 Galaxy  rasbora,  Microrasbora  sp.  Galaxy
 Matt  Clarke  explains  how  to  keep  and  breed  the  newly  discovered  Galaxy  or  Fireworks  rasbora,  Microrasbora  sp  Galaxy  -  a  species  now  under  threat.  
 
 
 Copyright  Â©  Practical  Fishkeeping
 
 
 Common  name:  Galaxy  rasbora,  Fireworks  rasbora,  Rasbora  toei,  Celestial  pearl  danio
 Scientific  name:  Microrasbora  sp.  "Galaxy".  Currently  being  described  and  due  to  be  placed  in  a  new  genus  shortly.
 Origin:  Myanmar.  The  supplier  wanted  to  keep  the  exact  collection  locality  under  wraps  for  commercial  reasons.  It  was  eventually  discovered  to  be  a  micro-habitat  wetland  area  east  of  Inle  Lake.  
 Habitat:  According  to  the  exporter,  his  species  lives  among  dense  vegetation  in  a  cool,  high-altitude  wetland  region  in  a  marsh  area  fed  by  a  spring.  It  lives  in  sympatry  with  Danio  sondhii  and  the  undescribed  Rosy  loach,  Yunnanilus  sp.  
 Diet:  Early  reports  suggested  that  the  fish  might  only  consume  tiny  live  foods,  so  most  people  have  been  feeding  theirs  with  live  Daphnia,  brineshrimp  or  microworms.  However,  most  have  reported  that  these  will  also  accept  small  dried  foods  such  including  Tetra  Mini  Granules  and  crumbled  flakes,  as  well  as  live  Tubifex.  
 Size:  A  miniature  species  that  is  believed  to  be  fully  grown  at  around  1.5cm  in  length.  However,  there  are  some  reports  of  the  fish  reaching  up  to  3cm.  
 Water:  Lives  in  moderately  alkaline  water  with  a  temperature  of  around  24C  or  less.  Collectors  have  claimed  that  the  water  in  the  collection  locality  is  at  pH  7.3  with  a  hardness  of  7  GH  (235  microsiemens).  They  seem  very  adaptable.  Some  of  the  Singapore  fishkeepers  who  were  first  to  obtain  the  species  reported  success  in  keeping  them  in  small  blackwater  tanks  with  a  pH  ranging  from  4.5-5.7.  In  the  UK,  they've  happily  acclimatised  to  our  harder,  more  alkaline  water  without  problems.  
 Aquarium:  Due  to  its  tiny  size,  this  beautiful  little  cyprinid  would  be  best  in  a  small  aquarium,  away  from  larger  fish  that  might  look  upon  it  as  a  tasty  snack.  You  could  keep  an  impressive  little  shoal  of  these  in  a  tiny  desktop  aquarium  such  as  the  AquaCube  we  gave  away  with  last  month's  Practical  Fishkeeping  subscription.  No  details  on  the  habitat  are  available,  however,  aquarium  observations  seem  to  suggest  that  the  fish  likes  well-aerated  or  flowing  water.  Most  fishkeepers  are  keeping  theirs  in  small  planted  aquariums,  in  which  the  species  is  the  only  inhabitant.
 Notes:  New  fish  don't  come  much  newer  than  this:  the  species  was  only  discovered  a  few  weeks  ago  (August  2006)  and  was  first  introduced  by  Kamphol  Udomritthiruj  of  Thailand-based  exporter  AquariCORP.  The  first  specimens  arrived  in  the  UK  during  September.  Practical  Fishkeeping  was  the  world's  first  magazine  to  break  news  of  the  species.  
 Conservation  status:  Sadly,  we  reported  in  February  2007  that  Udomritthiruj  had  visited  the  type  locality  and  discovered  that  other  collectors  had  gone  to  the  area  and  fished  it  so  heavily  that  catches  were  down  to  just  a  few  dozen  specimens  per  day.  The  conservation  status  of  the  species  now  looks  bleak  and  we  would  advise  all  fishkeepers  to  avoid  this  fish  unless  they  have  the  skills  to  breed  the  species  in  captivity.
 Identification:  Undoubtedly  a  new  species  but  only  tentatively  considered  a  Microrasbora  due  to  its  resemblance  with  Microrasbora  erythromicron.  Unlikely  to  be  confused  with  anything  else,  given  its  striking  appearance.  It  is  due  to  be  placed  in  a  new  genus,  along  with  M.  erythromicron,  later  in  February  2007.  
 Sexing:  Quite  simple  to  sex  when  the  fish  are  in  good  condition.  Males  are  brighter  coloured  and  have  bright  red  fins  with  squiggles  of  blue-black  in  the  dorsal  and  anal,  and  the  upper  lobes  of  the  caudal  fin.  The  chests  of  males  are  also  more  orangey  and  they  tend  to  be  slimmer.  Females  are  slightly  less  colourful,  with  less  red  and  fewer  dark  squiggles  and  uncoloured  pelvic  fins.  They  have  rounder  bodies  and  a  slightly  paler  overall  colour.  Both  sexes  have  the  same  chunky  appearance  seen  in  Danio  choprai  and  the  hump-backed  of  Microrasbora  erythromicron.
 Breeding:  Pete  Liptrot  and  Paul  Dixon  of  the  Bolton  Museum  Aquarium  were  the  world's  first  fishkeepers  to  spawn  this  species,  and  they  managed  to  do  just  a  couple  of  weeks  after  the  fish  first  became  available  in  the  UK.  Very  little  is  known  about  reproduction.  Paul  says  that  he  observed  a  brightly-coloured  male  attempting  to  drive  females  into  a  spawning  mop  and  Pete  found  seven  small  eggs  in  a  clump  of  Java  moss  a  week  later  and  spotted  some  fry  which  had  already  hatched.  Said  Pete:  "The  eggs  have  been  laid  over  Java  Moss  and  appear  to  be  only  very  slightly  adhesive,  they  drop  out  of  the  moss  very  easily.  We've  removed  the  moss  to  another  aquarium  to  see  what  else  hatches.  As  we  were  moving  the  moss  one  of  the  smaller  males  was  very  busy  hunting  around  for  eggs  or  fry."
 Behaviour:  Males  can  be  rather  quarrelsome  with  each  other  and  often  flare,  spar  and  fight  resulting  in  minor  splits  to  the  fins.  Most  people  keeping  these  in  groups  of  six  plus  have  observed  shoaling  in  their  fish,  and  several  have  reported  minor  territoriality  in  males.
 Availability:  This  species  was  first  imported  into  Singapore  in  mid-September  and  arrived  in  the  UK  a  week  later.  Both  Wildwoods  and  BAS  currently  have  hundreds  in  stock  and  the  fish  has  also  appeared  on  import  lists  used  by  other  suppliers  around  the  country,  so  the  fish  should  be  more  widely  available  soon.  One  supplier  was  referring  to  the  fish  as  the  Fireworks  rasbora  and  cited  the  name  Rasbora  toei,  which  is  fictitious.  As  I  predicted  in  early  September  2006,  a  few  weeks  after  this  fish  was  discovered,  I  think  this  species  has  massive  commercial  potential  for  the  small  aquarium  market.  It  has  undoubtedly  been  the  most  talked  about  fish  species  of  2006,  and  the  century  so  far.
 Price:  Prices  vary,  but  currently  around  Â£6  each.  We  highly  advise  fishkeepers  to  avoid  this  species,  unless  they  are  capable  of  breeding  it.
 
