Cory Trilineatus and what else? (warning: picture heavy)

Post by amergim »

These two pictures look like trilineatus

But these next three, I'm not so sure. Ian suggested they were juvie trilineatus when I posted a while ago, but they are now almost as big as the first two, and they still have a different pattern, especially the head.

Now, these next two, I got them as punctatus, which it seems obvious they are not. Any ideas?

Even though the pattern is a bit different, they're still C. trilineatus. They are very variable.

The last two pictures show C. leucomelas I think.

Cool. I wanted to make sure I don't mix species and end up with hybrids. Thanks.

If you keep enough of each species then there is alot less of a chance of them cross breeding. Love ur C. leucomelas

The first two images belong to the fishes with straight scutes junction zigzag, the eye above the lines shown in the drawing of the type specimen and head arched above snout I called false Corydoras trilineatus in

Type specimen of Corydoras trilineatus is high and has the eye below the extension of the scutes junction zigzag
and on the line connecting snout tip and dorsal spine root. Head is not arched above snout, but before dorsal fin as in the last image.
Last three images may represent Corydoras trilineatus.

To me they're still C. trilineatus (all of them).

Just different varieties.

I try to keep at least six of each if I have to keep them in the same tank for any reason.

The netted ones are leucomelas without a doubt. I have two mixed in with my trils, very easy to tell apart.
