I know the Black Fin Tiger Barb [P.tetrazona] was discassed on here a while back /thumbs_up.gif" style="vertical-align:middle" emoid=":thumbsup:" border="0" alt="thumbs_up.gif" /> I,m just a little confused though because there is a nice pic of said fish over on Aquarium Glasers site in the fish articles section , apparently Dieter Bork spawned them /thumbs_up.gif" style="vertical-align:middle" emoid=":thumbsup:" border="0" alt="thumbs_up.gif" />

What has confused me though is the fish on Aquarium Glasers site has the black completely covering the fins ,whereas the fish depicted in the book Freshwater Fishes Of Western Indonesia And Sulawesi has a white or clear edge on the dorsal and ventral fins , similar in style to P.anchisporus's red edge [ aquarium Tiger Barb ] can anyone enlighten me on this situation ?

Andy I assume you mean the two pics below? Looking closely I think the Glaser fish has very thin, pale distal bands on the dorsal and ventrals which could perhaps appear wider in a preserved specimen as in the Kottelat book?

The nomenclature situation is still unresolved as far as I know. /rolleyes.gif" style="vertical-align:middle" emoid=":rolleyes:" border="0" alt="rolleyes.gif" />

Also, for those interested, here's the original thread.

Hi Matt, if there is a distal band on the Glaser fish /wacko.gif" style="vertical-align:middle" emoid=":wacko:" border="0" alt="wacko.gif" /> then it is very thin /blink.gif" style="vertical-align:middle" emoid=":blink:" border="0" alt="blink.gif" />

Funnily enough there is a similar thread on the Practical Fish forum ,and Dieter Bork puts a photo of a live specimen up , but the distal band is quite distinct like Kottelats preserved specimen , I suppose the Glaser fish might be a youngster [it looks it ] it would be nice if Dieter Bork could enlighten us about this trait ,as he has bred them ! /thumbs_up.gif" style="vertical-align:middle" emoid=":thumbsup:" border="0" alt="thumbs_up.gif" />

I like the Glaser fish its a little beauty /wub.gif" style="vertical-align:middle" emoid=":wub:" border="0" alt="wub.gif" /> .

Hehe, yeah. I was referring to the very tips of the rays/membranes where some parts are showing paler. Just checked the thread you mention and the fish posted there does look different though!

Anyone know Dieter to ask him?

I think the picture on Glaser's website shows a displaying male (red nose, I remember reading a long time ago that tiger barbs can be sexed by the males developing a very red nose when "excited"), which might account for the greater amount of black on the fins. The black pigment may not be so prominent otherwise.

Wish I could get a few of those /wub.gif" style="vertical-align:middle" emoid=":wub:" border="0" alt="wub.gif" />

Think the Glaser fish might be P. pulcher as revalidated by Kottelat and Tan (2011)? It seems to fit the characters given quite well.

Edit: here follow the three species in the P. tetrazona group found in Borneo and Sumatra, then the aquarium fish.

P. anchisporus: complete lateral line, 14 circumpeduncular scales, 21-23+2 scales in the lateral row, dorsal-fin black with red outer band, pelvic fins red.

Distribution: Western Borneo.

Here are some wild P. anchisporus from Sarawak.

P. tetrazona: lateral line incomplete, 12 circumpeduncular scales, 19-21+2 scales in the lateral row, dorsal fin mostly black with paler outer margin, pelvic fins black in middle, hyaline at base and tip, vertical body stripes relatively wide (about 2.5 scales wide in middle of flank).

Distribution: Sumatra.

Need photos of live fish for this species. Edit, maybe this?

P. pulcher: lateral line incomplete, 12 circumpeduncular scales, 19-21+2 scales in the lateral row, dorsal fin entirely black, pelvic fins entirely black, vertical body stripes relatively thin (about 1.5 scales wide in middle of flank).

Distribution: eastern Borneo.

Wild specimens from East Kalimantan, plus the Glaser fish:

Aquarium tiger barbs show intermediate characters including: lateral line incomplete, dorsal-fin black with red outer band, pelvic fins red. I'm still confused.Confused
