[Sarah73]

Always on the move geez! They are soooooo hard to get a good picture of.

Always on the move geez! And my smallest and biggest cory in the 2.5! They are soooooo hard to get a good picture of. View attachment 461355View attachment 461356

Did you get those two together Sarah?
Or is it possible they are a different species ?

Which two? The little ones are slowly growing color. The bigger one is turning albino so I'm excited! And the bigger blue spotted corydoras is the female!

 

[DoubleDutch]

I meand the blue spotted ones.

I got them together. All from the same bag.

Ok, think I misjudged the pic (color and size)

There are no breeding instructions on how to see if the blues will breed. It's so frustrating! Sometimes the males will go on top of the females....weird. And I can't get good pictures of them because they are ALWAYS on the move.

 

[DoubleDutch]

Maybe on Planet Catfish

Already looked. It's unreported

 

[DoubleDutch]

Mmmm okay.
Are you on FB ? There are several groups with guys who bred almost all Corys.

Nope. Got hacked from it. Never going on again.

 

[DoubleDutch]

Okay !

[Sarah73]

Okay !

Like I said I'm going to give them a 20 long to themselves. Add almond leaves, Amazon's, Horn wort, etc. Make it very planted.

I don’t think those are C.melanistius aka blue spotted cory, melanistius doesn’t have the bars in the tail fin

 

[DoubleDutch]

And waterchange with cooler water when airpresure changes

 

[Sarah73]

Here. Are you sure?

 

[Coradee]

Let’s see what DD thinks, he’s better at the spotted ones than me but I’d guess at them possibly being C.delphax

He's the one who said it was a Corydoras melanistius.

 

[Coradee]

Oh, well I’m pretty sure they aren’t melanistius DoubleDutch

 

[Sarah73]

Well either way they are both unreported for breeding!

My tank is going CRAZY! more eggs for me

 

[DoubleDutch]

Serious ??? Did I ?
These ones are so incredibly difficult to ID, that I try to be so careful as possible in these cases. I asked the question because C.delphax crossed mind hahahaha.

I doubt we can ID properly if we don't know catchinglocality.

[Coradee]

Several people have bred both, though they aren’t easy I believe, planet catfish is a bit out of date there.

Edit: thanks DD so we sort of agree they could possibly, might be C.delphax hehe

The thing that really interests me is the fact that they're dark in color, with a lighter stripe between their dorsal fins and eyes.
This is the site I use to identify Cory species Fish Identification
There's a couple that look somewhat like yours, but no dead ringers. I have to wonder if yours could be some sort of hybrid, which would also explain why you haven't been able to get them to breed. But it's also possible that they're some sort of very obscure species that is poorly documented. Interesting that we know so little about a Genus of fish where some of the species have been kept since the 1800's. In fact we don't even fully understand how they fertilize their eggs! They're so common, yet so mysterious.
