be  considered  ELB.
 
 I'd  say  that  the  vast  majority  of  Endler's  in  the  hobby  are  suspect.  Simply  because  they're  very  hard  to  distinguish  from  guppies,  and  there  have  been  several  exports  of  wild  Endler's  (P.  wingei)in  recent  years,  which  may  or  may  not  be  what  they  are  claimed  to  be.
