New Tetra?

[Byron Hosking]

I recently acquired a school of tetras that were named “red line tetra” in the store and by the exporter in Peru. I had thought they might be Hyphessobrycon amapaensis, but after three months in my planted 70g tank they have not coloured up as such; they were very washed out in the store tank. I have ben searching the internet, and did come across the attached photo that I am fairly certain is the fish I have. I found this photo on a German site, and the fish was described as a new un-named species of Hyphessobrycon. Has anyone seen this fish and know what it is?

I’m fairly sure it’s undescribed Kermit. I’m also sure I’ve seen it before but can’t put my finger on where…

wow, stunning, not seen those before.

I thought for a second I had found your fish today. On second look at your picture I’m not so sure, but thought I would post the link anyway!

This site has a LOT of fish profiles, may you can find it on there if this one isn’t it.

Thanks vintagetankgirl and Matt. Yes, VTG, I use FishBase quite a bit but this fish wasn’t there when I looked. The photo I posted was the only one I could find when I did a Google image search of “Hyphessobrycon” and viewed all the photos that came up (that took some time, I can tell you!). I also went through a listing of all H. species described in the last ten years (can’t remember where I found this, it turned up in one of my other searches) but as the vast majority have no photos and the descriptions are usually of internal things like the number of teeth or bones, it was impossible to know whether one of them might be this fish.

I have this question posed on the three forums I belong to but so far no one has identified it. Of course, it may very well be one of the now hundreds of new characins awaiting identification. The Peru Aquarium (exporter) site has a lengthy list of such species that have been found but not yet described by science. Reminds me of Sir David Attenborough’s comment in one of his Amazon programs that there are more than 3000 known species of fish within the Amazon system, more than in the entire Atlantic Ocean; and at the rate the rainforest is disappearing, hundreds of unknown species will become extinct without our ever knowing of their existence.

The mystery is solved. In a personal communication, Heiko Bleher has identified this fish as Hemigrammus coeruleus Durbin 1908, which he has collected in the lower Rio Negro through to Peru and believes it to have a wider distribution in the Amazon basin. I had also provided Heiko with photos of the fish in my aquarium (see attachments), and although they are lousy photos he is certain this is the fish. The darker fish in the photos I had thought were Hyphessobrycon peruvianus but Heiko says they are H. metae and I agree.

Beautiful, healthy-looking characins in your tank Byron and glad the mystery is finally solved. What else is in the tank? I see P. simulans, C. strigata, N. eques and H. loretoensis in those pics…

Thanks Matt. This is the 70g that has Carnegiella marthae marthae, C. myersi, C. strigata strigata and C. strigata fasciata, Nannobrycon eques, Poecilocharax weitzmani, Paracheirodon simulans, Hyphessobrycon loretoensis and H. metae, Hemigrammus coeruleus, Farlowella acus, Aspidoras pauciradiatus, Corydoras pygmaeus, C. duplicareus, C. similis and C. panda. I refer to this as the “quiet” group; the 90g is also SA but is just a bit more boisterous. There is a photo with a list of inhabitants in my folder (kermit58) in the gallery.

Cheers, Byron.