 This  article  was  first  published  in  the  December  2006  issue  of  Practical  Fishkeeping.  The  stunning  photograph  is  the  work  of  Aaron  Koo.

 Hi  folks,
 
 This  species  has  been  given  the  new  common  name  "Celestial  Pearl  Danio".  Look  up  its  Wikipedia  entry  http://en.wikipedia.org/wiki/Celestichthys  and  you  will  see.
 
 The  "official"  Celestial  Pearl  Danio  Forum  at  www.celestialpearldanio.com  has  been  set  up.  Please  pay  us  a  visit  and  post  your  photos  of  this  amazing  fish  there!  Click  on  the  banner  below  to  go  there:

 Though  it's  an  old  thread,  I  thought  of  updating  the  below  info  in  the  same  thread  due  its  relevance
 
 Celestial  Pearl  danio  has  been  renamed  to  Danio  margaritatus

 Hi  All
 I  had  recently  seen  these  fish  at  Adip's  place  and  they  were  tank  bread  from  Singapore,  they  seem  to  be  doing  very  well  in  his  ADA  tank  as  well.
 Wild  caught  are  too  damn  sensitive  to  the  slightest  change  and  there  is  a  high  mortality.

 It  must  be  a  great  addition  to  any  fish  lover's  tank  or  shall  I  put  it  as  micro  fish  lovers  tank..some  one  like  me  who  fancies  the  smallest  of  fishes  and  get  bored  by  their  larger  comrades...
 
 But,  I  am  sure  this  will  cost  a  bomb  untill  we  keep  them  breeding  in  our  tanks  and  get  them  immuned  like  the  Neon  or  the  Cardinal  tetra...
 
 
 Would  request  Adip  topost  some  snaps  of  them.
 
 Cheers,

 If  I  remember  correctly,  Mitul  had  reported  that  somebody  on  IAH  who  had  taken  the  fish  from  him  had  manged  to  breed  them.

 Doesn't  look  like  a  very  difficult  fish  to  breed.  Just  isolate  the  ripe  females  and  good  males  to  a  breeding  tank.  
 
 These  being  so  small,  the  fry  should  be  fed  with  the  finest  of  fry  food  like  microworms  or  infusoria,  i  guess.

 Having  seen/handled  hundreds  of  wild  caught  specimens  (kept  a  few  dozen  as  well),  I  can  categorically  state  that  this  is  untrue.
