Do you know much about Nannostamus anduzei

Yes. See post #6 in this thread. Tiny jewels.

I read your post but it didn't talk about their bheavior; are they aggressive like trifs, do they group up like marylin, ....

I did:

"And the males are FIERCE. Aggression is confined solely among males. I had a colony of 40 and would periodically fish out a corpse or two and they were always males."

Males establish mini-territories.

I read your post too fast; that is sad. I was thinking of getting 10 for a 65 but this tank doesn't want aggressive critters.

From serouslyfish this is interesting:
--
PH in the stream was 5.0 and water temperature 27°C/80.6°F in December 1984, while in the lagoon pH varied between 5.0-7.0, water temperature was around 30°C/86°F. N. anduzei was only collected from slowly-moving water among the plants in the stream and parts of the lagoon under its influence.

It was not collected from any acidic black waters which comprise most of the surrounding aquatic habitats.

The rio Ererê fish were collected from a black water biotope, however, and the males possessed longer anal fins than the Venezuelan population.

Gee they have a mile long write up of the fish - oh well probably not suitable for what i had in mind...

They are so tiny and slender, maxing out at barely 1/2", I fear they would get lost in a 65g, though that certainly would offer the males some elbow room. The color is intense, particularly the depth of the red on the males.

If they ever wander my way, I'd say those sound like fish that would never suit my purposes, but where I'd set up to suit theirs. Some fish are just too interesting to combine with other species.

I might try 6 or 8 in a 15; they aren't cheap but i really wanted something closer to marylinae in behavior that schooled and stay in upper region - not something like trif that create territories and aggressively defend them. In fact i didn't even want something like marg who scatter everywhere.

 

[Innesfan52 15]

In my set-ups, the females shoal above and the males do their almost comical territorial thing below. I kept them in 20g and 29g. Species tanks in both instances. For a brief period there were cories, H. atropersonatus, in one of the tanks that made no difference in the Anduzei behavior. But I removed them to improve the chances of Anduzei eggs and fry surviving. I must say that despite their truly diminutive size--remember, they are among the ten smallest of all vertebrates-- they drew a lot of attention from visitors. There's something about that much intensity of color packed into so small a package that catches your attention.

Here are some tattered pages from the TFH article about them that Stan Weitzman wrote after describing the species. The red ink notations are in his hand--his corrections of TFH editorial errors--that he made before sending me the article. SeriouslyFish got much of their info from this piece and Stan's initial paper describing the species.

If i buy some for a 15 it would be a tank i use to attempt to breed some fishes i've had a while that haven't been able to breed in their larger shared tank. Specifically first the a. ladisalo (which i think paired a while ago) and later the D39. So it wouldn't be the best place for them but there would be nothing else in the aquarium.
--
I think i'm going to skip them. I just don't have an acceptable setup for them and i want to try to focus on the ladisalo before they age out.
--
I think i'll get 30 ruby tetra instead (not for the 15); in truth they are really pretty and they don't fight !

Somehow when I visualize @Innesfan 's fish set up, in my mind it morphs into lots of shiny metal framed tanks.

This is a great fish discussion where I sit like a fly on the wall and learn. I've spent years getting excited about subtle location/population differences in killies - I think that's a reason why I love those fish. To see the same kind of information exists about Nannostomus, a group I've long admired but usually from afar is really wonderful.

When I see we've had 100,000 forum members, I realize that keeping fish the wrong way is boring, and people leave the hobby. Just looking at them has its limits. Observing them closely and learning their natural history changes the game. The goal is to find a fish that looks to you like @Innesfan looks at Nannostomus!

There's something about that level of attention — noticing the small things, tracking differences most people ignore — that carries over into other hobbies too. I've been spending some downtime on Fast Payout Casinos site lately, and oddly enough, it's the same kind of patience that helps there. You slow down, pay attention, and stop expecting everything to be flashy and obvious.

Totally agree, there’s something magical about diving deep into the natural history and subtle differences of fish populations.

So i picked up a small group of these - can't say anything about species or sex:

There is one little tucano in there.

I'm thinking they are some odd colour triff the part that is bothering me is the extra red line running next tot he middle black line. - also the lack of violence seen with triffs.
