Right. How many have you got?

Nothing wrong with them. Do so!

Just that they are likely not T. galaxias unless they are being imported from either Venezuela or Colombia.

I have seen lots of Tatia imported as "galaxias" coming in from Peru but T. galaxias are not from here so the ID is questionable at best.

All Aucheniperids are particularly susceptable to "ich" and other parasitic skin infections. When you first get them, keep them warm (85F) for a couple weeks to help them settle in, this helps to prevent a possible outbreak should they be exposed/stressed in transit.

A have no idea where they are imported from, but I'll ask when I see them. If they are from Peru, what could they be if not T. galaxias? T. aulopygia?

daniel60 · Post by **daniel60** » 18 Oct 2006, 22:33

Tatia intermedia: Several hundreds of youngsters, the oldest ones four weeks old.
Tatia perugiae: Fry, but I didn't manage (or try hard enough) to keep them alive.
Trachelyopterichthys taeniatus: Witnessed copulation.
Tatia aulopygia, Auchenipterichthys coracoideus: Nothing - yet.
Don't really know why my T. intermedia keeps spawning. I don't do extra water changes in their tank, they don't get special food (just frozen artemia and blackworms, plus small NLS pellets). But a species tank seems to be a good idea.

Marc van Arc wrote:Right. How many have you got?

10. They don't seem as shy as the others, but I guess that can change...
I would really like the next Auchenipterid to be a little larger.

According to CoF, there are 3 Tatias native to Peru:
T. intermedia; T. perugiae & T. gyrina.
T. aulopygia is widely spread, but apparently not in Peru.

Paul,
I can't say I have the same experiences with regard to the above. I'd rather say they're very hardy, even when bought directly from the plane (at the wholesaler's; straight from the box without quarantine). However, this is of course not recommended.

Something completely different: these meal worms you spoke about; are those the ones that become flies??

pturley · Post by **pturley** » 19 Oct 2006, 00:21

No not flies, beetles. Tenobrio molitor

Correction: Tenebrio!

Jon · Post by **Jon** » 19 Oct 2006, 00:46

My experiences with tatia do coorespond to Paul's observations. They are indeed hardy fishes, but should ich be introduced into the system, all hell breaks loose.

Post by **Marc van Arc** » 19 Oct 2006, 11:45

Current stock mating attempts:
Liosomadoras oncinus: no (2 females)
Trachelyopterus fisheri: no
Trachelyopterus galeatus yes
Trachelyopterus sp. `guyana: no (2 males)
Auchenipterichthys coracoideus: no (too young)
Tatia perugiae: yes
Tatia intermedia: no (too young
Trachelyichthys exilis: no (ditto)

Fishes I used to have long ago:
Auchenipterichthys coracoideus: yes
Auchenipterichthys punctatus: yes
Pseudauchenipterus nodosus: yes
Liosomadoras oncinus: no
Tatia intermedia: yes
Tatia aulopygia: no
Ageneiosus magoi: yes
Trachelyichthys exilis: no
Trachelyopterus coriaceus: yes

Never(!) seen any eggs, let alone fry.... Perhaps because all these Auchenipterids were in the same tanks together?
And why eat flakes when there are freshly laid eggs on the menu?

Maybe because the eggs don't seem to taste very good?

Daniel,
I don't quite understand this remark. Could you explain pls?

daniel60 · Post by **daniel60** » 19 Oct 2006, 22:36

I'll try. The Tatia intermedia eggs had gelatinous covers, as you can see in a picture in a previous post. Maybe the covers makes the eggs less tasty.
The latest eggs in the tank was left untouched by the adult fish - 8 Tatia, 3 Scleromystax, 2 Pseudohemiodon - for more than two days. The eggs weren't hidden or protected by the female. Then the covers dissolved - and the fry disappeared.

Post by **Marc van Arc** » 20 Oct 2006, 10:50

Okay, I see. My thoughts were - taken into consideration that the parents would't eat their own eggs - species like Liosomadoras, Trachelyopterus and Ageneiosus wouldn't stop at other species' eggs. That would relatively be easy as Auchenipterids don't guard their eggs. It's just a matter of scavenging in the dark until one finds some unexpected protein.....
But it might as well be that there haven't been any eggs at all

Hi Marc,

Marc van Arc wrote:
Walter, I saw pictures of T. anduzei and it's definitely NOT your fish. Check this link http://www.auburn.edu/academic/science_ ... ndex1.html

checked the link ;)
I got a new video DVD some days ago - from German Andreas Stelzig, Michael BÃ¶ttner et al. : "Ventuari - Expedition zum FluÃ? der Rochen" (Ventuari - expedition to the river of stingrays): http://www.aqua-media.de/am_frames.html
They show (in a picture slide show of captured species) Trachelyopterichthys anduzei.
It doesn't look similar to the ones on the link you gave (maybe the pictures of Marc Sabaj show young specimen?). The T. anduzei in this movie more look like T. taeniatus, but more corpulent, plump...

