Pangio sp. ?
 

seeing we're having so much fun with loaches, here's a couple more…

a dark brown slim one from LFS.

Pangio oblonga

I thought "Pangio oblonga" the moment I saw the photo. No doubt in my mind this is Pangio oblonga, also commonly known in many pet shops as "Black Khuli Loach" or Chocolate Khuli Loach. Interestingly enough, I have found that this particular species of Pangio is more active during the day than Pangio khuli, an interesting comparioson. It is a bulky species in comparison to Pangio shelfordi some other, less frequently seen species of Pangio.

Keep the loach pics coming! Great stuff!

is it! I thought P. oblonga has a thick body like P. myersi? I got this guy in a tank of kuhli's like this one, together with that other patternless kuhli discussed here.

P. kuhli




here's what I think is P. myersi, you can compare the sand grains to gauge the size of the fish.

P. myersi

having said what I just said, I checked the Kottelat Lao book and it says: "plain brown body, no nasal barbel, relatively slender body depth 7-8 times in SL, caudal emarginate."

so does my fish lack a nasal barbel and what is emarginate?

If I'm not wrong, emarginate= rather concave (at margin of fin's tip)??!! :drunk:

looks like body depth is reasonably close at almost 6.8 times into SL, measuring from the dorsal spine base vertically down to the abdomen.

Emarginate means the fin is concave in the center (think of it as being very gently forked, or somewhere between truncate and forked).

OK, so my fish has emarginate caudal fin. :) what about that nasal barbel?

I see a skin flap, but no nasal barbel.

ah good. have to see whether Kottelat describes this nasal barbel anot :)

Pangio from China
 

Recently Aq.Glaser received some Pangio sp. from a shipment from China. I don't think that they were caught in China, my guess is they are from some southern surrounding countries. I searched former threads concerning Pangio and found one with a close affinity which was believed to be P. oblonga. What do you think, is the blue headed loach on my pics the same species?



The other two species where containments, one might be P. anguillaris, and the other one I have no idea (P. sp. Brownstripe).

The long, thing Pangio is P. doriae, and the last one is P. shelfordii, I think.

I'm still confused over P. doriae and P. anguillaris. How do we differentiate them easily?

Pangio doriae has nasal barbels. Pangio anguillaris doesn't.
