Corydoras Species "groups"

[Kuhni]

Hey all,

Would love to have a discussion on the boundaries of the so called "groups".
For the experts who have determined what they consist of would love to get a description of what the cory must have to be in the group.
eg. Bars, blotches,long nose.

Perhaps we can make a list of the groups and their members, would be a great sticky for ID's.

Hehe
Thanks, Kuhni.

I also am quite curious about this and would like to understand it better. Let's see who we can get to check in and what we can dig up.

I just wanted to add my little bit too...
If they are in the same group... does that mean they are actually kin or just have similar traits?
There are so many ways they divide them down the line that it is very confusing to me.

 

[jollysue]

So far I got nothing. This may take some patience and extra work.

Kuhni, what do you know or have heard about an elegans group? Maybe we can start there. I don't even know what to Google.

 

[Kuhni]

I just had heard reference to the elegans group in some of Ian fuller's ids, I believe it refers to the body shape and may also have to do with a level of sexual dimorphism(sp?)? I will do some searching and will add what I found.

That is really interesting, Kuhni. Ian will be proud of you doing this research. It is exactly what he expects us to do. I have no doubt he will be keeping an eye on us and let us know in no uncertain terms if we need to drink drano with Frank.

I am familiar with the aeneus flap, but not the Fuller grouping methed vs Nijsenn and Isbruecker.
I am surprised at the elegans list. I do have the bilineatus and the pantanalensis. I know about the dimorphism in the pantanalensis--hard to miss--but although I noticed some difference in coloration with my San Juan bilineatus I put it down to variations not dimorphism.

Kuhni! You are doing us a biggie here!

You have prodded me.

There seem to be groupings by body, head and snout shape, groupings by marking caracteristics, and groupings by location of capture--as well as the dimorphism spoken of.

So the groupings have to do with the function being looked at. The markings are very frequently the primarly method used to ID a Cory, then body shape and location of capture.

Body and head shape are used to ID the type of environment and food a species might need.

So this is about several areas. An short of "copy / paste" I am not ready to tackle it.

Indeed I do see why I have not been answered yet.

 

[Kuhni]

I hope to create a fairly basic list for ID's something I will probably do when I have some free time perhaps on the friday.

Would love some input on several Key Differences in which to discern the cories.
Of course the in your face group, long nosed corys.
Then Eye Banded.
any more?

 

[jollysue]

You looked at Ian's articles on Identifying Corys 1 the spotted, 2 the banded, 3 the tail spot? I don't know what happened to the striped like panda and weitzmanni. And then he has the shape of Corys--which seems to be catagorizing them for environmental and food needs. I haven't even found the stuff on the elegans group yet.

I found some information on Corydorasworld, seeing as it was available to public viewing I hope he doesn't mind if I use some of the information.

Greetings. Although the information on Ian's site is in an "open" section, for all to view, free of charge, it is still copyrighted material and should not be lifted verbatim and posted elsewhere, without the express consent of the copyright holder. The common practice is to either ask permission first, or to provide a link to the material, which of course, you are not permitted to do, here.

What is the difference with lifting text or lifting a photo, without permission? There is none. Both are wrong.

Ian's a big boy and can take care of himself, but I just thought I'd give you a heads-up that Ian does not take kindly to this behavior and I have witnessed, first-hand, his reaction to this type of disregard for his intellectual property. Not a pretty sight. That being said, I'm sure he'll be more forgiving than I would ever be.

I'd consider dropping him a note with an apology. Additionally, if one wants to contribute to the "scientific" aspects of our hobby, I would recommend a membership to Corydoras World. I feel that the decades worth of information that Ian has compiled is worth the 8¢ a day that it cost to be a member. To say that you are a serious Corydoradinae enthusiast, but you are not a member of CW, is a contradiction.

Just my 2¢ worth from my perspective. - Frank

 

[Kuhni]

I would like to reiterate that I am still only a "young'n", 15 years and I try my best to do the right thing, my intentions in this thread were only to help and inform the users of this forum.
Will edit my post for the time-being, until I get permission from Ian.
I understand the right to his intellectual property, that's why I at least attempted to sum up my findings in place of a direct copy and paste.

I would like to consider myself a corydoras enthusiast, I am even going to establish a fish room focussing on corydoras within the coming months but I cannot register to corydoras world at this point in time, money doesn't permit me.

So once again an apology to all, I will see what I can do.

 

[jollysue]

Frank, I am sorry. I thought we had stayed within the bounds, but if I overstepped I do heartily appologize. I had intended to drop a word to Ian already, but other than the posted thread I have not been online at the same time as he. We will of course let this go.

I am of course a member.

Later. Let's let the thread drop then into oblivion..

 

[Siamese Fighting]

I think a simple "This is copyrighted material" statement would have sufficed, this is all a little OTT.

I know many enthusiasts of Cory who are not registered to "Corydoras World", I see it a disrespect to call that a contradiction of terms.

 

[stiffler69]

Is this code language cause i dont understand a single thing posted lol

 

[jollysue]

I have emailed Ian. Let's let any discussion be limited to Google info and info on TFF until we hear more.

I think, Kuhni, it is more likely I that was doing more word for word than you, although I did not think so at the time. I sort of assumed that spotted and banded Corys were pretty well general terms. But perhaps the reference to Ian's approach to those groupings is over the line. My own ignorance of what is generally accepted knowledge is limited, so it is hard for me to know when I am over the line. This does enter into the intellectual property of Ian Fuller. I guess the problem is, it is almost imposible to discuss these things without reference to Ian's thought!

Well, so much for letting it drop. Maybe we should now be in chit chat!
