Hi,
Was trying to do some reading up on the species profiles on CotM but realised a lot of the links don't work for me. For example, my search on the entry on Corydoras atropersonatus (Apr 1998), led to this message:

Parse error: syntax error, unexpected '=' in /home/.heathcote/webcat ...

I think what Yann and Heok Hee meant is when you use cf. and aff. , there's no need for a "sp." in front.

So "Corydoras sp. cf. burgessi "should just be "Corydoras cf. burgessi"

Cheers

Congrats Ian!

I would think yes, to a species whose markings could display great variability.

Jools, the one in the catalog is a different fish from the one I posted in the thread highlighted by Yann. Both Nannoptopoma sp. can be found in the same thread.

The one Waldo posted has stripes on the head which runs parallel to the body. The one you posted as Otocinclus. 2 is clear of markings ...

the more common "romanised" form is "fumassa" actually and yes, C. areio is it's tradename in the Japanese Corydoras community.

I discovered that they are excellent mid-water swimmers and often school around, always foraging amongst leaves of plants for food. Mine readily take dry food so feeding shouldn't be much of a problem.

I've not bred them so I can't say much. I myself am trying to breed my brood of 12 to spawn ...

your tank condition seems ideal for them. with good feeding and stabilisation, they should show the iridescent reticulated marking on the body for the males.

You can easily roll them off the tank glass with your index finger as Corydoras eggs have an adhesive coating which allows them to stick themselves onto the tank glass or silicone sealant in the first place.

Good luck!!!

Having kept another Peruvian Nannoptopoma sp. before, I'm inclined to think that they are a Nannoptopoma sp. rather than an Otocinclus sp.

Here's a picture of the other Nannoptopoma sp.

PS: the snout is really depressed as ...

Would it be possible to get a close-up picture of the lateral line pores, and of the plates on the belly?

I'm thinking this might be an (undescribed) Otocinclus .


Hi Mike,
I'll see what I can do about the underbelly shots. Would need them to scale the tank glass for me to get a good shot ...

no no no... they were seperately imported. The Nannoptopoma were imported about a month back whilst P. maculicauda came in only 2 weeks back. From two different suppliers in Taiwan. I happen to quarantine them together in the same tank. Sorry for the confusion.

Saw a picture of this from a Peru exporter, Stingray Aquarium's advertising brochure about a month ago during Aquarama 2005.

Managed to get 4 specimens from Taiwan last week. Here's one of them with a Parotocinclus maculicauda ...

But the picture of the specimen from your website doesn't look like a long-nosed species. :?:

By the way, are those specimens in the following picture the true C. steindachneri from Brazil? Or also C7 from Peru?

Hi Ian,
I have absolutely no idea where these guys come from cos they are not mine, but taken from a Taiwanese website. First look I thought they are C. aurofrenatus. Would that be a possiblity?


Alan

Came across these pictures and they were labelled "Corydoras sp."

Does anyone have any idea what they are?

I think there is a conflict with what you want. Most pl*co favour places where they can hid out of sigh without being seen. You'll have to weight what you want more. To be able to see the pl*co all the times or for the pl*co to be confortable. You can't have both.


I think that is what Star-flog ...

For a 5-ft tank, you might want to try out the latest Eheim Pro III 2080 which was just launched very recently in Singapore. It has two outlets, as well as an inlet with a T-joint leading to two tubes which you can position at desired places in the tank. Basically, the design of the filter allows ...

hi Dave,
What gorgeous specimens! Absolutely beautiful! You intend to breed them?


Cheers,

Alan

Hi Ian,
from your experience, what's the most effective way to treat Gill flukes and Camalanus worms ?


Thanks so much

Alan

Got this fella from a shipment that came as Corydoras sp. "high fin", which is a pointed snout species. She resembles Corydoras brevirostris greatly but lacking in the heavy punctation one would observe on C. brevirostris . Though there is banding on her caudal fin, it is rather faint, not what one ...

As I've replied you on Petfrd, I don't think it is C.simulatus.

You might also wish to know that the cories labelled "C. agassizi"in your site are actually Corydoras sodalis.

They look more like C131 Corydoras sp. aff. leopardus to me.

Here's a reference for you:

Pruzsinszky, I. & F. Ladich (1998). Sound production and reproductive behaviour of the armored catfish Corydoras paleatus (Callichthyidae). Environ. Biol. Fishes, 53, 183 - 191.

Coryman wrote:I would say that mostly it will be males that display elongated dorsal rays, but it is also possible for females of some species to display extended rays although not so pronounced as the males.

Ian

Like Corydoras robustus?

The question that came to mind when I saw the pictures is "Are all the high-finned specimens featured really from Purus, Brazil? Or is it because they have high fins and then they were labelled to be from Purus?" In any case, they are fantastic-looking specimens! :)

Finnage extension amongst well ...

I'm a bit concerned about the barbs in your tank. Are they nippy??

Very beautiful C. polystictus you have there.

Hmm... Ian, that's an interesting observation.

It does seem to fit Nijssen's original description for being "closely related to the sympatric C. trilineatus but lacking in the zig-zag line at the junctiure of the dorsolateral and ventrolateral scutes. "
