ID: Hemigrammus sp.?

[CK Yeo]

Any idea what are these? I thought they look like juvenile short body Hemigrammus ocellifer, but not quite. I am not sure. Short body fish are all over the island now.
Any ideas?



Adult Hemigrammus ocellifer for comparison.

Hemigrammus pulcher. Body looks to be okay proportionately. Maybe not as deep bodied as H. ocellifer?

That's it! Thanks!
Will keep them for a while to see what they grow up to...

Hi guys,

this is Heiko Bleher www.aquapress-bleher.com and just a fast note:

This is also H. ocellifer. I just come back from 3 more Amazon expeditions and again I found ocellifer in the Rio Negro syste, in the extreme western Amazon area, the Calderon creek (border with Colombia) and in the upper Jutaí, a right hand affluent of the Rio Solimoes (Amazon). You can see the first part of my 3 destination on my website under expeditions Prestent.

I am writing this so you know that the species is only found in black waters and everywhere I collected them they have a slightly different color pattern. Same as with many other fish species, once the been geographically separated by whatever means, they change some pattern (and maybe in 100,000 years becaus a new species...). But for the time being, what you have is also cocellifer.

All the very best,

always

Hey Heiko!
We heard about the fiasco that happened to you in Brazil.
Hope all is well now and you're back in action!

Hi,
thanks almost all ok now, except for our stuff which is still all there...

Have a look at:
www.aquapress-bleher.com

But in any event it was 3 fantastic unexplored regions (as I always do), whith extreme exciting results. Hopefully soon coming up.


Thanks again and all the best

Interesting information there, Heiko.

The pictures of H. pulcher on the Internet are almost indistinguishable from CK's pictures. Could you kindly enlighten us on how to tell these H. ocellifer variants from H. pulcher apart?

Thanks in advance.

Hi,
just very fast as I am about to give 4 lectures and interviews in Duisburg, Germany, for the 11th Zierfische & Aquarium and the 7th International Discus Championships:

1. There are 3 very similar species described:

H. haraldi with a very weak elongated humeral spot and very large eye; lower caudal peduncle black upper golden/yelloish;
H. ocellifer with a almost round strong humeral spot flanked (before and after it) by a silver/golden spot; in the caudal peduncle a larger black spot and before it a luminating golden/yellow spot;
H. pulcher with a very large (largest and strongest of the 3) humeral spot which is elongated (pointed) down to its belly like an arrow; and sometime in vivo a second humeral spot is visible (it may look like two paralell going vertical down); the black in the caudal peduncle starts already very broad shortly after the end of the dorsal below the lateral line and extends into the begin of the tail with a (not so strong as in the other two) yellowish spot below the adipose fin.

I hope it helps.

Note also that H. haraldi was originally described as H. pulcher haraldi, as a subspecies.

All the very best

Heiko

Hi Heiko,

The fish in my picture seems to match your description for H. pulcher.
Perhaps you read my post too fast. Here the picture for you again.
