Since 2009 I have some specimens from the Puntius filamentosus group.
They were sold as P. filamentosus, but when they grew bigger I wasn't sure about the ID, mainly because of the faint (in males almost invisible) marking in the caudal fin.
I did read some papers and followed several discussions about the filamented barbs and recently I returned to the shop to find out the origin of my specimens.
The answer was: Wild caught and from Sri Lanka.

Did anybody see filamented barbs from Sri Lanka recently or in the past (I think Andy has seen them)

If they're really from Sri Lanka, I think they should be Puntius singhala

There's only one picture of P. singhala I could find on the internet.http://www.lakdasun.org/forum/.....opic=701.0
(and the ones in the paper ofcourse pdf)

Opinions will be appreciated.

If they're in the mood, the males can be quite red.

I had Srilankan Filaments a long time ago , and I'd guess off memory that yours could be ? mine like the ones in the pic lost the red and black caudal spots as they grew , and had a lot of nice green colours on the body , as small fish they had all the traits of the Indian fish i.e red and black caudal spots and some body markings too, soo could be ? Srilankan fish are pretty rare these days ?

Sorry for the late reply, but it took some time to get some decent pictures.

Yes, that's one of the reasons I wasn't sure if they're really from Sri Lanka.

But I've tried to observe my fishes again using the P. rohani paper and the P. filamentosus paper.

Head shot.
Maxillary barbels < 1/4 eye diameter (In P. rohani >1/4 eye diameter)
Snout length < eye diameter (In P.rohani and P. filamentosus snout length almost equal to eye diameter) Female

Male

I tried to count the lateral line scales, but I could use some help with it.

Dominant male - I think I count 20 (+1 or more on caudal fin base)

Same male, other site (black blotch starts at lateral line scale 14)

Better view on caudal peduncle

Male 2. This is the biggest male, but not the dominant one.
I think I count 21(+1 or more on caudal fin base) lateral line scales; black blotch starts on lateral line scale 15.

Lateral line scale counts from the two papers:
P. filamentosus:18, 19, 20 (+ 1-3 on caudal fin base)
P. rohani :21,22, 23 (+1 on caudal fin base)
P. singhala :20,21 (+1-3 on caudal fin base)

P. rohani should have 3 simple rays in the dorsal fin.
Male 3 (Smallest male)

Also the scale markings (see rohani paper image 4) seems to be different in my barbs.

So I think my fish could be P. singhala.
What do you think?

Think you're probably right having checked the papers Henri...

This has certainly given me food for thought! They look a LOT like the fish I have as "p. rohani"

will need to get pics to compare but they are a lot younger

Hi andy

yeah they became quite a roundish shaped barb but ended up getting my arm twisted until people had them all... yet to hear if anyone bred them?

I was looking at my "rohani" last night and one big difference is the tear drop which on my fish very clearly extends right into the caudal peduncle
