What does this inlet look like?

Like a comb.

But could a fish actually get stuck on it or even pulled through it? And if the latter, what happens next?

I know exactly how this feels.
Ageneiosus are terrible good in making it´s keepers getting panic.

No, the mesh is too narrow for an Ageneiosus to be pulled through. But the fish was laying on its side against it. When I tried to get it away from there it looked like it couldn't because of the current.
I think it even damaged the fish a bit.

You're absolutely right, Acanthicus. Some scary stuff.

Well, it's a good thing the both of you haven't kept Tetranematichthys.....

Give it some time Arjan, and if it doesn't work for you we'll figure something out. I do hope it does work out, let me make that clear.

I will, Marc.
I fixed the thingy with the mesh and heightened it as well so no fish can jump over it in the future.

The Ageneiosus are swimming in the current right now. I haven't actually spotted them feeding yet. Ituglanis and Tatia intermedia are gluttons. How is that with your tank? Do the delphins have the oppotunity to find food?

anyone still stating that this Ageneiosus species still doesn't show sex differences?

the second pic is quite clear!

left and upper right fish are females; the one in the middle is a male....

enlarge the pic and check those anal fins!

Rats.

Yes . No, of course not .
But that gives Arjan 2 extra tasks: can you measure them, for now I would really like to know their size so I can add this info to the data sheet.
Plus: can you have a look if there are more males in your group?

@ Arjan: my 2 specimens in the small tank have no food competitors (so no problems) and the 2 in the large tank were even capable of getting food when the tank still included my larger woodcats + Triportheus + Markiana. I wouldn't worry a bit!

I also think that the picture showing 3 is definitely worthy of the Catelog.....

Just picked these up yesterday. Only small - max 5cm TL.

Here they are a bit bigger. They are VERY greedy:

And what do you think they are? Does the stripe on the back make them T. insignis?

I'm not sure yet Marc. They are only smallish. I don't think they are insignis though. The true insignis is more like a fisheri type. Time may tell.

On the subject of updates. This sp from Peru:

Has now turned into this (still changing):

I measered a lager male : 65 mm

Marc van Arc wrote:Plus: can you have a look if there are more males in your group?

I tried, but it's pretty hard. They don't like to be looked at by a flashlight. I need some more time here.

Well, that's reassuring. I hope they will get a little bolder when feeding. Tomorrow the first babyguppies will be added to the tank.

I really like these fish.

I am loving this thread, but after 80 plus pages it is getting hard to use as a reference (and there is a lot of good information). Can we start splitting it when a new species is brought up?
-Shane

maybe a split is in oder; we might want to start a threat like "All things Ageneiosus", "Tatia's and other small Auchenipterids", "Aucxhenipterid taxonomy topic", "keeping Driftwood cats" etc

then you have your split, but it's clear where people want to search

someone wanting to know anything about Centromochlus perugiae knows it's in the "tatia et al" topic, while the people interested into new unnamed species can do their picture and scientific paper things elsewhere

etc etc

;)

just a little idea, mind

I like Sid's idea, but there is also some momentum to leave it as one big thread. It is really up to those contributing to it. I was just thinking about making the information more accesible. Last thinng I want to do is take the energy out of this discussion.
-Shane

It is getting very long but I think it is OK as it is. The search facility still allows things to be picked up.

I have kept, but no longer have, Auchenipterichthys coracoideus & Trachelyichthys exilis.

that is an awesome video. so natural! Great setup for these guys!

That video just shows why other catfish species should be more common when compared to say iridescent sharks, Pangasius hypophthalmus.

Jeremy

Yeah. But the latter is much cheaper and easier to obtain. One shouldn't keep them though, that's for sure. Not an aquariumfish at all.

After a week or so being pretty nervous about the atronasus' eating enough I've noticed that they do.
They like frozen artemia and white mosq.larvae in particular.
I was and still am a little concerned about other tankinhabitants like Tatia intermedia and Parodon affinis being glutons and gobbling up al the food that drifts in the current before the dolphins can get it.
It's not the cheekyist catfish around. They don't seem to be bottomfeeders.

T. fisheri

cool!

I thought "here's just another piece of wood(cat)", but it looks like the female fisheri has lost some of the shyness

I'm not keeping any Auchenipterids yet and I'm completely new with them, and very interested.

I was wondering wich of the smaller Auchenipterids ( max 15cm ) are ( relative) active during the day ?

it's sort of THE hallmark of this specific family that they are noctural and extremely shy

the few exceptions that swim about in daylight are the hard ones to keep; we're talking some larger Ageneiosus, Auchenipterus spp and perhaps Centromochlus heckeli

none of those is easy to keep, some are very very hard to keep.

if you want a day active catfish, Auchenipteridae isn't the family to find em

the ones I mentioned above are a challenge even for very experienced catfish keepers.

Anyone knows if Ageneiosus have been breed?
Should be very interesting to see whats the spawning behaviour like.
