3 different corys (or only 2)? Help with ID's

Post by FJB »

My first post on this site.
I need help from more experienced Cory connoisseurs.
These 3 Corys where purchased at different times from different vendors, but now are together in one of my tanks. Source localities are unknown, not even a country.

1) The first one I believe may be C. leopardus (please help me confirming or dispelling this).
Note - Relatively long head; No black on adipose fin; Small black blotch on dorsal; Uncolored 1st ray of dorsal; Distinctive forehead pattern (diamond).

2) The second may also be C. leopardus, but I see differences that may go beyond individual variation (opinions, please).
Note - Shorter head; Black on adipose fin; Larger black blotch on dorsal, with straight-line lower edge and different shape; Somewhat different forehead pattern.

3) The third one is certainly different, and I have been unable to arrive at an educated guess.
Note- No "lined pattern" on sides; Short head; Large black blotch on dorsal; Black 1st ray of dorsal, and lower edge of dorsal; Black on adipose; Different forehead pattern; Small, but about the size size as 2) above.

I would be grateful reasons for your ID are given.
The last photo shows both 1) and 2) together, which may help in assessing their similarities/differences.
Many thanks in advance!

Hi FJB,

You have C102, Corydoras trilineatus and Corydoras reticulatus.

Cheers,
Eric

Hi Eric,
Many thanks for your response. I appreciate it.
Regarding C. trilineatus - Could you point out some differences between trilineatus and leopardus?
Since my large C. trilineatus (# 1) was acquired first, I asked folks about it some time ago, stating that it looked like C. trilineatus. However, it was suggested to me that it was not trilineatus but that instead it was C. leopardus.
Many thanks again!

Hi FJB,

Trilineatus looks similar to leopardus, but trilineatus is a short and round snout species. C. leopardus is a high-bodied, straight snout species, as is C102.

Cheers, Eric
