Re: Corydoras julii or hybrid ?

Hi,

I don't see anything that would suspect me of this being a hybrid. However, it is most likely C. trilineatus which is commonly sold as C. julii.
The albinos are most likely C. schultzei / C. aeneus, a sharper picture especially of the dorsal fin could confirm this.

Cheers,

Re: Corydoras bilineatus

Hi, Corydoras sp. "San Juan" is to my knowledge only a trade name (like deckeri cory in Colombia) not used for only one species or form but a mix. No one in Iquitos will keep those separated acc. to locations and when those are stressed or juveniles they look probably anyway same. This is ...

Re: Corydoras bilineatus

Hi Daniel,

I can remember that many years back there were in GB some alleged Corydoras bilineatus which might have been descendants of the stock of Joachim Knaack but I don't remember if this was confirmed or not.
If so, I assume Ian or Hans-Georg might know more...

Corydoras bilineatus

Hi, I'm quite sure than some if not all picture in the data base are not really Corydoras bilineatus . They are all additionally labeled as "San Juan" cory which is the trade name for Elegans group corys in Iquitos, Peru. I think it's named after the district San Juan Bautista south-west o...

Re: A couple more IDs - C. leopardus & C. bilineatus

Hi,

Corydoras bilineatus is a species that you would not expect to find in the pet trade, so I would exclude this species, there are many forms that are much more likely...
I fully agree that this is a really a tough group for ID'ing, I'm leaning towards CW029 without being sure though...

C. coppenamensis

Hi,

this first picture from Roland is CW137 (Corantijne drainage), the second one is a true C. coppenamensis.

Re: I love them so! Please help me identify them.

Hi,
bekateen wrote: Thu Oct 29, 2020 9:11 pm Yes, but more likely the leopardus relative Corydoras(ln8sc4) sp(c102). The black markings are thicker and farther apart on C102 than on Corydoras(ln8sc4) leopardus once they are fully grown.
I fully agree on this.

Re: Corydoras IDx2

Hi,

I would tentatively also say C. napoensis and C. elegans.
CW008 looks also similar but to my experience this is unlike many other species in the elegans group quite uniform in colouration and has a more regular striped pattern.

C. nanus can be excluded by minimum 100% ;-).

Re: Corydoras aeneus?

Hi, it's definitely not C. aeneus in sensu stricto and I would not even call it C. aeneus at all but C. melanotaenia even though the fins are not so bright yellow to exclude all doubts... There are so many C. aeneus look-a-likes in South America. One thing is clear, it's a really nice shot of a nice...

Re: ID Elegans group cories

Hi, you will never find C. nanus (Suriname) or C. bilineatus (Bolivia) in ordinary pet shops, if you ever should be so lucky to find them in specialised shops they should be very much more expensive than other Corydoras . Both species are coming from countries from which there are no regular exports...

Re: Need help identifying my catfish

Hi Eric,

perhaps you were refering to this one: CW132 ?

But I also think that B. splendens is more probable.
