need held in identification of my new corydoras

[balous]

Hi,
since a week I have 8 new Corydoras.
They have been ordered from the zoo-shop as C. punctatus WF,
but the Corys are no C. punctatus.
I have checked all my books and the internet but I have no idea,
which Corydoras I have bought.

All I know is that they are WF Corydoras.
They are appr. 4,5 - 5cm total lenght.
Some have a type of wormlines on their heads (maybe males?).
They are not active during the day, but in the evening they start to live
Not like all my other Corydoras (metae, axelrodi and schultzei).

I have made the pictures 1 hour after I have bought the Corys.
Hope they are good enough and you can help me to give my Corys an ID.

Sorry, if my english is not as good as it should be.

Regards from Germany

I was thinking

Corydoras agassizii

, but there are another couple of fishes that are pretty similar.

For example:

Corydoras ambiacus

along with a number of C and CW number species.

Hi balous,welcome to planetcatfish .
I agree with matsp,at first glance its does look very much like C.agassizi.The reason these cories was sold under this name C.punctatus is because these cories belongs to the C.punctatus group,the true

Corydoras punctatus

is actually quite rare.

Hi,
I have posted the photos in a german Cory-Forum, too.
They think it´s C. ambiacus. Very various species
Hope they will breed in my aquarium.

Just about every spotted Cory exported out of Peru and Colombia are called C. punctatus by the exporters.

It is not C. agassizii either, in this species the first two or three dorsal rays are black from tip to base and this black pigment may also extend down into the body.

The fish pictured is as near to C. ambiacus as you can get.
