 Bhavania  australis  (Jerdon)
 
 Bhavania  australis  is  a  typical  hillstream  fish  occurring  only  in  the  small  streams  of  highly  elevated  areas.  The  present  study  covered  the  qualitative  and  quantitative  aspects  of  feeding  habit  of  this  fish  and  provides  an  indication  of  their  habitat.
 
 Results  and  discussion
 A  total  of  30  specimens  having  a  standard  length  ranging  between  5.5  to  8.7  cm  and  weight  3.8  to  5.4  gms.  were  collected  from  two  locations  of  Bharathapuzha  river  viz;  Walayar  and  Punchola  and  by  using  specialised  cast  net.  The  gut  content  analysis  of  Bhavania  auatralis  revealed  the  presence  of  the  following  food  items  which  are  classified  into  7  groups  (Fig  4.1)
 
 1.  Benthic  insects:  This  group  formed  15.50%  of  the  food  item.
 2.  Benthic  micro  invertebrates  like  cladocera  and  copepods:  constituted  8.50  %  of  the  consumed  food  materials.
 3.  Algal  matter  (benthic):  40%  of  the  food  was  algal  matter  attached  to  the  benthic  substrata.
 4.  Plant  matter:  Macro-vegetation  accounted  for  8.00%  of  the  food  consumed.  It  comprises  of  fragmentary/semi-digested  parts  of  leaves,  stem  and  roots  of  aquatic  plants  and  other  semi  digested  vegetable  matter.
 5.  Animal  matter:  2.35%  of  the  gut  content  comprised  of  unidentified  and  semi  digested  animal  matter.
 6.  Detritus:  5.00%  of  the  food  item  was  constituted  by  detritus.
 7.  Miscellaneous  matter:  included  all  other  items  in  the  gut  like  protozoans,  fish  eggs,  shell  matter,  crustacean  and  insect  appendages  and  sand  particles.  Here  sand  particles  formed  20.65%  of  the  gut  content.
 
 The  Index  of  preponderance  with  percentage  volunle  and  occurrence  of  the  different  food  item  is  given  in  Table  4.1.  The  highest  value  for  Index  of  preponderance  was  shown  by  Algal  matter  (  49.88  )  followed  by  sand  particles  (23.17)  and  the  lowest  value  was  for  animal  matter  (0.61).
 
 Observations  on  the  food  and  feeding  habits  of  Bhavania  australis  revealed  that  it  is  a  benthic  omnivore  which  mainly  feeds  on  benthic  insects,  insect  larvae,  copepods,  cladocerans  and  unicellular  and  filamentous  algae.
 
 There  was  no  marked  difference  in  the  intensity  of  feeding  between  males,  females  and  indeterminates.  65.00%  of  the  guts  examined  were  112  full  ,  22.50  %  114'~full  ,  9.00%  314"  full  and  3.50%  contained  only  trace  amounts.  None  of  the  guts  were  gorged,  full  or  empty.
 
 Table  4.1.  Percentage  volume,  occurrence  and  Index  of  Preponderance  of  different  food  items  of  Bhavania  australis  (Jerdon)
 
   
 
 
                 

 Algae  Matter  is  the  Winner...
 
 Regards

 Now  I  know  how  the  Wild  caught  Discus  keepers  feel.....
 
 Two  weeks  since  I  have  had  them  and  already  my  Pants  are  loose  and  I  have  dark  circles  and  bags  under  my  eyes,
 
 Balitora  mysorensis(ID'ied  by  Rahul,  Madhu  and  Beta).  But  I  would  still  like  to  Key  it!
 
 The  Day  it  was  caught.....
 Dated:  08-Jan-2012
 
 
 The  Biotope.
 Dated:  08-Jan-2011
 
 
 The  Fishchasers¬©  catching  them.
 dated:  08-Jan-2011
 
 
 Guys,  Correct  me  if  I  am  wrong,
 
 Substrate:  Large  Granite  rocks,  Smooth.  Minimum  size  around  Dia  6  inches.  Slime  covered.  Extremely  slippery.
 Water  Body:  River.
 Water  Flow:  Very  fast.  Enough  to  knock  you  off  your  feet.
 Depth  of  water:  Not  crossing  8  Inches.
 Water  Temperature:  Around  22-24  Degrees  Centigrade.
 Ambient  Temperature:  Around  27-28  Degrees  Centigrade.
 Time  caught:  3.00pm
 Numbers:  Found  in  Groups.  Around  50-60nos?
 Caught:  5  nos.  One  escaped.  Two  with  Rahul  and  two  with  me.
 Observation:  Would  go  into  cracks  or  under  the  Granite  when  disturbed,  only  to  return  a  short  time  later  to  the  same  exact  place  and  behave  as  if  nothing  happened.  If  one  was  caught,  another  would  take  that  place.  They  never  avoided  the  harsh  glare  of  the  afternoon  Sun.
 
 Regards,

 Doesn't  look  like  dimorphism  Nayak.   Looks  more  of  a  camouflage  &  it  definitely  looks  like  they  are  eating  your  artemia.   2  weeks  and  if  they  were  starving  you  can  literally  see  the  concave  belly  between  their  pectorals  &  pelvics.
