I have seen both Corydoras bilineatus and non-bilineatus corys sold as "San Juan Corys".

I'm going to resurrect this thread, cause it's a cool thread to have. Perhaps we should sticky it? In any case, I have an update on my cory which was tentatively labeled as ambiacus. He looks just like my agassazii now! I don't know if it's a color morphing "I wanna be part of the group!" thing or what, but he's almost identical to "Daddy."

Previous picture of "Izzy"


Daddy and Izzy today:

Daddy is the top one. I know you can't see all of Izzy, but trust me, they're nearly identical. I hope you can at least make out the identifiable characteristics on Izzy... what cory do I have here? One who can't make up his mind!

Edit: Oh, help... now it's been suggested that neither of them is Agassazii! Don't do this to me! My brain can't keep up!

~Meow. Thus spoke the cat.~

They are Corydoras ambiacus.

B-b-b-but! But! I thought Daddy was Agassazii! And why did Izzy change so much? I'm so confused now! No one ever protested Daddy's ID before.

I thought I had a thread confirming Daddy's ID... can't find it though. Eeek... this is not cool. *mutters*

*gets all dramatic* This changes everything! Everything, I tell you!

No, not really, it's just confusing

~Meow. Thus spoke the cat.~

I still say C. ambiacus, too.

Kitten, quite a few Corys undergo significant colour changes from fry to adult. As I discovered with my Pandas. Which are covered in black pepper dots until they're 10-12 weeks old.

The most extreme example is Corydoras rabauti. Hunt down pictures of a juvenile and an adult, and they look TOTALLY different!

Here are two adults spawning (T position):

Adult rabauti

This page shows (when you scroll down) a juvenile rabauti. Just take a look at the difference - it's the three-coloured black, orange and white fish, vertically divided, with NO sign of a back stripe at all! Because of this, the juvenile and adult were initially classified as two different species, namely C. rabauti and C. myersi until the truth was revealed during captive breeding.

*pats self on back* yep, I do have a brain, and can at least look up and identify corries

Thanks nick, now who is next for us to attack?

I thought at first that this looked a bit like Corydoras semiaquilus, but there are some differences between that and your Cory. However, a further trawl yielded this: Corydoras fowleri. I'll link both pictures for comparison:

Corydoras semiaquilus

corydoras fowleri

On the basis of these photos, I'd say fowleri is your nearest match.

Ooh, a longnose! These cories are starting to grow on me, though they do look a little odd.

Definitely doesn’t look like C. semiaquilus. The two closest matches I found are C. fowleri and C. coriatae. C. coriatae cories seem to have widely varied body patterns, but none look quite as much like your cory as C. fowleri cats do. I’m going to vote C. fowleri here, too.

Do note that longnosed cories are good at changing their colors; I’ve seen them change from light gray to a medium brown in a short time based on their mood and substrate color. Most all of the “longnosed” cory species seem to have the same base coloration, and they are all capable of altering that beyond the abilities of the normal Corydoras catfish.

Touche. However, the San Juan (in fact, I go to the same LFS as the topic starter) corydoras in my area are NOT bilines, hence my statement.

Yep, it's the Aqualog, All Corydoras +Extra + Supplements....it's really an awesome little collection...it just gives the basics of each cory, but has wonderful pictures to compare with...don't try running to barnes and nobles for it, it'll cost an arm and a leg...I paid $42 for mine including shipping...here's the actual one I bought, don't know how much Cory Addict paid, if her deal is better go with them

It's the Aqualog "All Corydoras" book. I got my copy off of Aquabid for really cheap, and even though it was coming from Germany, the shipping was only a few bucks.

Sort of.

"With this one I would like to see a picture before I committed myself, C. bilineatus are definitely not the so-called "San juan" that We see here in the UK."

He echoes my point in that different cories go by the name "San Juan" in different areas. In my area of the U.S., I'd have to say that C. bilineatus is the cory most commonly known as the "San Juan".

There may have been a true "San Juan" cory long ago, but as with many other common names ("Reticulated cory" for instance), it has spread to other fish.

Hopefully we haven't run too far off the track here. Anybody else need help with their cories? Oh, and Heidi- What is the name of your Corydoras book? I don't have any cory books, and I'd like to get my hands on one that goes in-depth on each species, as yours seems to.

Ian Fuller does seem to agree with me, however.

Jon- I have to disagree, as many cories are known by the "San Juan" moniker, and C. bilineatus is one of them. There is debate over which fish is the true San Juan cory, but as the name is given to different fish depending on the region they're being sold in, it doesn't seem like the debate will end anytime soon.

Now that you meantion it, my corys do look quite a bit like Corydoras elegans "variant I". I had never given much thought to it before because the fish in that picture is so washed-out looking.

OK I obviously am having trouble with my delete and edit button so here we go again:%)

[font color="#C00000"]Cory Addict[/font] I have to agree with Books, it does look like a Corydora elegans, Variante I in my opinion


[font color="#C00000"]Sneaky Pete[/font] For your unknowns I lean towards the Corydoras ambiacus of the truer form. While comparing them to Kitten's ambiacus that were also known as grafi + mellongiros...

[font color="#C00000"]Cali[/font] I have to agree that I think your "Agazzis" is Sodalis, though looking at some of the first pictures I was doubtful...but on relooking and checking it does appear to be a Sodalis...Also the Geryi seems to be more black with white stripes than your little guy is...

OK who is next? I think I'm having as much fun as Nick is:%) heidi

Yes, the San Juan cory and the bilineatus are different fish.
