    I just saw this fish from TWS, the sales manager says it's a color-morph of the three-lined or Nannostomus trifasciatus. Looks interesting as I'm always looking for something different.

    Nannostomus digrammus4.jpg
    It is possible that this is a colour-morph, as the species Nannostomus trifasciatus is polymorphic, as indeed are most (if not all) of the species in this genus. The range of this one species extends over a vast area including the Guyanas and the western Amazon basin in Brazil, Peru, Colombia and Bolivia. The sister species N. beckfordi is known to have several colour morphs that are natural, depending upon the geographic region wherein the populations evolved, and N. marginatus (often confused with N. trifasciatus) was thought to have two morphs but they have now been described as distinct species, N. mortenthaleri and N. rubrocaudatus. This is quite a family of interesting aquarium fish.

    As far as I know, there are red splashes in the fins of N. trifasciatus, and this isn't clear in the photo. The photo is small (doesn't enlarge when clicked) so I can't see much with my old eyes, but I would suggest it might actually be N. digrammus, photo attached. I had a group of these a couple years ago, they arrived as a by-catch with some wild rummynose tetra.

    The great American ichthyologist Dr. Stanley Weitzman did his doctorate at Stanford on the pencilfish, and has to date contributed the most data to the literature. His reclassification (with Cobb) can be accessed here if interested:

    That is a cool looking little fish
    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    Thanks for the information and link Kermit. I thought they might be Nannostomus marylinae but the source sells them as a seperate species.

    This may be of interest. I was just checking in with the new ichthyological papers, and found one by Dr. Axel Zarske describing a new species of pencilfish closely related to N. trifasciatus. Dr. Zarske has named it Nannostomus nigrotaeniatus and there are some splendid colour photos of the fish in his paper, which is free here:
    http://www.senckenberg.de/files/cont...ke_preview.pdf

    The paper is in German, but the Abstract is in English (and French), and the photos can be enjoyed in any language.

    Nice find, Byron so many more species being found all the time. N. nigrotaeniatus looks more like fish in my original post.

    Off-topic, what do you know about the Bleeding blue tetra (Hyphessobrycon sp.)?

    Off-topic, what do you know about the Bleeding blue tetra (Hyphessobrycon sp.)?

    At first glance those look like Hyphessobrycon metae, sort of; photos online of H. metae are not always reliable, and they vary a lot. This species tends to have the faintest blue tips to the fins. I have had a small group of this species for five years now; they are not all that common.

    I did a Google on the common name and found a thread from last year in which you asked this, mentioning "Caracoides fargo." I know this is not valid, there is no genus Characoides according to the CAS database run by Dr. Eschmeyer and he is very reliable; no idea who may have made this up, but Characoid refers to characid of course. Hyphessobrycon sp. is probably "accurate," if this is a new species as yet undescribed. I think I mentioned in another thread about the new species being temporarily placed in this catch-all genus. The characteristics used by Durbin in 1908 (who is credited with naming the genus, which originally was a subgenus of Hemigrammus) were not all that distinctive, and Gery (1977) improved them a bit. But all that was prior to the knowledge of DNA which has changed everything.

    Peru is not surprising as the source. The three species H. metae, H. peruvianus and H. loretoensis all occur in relatively close proximity and are very similar, and frequently mixed up in photos even in books from 2-3 decades ago.

    There is Hyphessobrycon nigricinctus Zarske & Gery 2004, discussed and pictured here:
    http://www.tfhmagazine.com/details/a...ll-article.htm
    and this seems to be closely related again, if not the fish in question.

    Byron.

    I thought of Hyphessobrycon metae too, but most photo's don't quite match up like you said.

    I've suspected it to be Hyphessobrycon nigricinctus also.

    One things for sure, it's a very desirable fish. I'd ask you where you got your's but you being in Canada, it probably would not help me, LOL.

    Always nice to see more information on the rarer species, Thanks much.
