 i  got  similar  looking  stuff  from  an  LFS.  is  it  really  lava  rock?  is  it  safe  for  a  cichlid  tank.  These  rocks  have  sharp  edges  and  sharp  pin  like  tiny  projections  all  over..    are  these  rock  safe  for  the  fish  or  will  the  fish  cut  their  bodies  if  they  rub  against  them?

 That  does  look  like  lava  rock.  However,  you  should  not  use  it  if  it  has  excessively  sharp  edges.  All  the  lava  rock  I've  seen  has  been  fairly  smooth.

 I  have  seen  similar  stuff  with  a  mineral  dealer,  I  was  fooled  it  was  lava  rock.  I  then  was  educated  and  told  it  was  chunks  of  cooled  slag  from  smelting  copper.
 
 He  was  crushing  these  pieces  to  make  graded  sand  blasting  grains.
 
 It  looks  awfully  impressive,  but  I  have  never  seen  real  lava  rock  for  sale  anywhere  in  India.  Be  careful.

 Lava  rock  is  formed  when  volcano  erupts  and  the  molten  lava  cools  on  the  surface  of  earth.
 A  source  of  lava  rock  will  always  be  an  volcanic  eruption.  I  don't  think  there  have  ben  volcanic  eruptions  in  India  for  a  few  hundred  years  and  as  such  there  might  not  be  true  lava  rocks  in  India.
 Any  original  lava  rocks  would  be  imported  from  Java,  Sumatra,Philipines  etc.  which  are  nearest  regions  of  occasional  volcanic  eruptions.
 Most  of  the  so  called  lava  rocks  would  be  byproducts  of  metullargical  proceses  as  already  pointed  by  Madan  and  Sujoy  "joyban"  in  an  earlier  post.
 Authentic  lava  round  would  have  rounded  edges  as  corrosion  over  a  period  of  time  would  give  rounded  edges.
 Newly  created  rocks  would  have  sharp  edges  &  might  be  chemically  unstable  also.

 These  are  pics  of  Iron  &  Copper  Slag.
 
 http://www.dignubia.org/maps/timeline/bce-0033.htm
 
 Please  see  this  site  for  picture  reference.
 
 Slags  are  nonmetallic  byproducts  of  many  metallurgical  operations  and  consist  primarily  of  calcium,  magnesium,  and  aluminum  silicates  in  various  combinations.    Iron  and  steel  slags  are  coproducts  of  iron  and  steel  manufacturing.    In  the  production  of  iron,  the  blast  furnace  is  charged  with  iron  ore,  fluxing  agents,  usually  limestone  and  dolomite,  and  coke  as  fuel  and  the  reducing  agent.    The  iron  ore  is  a  mixture  of  iron  oxides,  silica,  and  alumina.    From  this  and  the  added  fluxing  agents  molten  slag  and  iron  are  formed.    The  physical  characteristics  such  as  density,  porosity,  and  particle  size,  are  affected  by  the  cooling  rates  and  chemical  composition.    Depending  on  the  cooling  method,  three  types  of  iron  slag  are  produced—  air  cooled,  expanded,  and  granulated.  So  this  may  contain  lot  of  harmful  minerals  which  may  be  released  in  water  in  case  we  keep  it  in  aquarium.  
 
 So  one  should  not  use  it  in  Aquarium.
 
 If  one  is  looking  at  a  Vaocanic  Rock  Formation  to  be  used  in  aquarium,  the  best  place  to  look  for  them  is  in  Deccan  Traps  Volcano  (  Near  Pune)  or  in  Goa  (Vagator  and  Chapora  beaches)  in  India.  Even  Andamans  has  some  Volcanoes,  but  may  be  difficult  to  reach  or  may  be  out  of  bounds.
 