Of course the Sabaj pictures are the more serious reference...

Hi,

I keep 5 or 6 Tatia perugiae and since yesterday 4 Trachelyopterichthys taeniatus, from Walter.
Some pictures:

sidguppy · Post by **sidguppy** » 05 Nov 2006, 11:55

interesting fish and rare. fully mature? what's the length of your fish?

"Germany" is a big place. can you tell us where you got these cats? LFS lokation?

not that I'm getting Auchenipterids (I'll leave those to Marc and other enthousiasts), but an importer or LFS that carries rarities like these is likely to carry other unusual fish as well......

Oliver D. · Post by **Oliver D.** » 05 Nov 2006, 12:12

Hi Sid,

fully mature?

I think...

what's the length of your fish?

Between 15 and 17 cm. Currently measured for you!

"Germany" is a big place. can you tell us where you got these cats? LFS lokation?

I must refresh my profil. I live since some years in Austria - sorry...

They come from http://www.transfish.de , near Munich.

Regards,
Oliver

Just checked; alas, you must be a shopkeeper or someone with a very good connection.
those people don't sell to customers; only to shopkeepers/salespersons.

ah well, I tried

Oliver D. · Post by **Oliver D.** » 05 Nov 2006, 16:20

Yes - you need a trade certificate, or must study/work on a university, as Walter.
ItÂ´s a wholesaler.

Centrmochlus perugiae, Tatia galaxias, My experiences with both species are easy to keep, easy to breed. Both species bred on a monthly basis, water conditions unimportant,best foods that promote breeding 1)frozen bloodworms 2) frozen glassworms ( sometimes labeled as white mosquito larvae)
Have actually watched galaxias female oozing eggs from her vent during the day in a spot between 2 large Anubias leaves. The galaxias deposit their gelatinous covered eggs in an inconspicuous site and leave them alone. The perugiae females find a snug hole or crook in a piece of driftwood( the size of the plastic 35mm. film containers )and care for the eggs until they are free-swimming. Fry were easy to raise using bbs. and were not hard to get to accept any other foods. Would love to try Jaguars if I could find some.

So what are you going to do with your Auchenipterids?

grokefish · Post by **grokefish** » 28 Nov 2006, 04:34

Eat them!
No, I've been on this metal island for too long.
But I really am considering keeping only loricariidae, cause they come out all the time.
Hey marc my Uarus bred again so I moved them to another tank and the baby fish are doing great, i havn't seen them yet but Kat has told me they are getting quite big now.
Also when i moved them, almost imediately another pair laid eggs in the original tank!
Oh no I'm gonna have millions of Uarus now!

Hey Grokefish,
You can subtract my 20 Tatia perugiae off the list. They all caught the plague some new plecos brought in and every last one died of it. The disease has finally burnt itself out but at a cost of about $1000 worth of catfish by the time it was over with.

Wow. That's a bummer

. Are you going to keep them again or will you leave it at this?
Btw: there must have been more fish involved when I look at the amount of money. Those new plecos as well?

Are you in a hurry with getting rid of the Auchenipterids? If not we might figure something out.

Yes Grokefish, it killed many expensive Hypancistrus, Pecoltia, all my oil cats and even some female Halfmoon Bettas. It was the single largest disaster in my 40 years of fish keeping. I won't try to replace the oil cats but I do have seven new L134 coming in tomorrow so I'll have eight.
This was one of those diseases that ran through my collection like Ebola through an African village. Chilodonella was the only organism I could positively idendify under the microscope but that was probably secondary to what the real killer was. I wish I could keep chloramphenicol on hand but it is no longer available in the USA in water soluble capsule form as it is a dangerous drug, killing 1/40,000 from irreversble aplastic anemia. I used to have good success with similar diseases in the early seventies when I was bringing in box lots of fish from SA. The laws have changed and now the available drugs are not very effective because of the resistance that various bacteria have built up over the years.
After tomorrow's two shipments come in and if all goes well , I won't be bring in very many fish because I will have built up sufficient numbers of the various Corydoras and plecos I want to work with. I still want some Apistogramma hansbaenschi and Hypancistrus zebra but I can get those from friends who are breeding them.
It is hard to practice perfect lab practice and effective quarantine in a small fish room when you are shipping in a lot of fish from varied sources frequently. Sooner or later crosscontamination is inevitable.
I will be in the position of shipping out far more than shipping in now. Hopefully I'll start ejoying my hobby more. I have come close to quitting as I went through this plague upon my house.

Larry,
It remains a sad story. Hope you won't be visited by disasters like that again and regain some joy from the hobby.
Fwiw: I'm not Grokefish.
