Really curious to know what this is.
|
Looks like B. carnaticus only. I can see a solid dorsal spine and large scales.

In case it helps to Id the molested Labeo, Labeo calbasu,L.dero,L.pangusia and L.rohita have been reported from this area.
|
Not L. calbasu or L. rohita. Could be the either of the other two, but I thought both were kinda North Indian fish. They could have been introduced as a food fish also. 
I speculated the Labeo as L. kontius because it fit the description and is an indigenous carp of the cauvery and sometimes makes up 50% of the catch (Talwar & Jhingran 1991) |

Is it possible the fish in the last pic could be O.longidarsalis ? its the commet markings in the caudal that got me wondering ? I dont know if you kept the fish ,but if so perhaps a clearer pic of the head might help ?
Nice pic of the O.brevidorsalis ,first time I've ever seen one  must admit Nashii was my first thought ,though I did feel it looked a bit deeper in the body ? |

Hi Andy,
I feel it is Cirrhinus reba only...
Reason:
1) approx 35 or 36 lateral line scales
2) I can see a rostral barbel in one of the pics
3) Lateral transeverse 7/1/6
4) Snout projecting beyond mouth
5) Dorsal fin with 8 branched rays (have given the pic below....seven are clearly seen one more could be there) O. longidorsalis has 10 branched rays
6) Hexagonal shaped scales
7) Anal/ pelvics orangish
Photo credits: Prasoon Nair
Moreover I feel O. longidorsalis is found in a west flowing drainage Chalakudy while Hogenakkal is on Cauvery an east flowing drainage. I feel there is more probability of the fish being C. reba than O. longidorsalis as C. reba is abundant in Cauvery (Talwar & Jhingran 1991) |

Hi Marc , I bow to your much superior scientific knowledge  I,m agraid all my diagnosis is strictly made with the eyes  the only thing that does confuse me though is the plainish body , as I'd assumed Cirrhinus reba had those lines running laterally down the body ,plus for me it looked quite different to the Reba's in the other pics  I did have a Longidosalis sent to me by Andrew Rao [it was a beautiful fish ] sadly it completely dissapeared after only a few days , it just vanished out of thin air  never found its body ? there was a great pic on petfrd of my fish ,but the site got hacked hence all the material got lost !
Is it impossible that a few specimens [Longidorsalis ] could have got lost and ended up in the east flowing river  are the fish from the collestion still alive ? perhaps a tank shot of the Cirrhina and the Cirrhina ? could help 
Yours Andy . |

Hey Andy, I guess there is a mix up again.........are you refering to the fish in the plastic bag? If so I believe that is a B. carnaticus.....

My knowledge is very limited....I have experience only in Cyprininae (barbs & carps) and to a small extent in Rasborinae (barils, danios & rasbora etc.)....I admire your experience and knowledge on Indian barbs though you stayin' far from India

Am notoriously known as the fish torturer cause I preserve most of the fish collected, as I dont have many holding tanks and all my big tanks are dedicated to the P. filamentosus complex. I had a few of the specimens collected alive till a few days back. Now I have them preserved, will post the pics when I manage good photos |

Hi Marc nothing to beat a good mix up
Carnaticus are good looking fish looking at the S.subnastus to say its in the Sarana group it looks very different
What threw me was the fish hiding behind the Brevidorsalis I assumed it was Carnaticus is it a Neolissochilus sp/ ?
Marc ,you really should get some more tank space

Hi Andy
I guess it is not a Neolissochilus, cause Neolissochilus of south India do not have an osseous dorsal spine. The fish in question has a clear tough dorsal spine a diagnostic character of Barbodes carnaticus.

I really do hope to expand my holding capacity of live fish |

The fish behind O. brevidorsalis has clear barbels which are not so in the case of O. longidorsalis.
To put our doubts to rest I compare both the fish........
The fish brought by Balaji......most probably the one in the bag (last pic) side by side with O. longidorsalis (Thanks to Beta for giving me many a rare species )
Close up of the tail of B. carnaticus....note the dark principle rays
Close up of the tail of O. longidorsalis.....note the dark principle rays
Close up of mouth of B. carnaticus note the prominant barbel
Close up of mouth of O. longidorsalis
To close a few live snaps of O. longidorsalis provided by a good friend
The main stricking difference is the higher number of lateral line scales in O. longidorsalis (~ 39) while the fish in the cover may max have around ~28 or 29. O. longidorsalis is a more sleeker fish while B. carnaticus is a deeper one. B. carnaticus has a tough dorsal spine clearly visible in the fish in the cover, O. longidorsalis does not have a tough spine.
Its upto you guys to choose on the id. I stand by Barbodes carnaticus |

Hi Marc , I'm not doubting you that Longidorsalis in the pic by Andy Taylor is the one sent over for me by Andrew Rao Andy Taylor took the pics before I picked the fish up doesn't the internet make the world a small place Andrew had about four longidorsalis for me ,but the one in the pic was thee only one that survived ,that is until it dissapeared on me 
Marc thanks for the input this is an interesting thread SO we can rule out Longidorsalis .
The fish in the photo tank behind the O.brevidorsalis and the fish in the bag [last pic ] are the same ,both are B.carnaticus .
The P.sarana subnastus ? any thoughts on this ?
Again thanks for taking the time to explain and for your patience
Yours Andy . |