 See  here  :-

 Rift  Valley  In  India  :-
 
 http://upload.wikimedia.org/wikipedia/commons/7/7b/Narmada.jpg
 (Narmada  River  At  Marble  rocks  Jabalpur)
 
 The  Narmada  River,  flowing  into  the  Arabian  Sea  through  a  rift  valley,  marks  a  part  of  the  northern  boundary  of  the  State.  The  other  rift  valley,  of  the  Tapti  River,  also  flowing  into  the  Arabian  Sea,  marks  the  other  part  of  the  northern  boundary.  These  two  river  valleys  are  separated  by  a  horst  known  as  the  Satpura  Range.  
 
 The  Narmada  or  Nerbudda  is  a  river  in  central  India.  It  forms  the  traditional  boundary  between  North  India  and  South  India,  and  is  a  total  of  1,289  km  (801  mi)  long.  It  is  one  of  only  three  major  rivers  in  pensinsular  India  that  run  from  east  to  west,  along  with  the  Tapti  and  the  Mahi  river.  It  is  the  only  river  in  India  that  flows  in  a  rift  valley.  It  rises  on  the  summit  of  Amarkantak  Hill  in  Madhya  Pradesh  state,  and  for  the  first  320  kilometres  (200  miles)  of  its  course  winds  among  the  Mandla  Hills,  which  form  the  head  of  the  Satpura  Range;  then  at  Jabalpur,  passing  through  the  'Marble  Rocks',  it  enters  the  Narmada  Valley  between  the  Vindhya  and  Satpura  ranges,  and  pursues  a  direct  westerly  course  to  the  Gulf  of  Cambay.  It  flows  through  the  states  of  Madhya  Pradesh,  Maharashtra,  and  Gujarat,  and  empties  into  the  Arabian  Sea  in  the  Bharuch  District  of  Gujarat.  (  Source  http://en.wikipedia.org/wiki/Narmada_Valley)
 
 Hope  this  clears  all  the  doubts  about  the  lava  rocks  In  India
 
 
 Regards

 Thanks  joyban,
 that  really  is  very  informative  and  most  importantly  inspiring  to  start  a  hunt  for  the  lava  rocks  esp.  the  last  few  lines!

 There  is  an  active  volcano,  somewhere  near  Port  Blair,  Andaman.
 
 Lava  rocks  are  available  in  limited  quantities  to  tourists  as  souvenirs.  I  wanted  some,  but  as  they  are  heavy,  a  small  quantity  could  weigh  10  to  15  kilos.  
 
 I  dint  want  to  carry  all  that  weight,  so  I  have  decided  I  will  ask  someone  to  carry  it,  when  they  come  by  ship.

 I  wish  to  ask  a  few  basic  questions:  (dont  mind  please)  Smile  
 
 Why  lava  rock?  are  they  good  for  the  fish?  or  do  they  just  look  good?
 can  they  be  used  in  any  setup?

 @  Sandeepraghuvanshi,  IIRC,  the  Deccan  plateau  is  made  of  igneous  rock...  the  famed  black  soil  there  is  mostly  weathered  igneous  rock.  Both  granite  and  pumice  are  formed  from  lava  and  is  mined  in  India.
 
 The  best  bet  for  aquaria  is  to  find  a  pumice  quarry.

 I  think  they  are  mainly  used  for  looks,  they  have  small  irregular  cavities  in  them  which  can  be  used  by  small  fishes.
 I  my  view  the  only  problem  is  that  you  don't  know  their  constitution  and  their  effect  on  water  chemistry.
 If  you  can  et  aquarium  safe  pieces  then  there  is  no  problem.

 i  got  rid  of  those  rocks  sold  to  me  as  "lava  rock"  and  got  pebbles  instead..    i  got  another  huge  chunk  of  rock  that's  got  cavities  and  holes  right  through  it,  but  that  rock's  got  iron  in  it..  any  problems  with  that?

 How  can  you  confirm  it  has  iron.  Where  did  you  get  it  ,  is  it  aquarium  safe.
 If  this  is  your  first  aquarium,  kindly  stasy  away  from  suspious  items.
 You  will  have  enough  problems  with  tank  cycling  or  not  to  cope  up  with  rocks  which  alter  your  water  chemistry.
