 Hi  friends,
 
 Today  I  was  cleaning  my  bucket  of  shrimp  tank  kept  in  the  balcony  and  found  each  and  every  shrimp  dead.   Sad   Sad  
 When  i  emptied  I  found  a  copper  wire  (crow  or  piegon  may  be  the  culprit)  
 Does  copper  wire  react  with  water????   I  lost  nearly  60-65  of  them  Sad

 Copper  does  not  react  with  water...
 It  must  be  really  something  else  that  might  have  lead  to  the  wipe  out.
 Was  the  bucket  covered  partially  or  full?
 Sometimes  these  birds  carry  bits  of  food  and  Crows  are  the  notorious  ones  which  carry  stale  left  overs.
 It  might  have  accidentally  dropped  a  small  bit  ,  that  would  have  created  this.

 The  bucket  was  not  covered.
 @  ganessa.  I  agree  with  Vinod.  copper  doesnot  react  with  water.  
 So  was  wondering  what  happened.  Yes  the  2nd  reason  of  left  overs  can  be  the  reason.  
 Learnt  a  BIG  lesson.  Its  was  my  first  time  that  I  had  kept  shrimps.

 Aw  Shucks  !  Sorry  to  hear  that  Ramdas
 
 The  Crows  again.  !!!
 
 Off  late  they  are  poking  my  net  cover  on  my  buckets  which  are  kept  on  the  terrace  and  the  holes  are  getting  bigger
 
 I  want  to  get  a  long  6-7  feet  transparent  acrylic  which  will  act  as  a  cover.  In  order  to  not  fully  cover  the  bucket  so  that  gasses  can  escape  I  can  make  one  bucket  handle  touch  another  bucket  at  the  top  this  ensures  a  gap  is  there
 
 I  plan  to  make  a  scarecrow  with  an  old  black  sock  and  keep  some  containers  of  water  around  open  for  them  so  that  they  get  access  to  their  water.  I  have  already  tied  a  container  in  my  grill  and  fill  it  daily  with  water.
 Right  now  Ive  just  put  a  black  sock  on  a  stick.  But  till  stuff  it  and  stitch  two  buttons  for  eyes.  and  create  a  seperation  of  head  and  body.
 
 A  small  copper  wire  wont  affect.  But  copper  in  the  water  column  does  affect  shrimps  and  is  usually  the  main  killer  if  the  levels  are  not  kept  within  <  0.02  ppm
 
 As  Vinod  says  the  crows  like  to  dip  their  food  in  water  to  soften  it  So  some  of  it  would  have  fallen  in  and  rotted  triggering  an  ammonia  spike

 Sorry  for  your  loss  Ram.   Crying or Very sad  
 
 Copper  wire  wont  make  an  issue,  check  out  other  things  -  I  guess  you  said  it  was  i  a  bucket  -  so  assuming  no  filtration  was  there.
 2nd  what  is  the  water  change  schedule  to  reduce  the  effect  of  bio  load?
 3rd  for  water  change  do  you  use  stored  water  or  direct  -  if  direct  then  sometime  municipal  corporation  includes  heavy  chlorine  which  leads  to  sudden  demise  of  aquatic  creatures.
 4th  as  you  have  said  it  was  an  outdoor  place  so  any  possibility  of  spraying  some  insect  killing  spray,  toxic  spray  etc  etc.?
 
 I  hope  grinding  down  to  these  questions  can  give  you  some  possible  answer.

 1.  (yes  there  was  a  small  sponge  filter)
 2.  weekly
 3.  (dechlorinate  the  water.  have  used  the  same  for  my  fishes  not  problems  there)
 4.possibility  is  food  dropped  in  by  crows  as  pio  said  and  ammonia  spike
 5.  vyas  yes.  maybe  heat.

 Like  abhishek  said...The  copper  would  be  the  last  thing  that  would  have  killed  the  shrimps
 
 1>  Too  many  of  them  ,  possibly  without  adequate  filtration.  How  long  have  they  been  in  that  setup?
 2>  exposure  to  the  elements-  Heat  especially  could  have  cooked  the  shrimps!

 im  a  little  confused,  copper  is  considered  toxic  to  shrimp.im  not  sure  whether  its  copper  salts  or  copper  metal  as  such.  there  are  many  articles  on  the  net  regarding  the  same.
 
 one  such  link:

 Pio  for  a  good  scarecrow  dont  bother  making  it  look  like  a  man.  Just  hang  a  black  garbage  bag  in  such  a  way  that  it  looks  like  a  ghost  (  ROFL  )  and  a  coule  of  CDs  on  strings  where  the  light  can  hit  them

 Biswadeb  agree  to  your  point  but  do  you  think  water  and  copper  wire  will  form  any  kind  of  reaction?
 
 I  feel  if  the  copper  is  in  liquid,powdered  stage  it  can  possibly  react  with  water  not  the  solid  wire..

 @abhishek:   The  below  article  mentions  that  copper  metal  is  inert  and  non  toxic.  only  copper  sulphate  is  highly  toxic.
 
 http://www.aquaticcommunity.com/snail/coppersnail.php
 
 So  i  think  we  should  end  with  the  fact  that  copper  metal  has  no  effect.

 sorry  for  your  loss
 
 There  was  copper  +  you  dechlorinate  the  water.  Did  you  use  a  dechlorinating  agent/solution?  Because  in  that  case  the  agent  may  have  been  sodium  thio  sulphate  which  will  reach  with  chlorine  to  produce  sodium  sulphate  which  can  again  react  with  copper  to  produce  copper  sulphate  (the  series  of  reaction  may  be  a  bit  long  but  i  guess  it  will  reach  there).  
 
 A  far  fetched  idea  but  possible   Very Happy
