I would call these an odd one.

Apparently not seen in the hobby but may be coming to Tropical Waters aquatics in Birmingham (their photo)

That's Trochilocharax ornatus.
Pretty new and rare in the hobby. I've seen them once at Zoo Zajac, a shop in Germany and were nice but very tiny characins.

I had these - quite delicate I found

kruseman · Post by **kruseman** » 22 Sep 2014, 20:40

Interesting.
In what way were these delicate? The food? Or waterparameters?

Hi kruseman,
This species is new to me but as a former fish shop owner, I look at the fish in the photo and one thought springs to mind. I bet those don't ship well.

They ate well enough and the males even displayed to the females for a while. Over time however they suffered from some kind of mouth rot and would go opaque and die off one at a time. I think I had them for about 6 months max.

Moved three males into a display tank couple of weeks ago, thought they'd be fairly shy and retiring but they're out at the front competing with the neons and bleeding blues, look great, the reflective spot on the abdomen is really glowing.

Picked up some "by catch" of Cheirodon simulans . Looks like 3 species. I need to pick up one Gnathocharax with black (!) pelvic fins when the hatched fish have recovered from their trip.

Not the rarest of tetras, but a school of tetras that I love watching. Their size doesn't really come across in the photo, but that is a 6 foot long 125 gallon (473 liter) tank for scale.

Alestes longipinnis ( or Brycinus?)

Very nice Nymphea btw.

Post by **Shane** » 13 Oct 2014, 21:26

Yes and several Congo tetras as well. The two big male longipinnis are a solid 4 inches (10 cm) SL.

These may not be the 'oddest' of characins - last night I was taking some pics of my mixed-species shoal of 40 rummy-noses and managed to capture pics of all 3 species in comparable poses. So here they are, Petitella georgiae, Hemigrammus rhodostomus and Hemigrammus bleheri:

Hope it's of interest to some ;)

I've always enjoyed rummy-nose tetras (I think P. georgiae is what we get around my town). I think their color patterns - the red nose and the black/white striped tail - make them look like old World War II allied fighter planes painted for D-Day:

That's a great comparison - thanks for sharing

I think of them as little torpedoes!
In the UK, commercially-bred Hemigrammus bleheri are very common in the hobby, the others are rarely seen and then only wild-caught.

Honestly, when we bought our rummy noses, we did not know which species was being sold. But you're right, I just Googled Hemigrammus bleheri and it looks just like what we bought. Are your three photos displayed in the same order as you typed your species names (Petitella georgiae, Hemigrammus rhodostomus and Hemigrammus bleheri)? Based on the prominence of the black/white tail stripes, your first photo looks most like what we used to own, and it most closely resembles the internet shows for H. bleheri when I Google it. But the tail in your third photo, which I presume should be H. bleheri based on order listed, doesn't resemble the tail of the rummy noses we've owned in the past. On the other hand, your first photo has a rather prominent black lateral strip extending anteriorly from the tail, and that was definitely not present on our fish and also I don't see it in the photos of H. bleheri from Google.

Mol_PMB · Post by **Mol_PMB** » 31 Oct 2014, 18:28

This is the reference I have been using, and I put my pics and species names in the same order as on this page so it's easy to compare.

http://feamane.org/pages/three_rummynose_2.html

The spots (1 or 2) on the caudal peduncle are clearer on the actual fish than they are in my photos.
The caudal fin patterns, the extent of red and the black lateral strip are all quite clear in the pics.

A lot of the online sources I have found use the 'wrong' image for the species being described.

Thanks. That website does a great job of itemizing the differences between the spp.

These are gorgeous once in spawning trim.

Marc, how was the temperament of your gnathocharax? I've got a shot at some but know absolutely nothing about them.

Also, are they jumpers? The long angled pectoral fins remind me of hatchetfish, aka 'aquatic rockets'

Alleykat asked me via PM , as the regulars will know, I think PMs are a poor way to share information as it is only a two way conversation and I don't really have the time for many of those (but always want to help where I can). So...

could you tell me what size yours are? I saw them once quite a while ago in a shop, and was immediately intrigued but didnt get any without some research. I read they can be quite aggressive, do they bother tankmates or mainly each other?

Mine are pretty uniformly 8cm SL. They are not aggressive however I keep ten of them with and neither of whom show any damage from their tank mates.

Hope that helps,

Jools

alleykat · Post by **alleykat** » 03 Feb 2015, 21:35

hi everybody!

sorry Jools.. the thought crossed my mind, but I was worried about 'contaminating' the mainly pictorial thread.Thank you for your quick reply, and I'll know what to do next time

They can and will jump (see pectorals indeed), peaceful despite visible teeth, surface orientated (see shape), easily fed, in one word a briljant little fish. One thing though: despite being with 15 specimens, they didn't shoal in my tank. If you don't object to individual behaviour, this one is highly recommended imo.

Nice to see someone else with these. Two of mine sometimes seem to take turns guarding a little cave, but I've never seen anything come of it. Have you managed to breed yours?

No, I haven't. And given the fact that my breedingattemps with characins almost always end in failure, chances are slim to none

Catxel · Post by **Catxel** » 24 Feb 2015, 06:36

I ordered some Slender Chameleon Tetras for the LFS I work at and they will be here friday in the fish shipment. I only found a cpl of articles on them and wondered if anyone here has had any personal experience with them? They seem pretty rare, but sound very cool. Of course, I will be taking a few home with me $\:d/$ Cant help customers if I haven't taken them on a test drive myself LOL. Anyone here ever have them?

Mol_PMB · Post by **Mol_PMB** » 24 Feb 2015, 10:12

Here's one of my less common tetra species: Phenacogrammus aurantiacus sp.lefini
This is an attractive tetra from the Congo. The photo also includes a 'normal' Congo tetra (Phenacogrammus interruptus) for comparison.

characinkid · Post by **characinkid** » 24 Feb 2015, 15:36

When you say they are Slender tetras, are these Iguanodectes? If so... cool fish..
