Little help with ID

Maybe I am just having a bad day. Got my first ever internet purchased fish in today. 3 of 6 wild juliis were dead, one all but, the two expensive fish I ordered were listed but not in box, and I can't figure out these cory nanus. The little pandas are doing awesome, however.

Could Someone WHO KNOWs please (without a dang ad across the middle) please post a Good picture of a Julii and a good picture of a nanus...if possible, same aspect. Also a false julii if available. I did not see nanus in the profiles. The Julii is fine there, I think!

I swear, it appears a lot of the pictures of Nanus that I find are really Julii...if Julii have dots and nanus have reticulated head as some sites say.

Anyway, thanks a ton in advance. Any comments or other guidance are appreciated, too

Here's the julii:

Julii Cory (Corydoras julii) Profile

If you go to our Fish profiles you can see the proper pictures there.

If you don't stand up for something you'll fall for anything...

Thanks, I got the Julii in the profile, I edited that in later, sorry, it is the nanus that is troubling me. I have four that are pretty clearly not Juliis but two supposed Nanus, look Jullish to me, and they are not supposed to I don't think.

Greetings. Supplying pictures of your fish would help. There is absolutely no way that these to fish can be confused. They are as different as night and day. One is gold and brown and the other is black and white. Additionally, C. nanus are in the "Elegans" family and have an entirely different body shape.

Pics, please. - Frank

I keep approximately 95 species of Corys and have spawned 61.

Very doubtful that you have C. julii as they are quite rare and without knowing where the fish were collected, you will never know.

Thanks for your posts. I appreciate them all.

Next I have to apologize for awful pictures, I have not mastered focusing through the glass, and the water is still a bit hazy.

Here is what I am calling the Julii, I defer to Coryologist and figure it is not, and it matters not to me, but I like these guys, You can see the pink. Believe it or not, it is better. I lost another one today, so I am not down to only 2. Grrhhhhhhhhh!!



As you can kinda see, the head is more or less dotted (I know bad pic) which is I think a marker, but then I found a Spotted head strain of trilineatus (sp help).

Here is the other. I got six of these, listed as Cory Nanus. Don't know. They don't appear very dwarf to me, they are pretty big, and all are doing well.



By the way, though a bit pink at gills, they are very very active. Also you can see the probably trilineatus in the background, here.

Hope you can make some assessment with these photos. Have to help with daughter's "senior project" then I will focus on getting better pictures.

The first fish is a C. trilineatus in not very good condition.

The second fish appears to be C. elegans. They are an extremely variable species.

Thanks Coryologist.

The first is one of two surviving from 7 shipped. He is still going strong this morning, hopefully he will make it. Thanks for the ID's. Really appreciate it, not that what I had mattered a lot, just wanted to know, since I could not resolve fish with pictures with descriptions given at purchase.
