I found these corys at my LFS, and I have a good feeling that they are C. julii, but there is still some doubt. They are still young, with the biggest one being a bit over an inch long. They have mostly singular spots, but some of them are connected, as in C. trilineatus. The line on the side is broken, and the flanks have no vertical stripes, a trait that is normally seen in C. trilineatus. Also, they have a very short, round nose, which is more pronounced in C. julii

So would anyone care to give me a positive ID on them? Here are the pictures (they are nearly impossible to get pictures of now that they've settled in, so I had to take them out to get the good shots).

These pics are alot better than the first ones I saw, but I m still curious

C.Ambiacus ?

Ummm... C. ambiacus doesn't look much like C. julii at all...

C. ambiacus

It's Gotta be a C. julii for sure!!

In my opinion, it can still be a C. trilineatus. The stripes on the caudal fin make me think so.

To much bold spots on face area and head shape forwards me to C Julii. But it's just my Opinoins also.

I have covered this ground many times before, C. julii is very infrequently imported and the chances of it turning up out of the blue in a LFS is very slim. Their natural range is in the eastern part of central Brazil near Alto Parnaiba in a small tributary of the Rio Parnaiba. When viewed from the front it is quite slim.

On the other hand C. trilineatus is a chunky looking fish, which has a very variable colour pattern, from bold wavey lines and blotches to quite fine spotting. The bigest difference is that C. trilineatus is found predominantly in Peru from the Rio Ampiyacu.

I would estimate that there is a distance of may be 2000 miles between the two species.

C. ambiacus has also been mentioned in this post, it is also a vary variable species but bares no resemblance at all to C. julii or C. trilineatus.

So you're saying that my corys are C. trilineatus?

Without being able to determine the true source of your fish I would still favor C. trilineatus as being their ID.
