 I  am  asking  this  question  because  I  am  really  not  certain  what  caused  my  oscar  (7-8")  to  bang  itself  to  the  walls  of  the  tank  and  try  to  jump  out  until  I  switched  off  its  power  unit  for  filter  and  heater.
 I  have  got  the  absolute  cheap  class  chinese  filter  we  easily  get  all  LFS.  and  a  Sobo  heater  300  watts.
 Not  sure  if  this  equipment  is  leaking  some  current  or  if  there  is  something  I  need  to  know  about  the  fish's  behavior.
 Please  share  your  experiences  and  solutions.
 
 Thanks!

 Glass  does  not  conduct  electricity.   Given  this,  a  fish  in  an  aquarium  with  a  live  wire  dipped  into  it  will  not  feel  an  electric  shock  (because  there's  no  earthing  to  close  the  circuit).     In  the  past,  I  have  used  broken  heaters  in  the  tank  with  no  adverse  effect  (of  course,  the  broken  heaters  were  used  for  a  very  short  time  till  I  got  a  new  one).

 +1  on  Shankar's  reply.....spot  on.
 How  often  have  you  seen  your  Oscar  banging  itself  ,  How  big  is  your  tank.
 Are  they  getting  spooked  for  some  specific  reasons  like...
 When  somebody  walks  into  the  room
 When  a  light  is  swithched  on
 When  someone  accidentally  touches  the  table  a  little  hard  on  which  your  aquarium  rests
 How  often  do  you  clean  your  aquarium...reason  I  ask  is...more  frquent  cleaning  never  allows  your  fishes  to  settle  down

 Frequent  cleaning  of  the  tank  does  not  allow  the  fish  to  settle  down.   
 
 Just  a  consideration:   Why  don't  you  provide  the  oscars  with  some  natural  places  to  hide  or  just  make  the  tank  a  little  more  natural  than  a  bare  bottomed  tank?  Some  driftwood,  smooth  surfaced  rocks  etc.?

 Glass  does  not...  but  faulty  electric  connection  can?  I  am  suspecting  that  there  is  a  water  leakage  on  the  cieling,  causing  the  wires  to  go  faulty.  Do  you  think  this  might  be  the  cause?

 My  tank  is  3'  x  1.25'  x  1.25',  fish  is  7-8  inches  in  size.  I  am  not  sure  what  causes  this  behavior,  as  I  have  seen  times,  when  even  the  room  lights  are  off  and  he  starts  going  crazy!  Its  on  the  floor,  so  1  possible  reason  could  be  continuos  distrubance...  or  may  be  not...  I  am  not  too  sure  abt  it
 I  used  to  clean  the  tank  1  every  2  months,  and  weekly  50%  water  change.  In  the  past  nearly  2  months,  he  was  ignored  badly  on  this  front.

 As  just  highlighted,  frequent  cleaning  is  not  done  at  all...  infact  its  now  a  days  being  done  least!

 OK.   One  thing  that  caught  my  attention  from  what  you  said  is  this:  the  tank  is  on  the  floor.   That  def  can  be  the  source  of  your  fish's  discomfort.   
 A)  constant  walking,  thumping  of  foot  can  be  def  felt  by  the  fish.   
 B)  the  fish  always  sees  an  'animal'  peeping  from  the  top,  which  IMO  is  not  liked  by  many  fishes.   I  have  seen  in  other  websites  that  sudden  shift  in  shadows  too  can  scare  fishes.   
 
 Given  this,  the  most  inexpensive  option  for  you  to  try  could  be  to  put  the  tank  up  on  a  pedestal.     You  can  also  try  placing  some  potted  plants  around  the  tank  to  give  more  cover  and  shade  to  the  fish.

 Fish  will  not  feel  shock  as  already  said  unless  the  earthing  circuit  is  complete.

 Actually  fish  will  not  feel  the  shock  even  if  ciruit  is  complete  Very Happy  because  water  stays  at  same  potential  uniformly  around  fish's  body.
 Its  we  who  get  hurt  because  our  hands  will  be  in  some  voltage  and  foot  zero,  so  pHaAtT!!  As  current  pass  through  us.
 
 
 But  if  U  ask  how  electric  eel  jolts  you  down,  that's  something  more  interesting  to  discuss.  Also  electric  rod  fishing.
 
 Anyway  even  I  don't  attribute  it  to  current  leak,  but  either  due  to  ammonia  spike  or  aggressive  fish  or  foot  steps  as  our  members  have  said.
