We have a C. reticulatis at work that came in as a contaminant in a shipment of C. sodalis. That's what yours are, all right.

I'm going to say that your mystery cories look like C. bilineatus. They are definitely another elegans-type (bunches of them in this thread), and the other elegans group cories don't match up as well. So, [link=C. bilineatus]http://www.planetcatfish.com/images/full/callichthyidae/corydoras/bilineatus/1.jpg" style="COLOR: #808080[/link].

Hmm... that's why I didn't think my cory was bilineatus... every bilineatus has brownish marking while my guy has black markings, though the markings themselves are similar. I dunno... it's confusing... I'll try to get better pics.

Kitten, your cory looks more like C. nanus rather than C. bilineatus.

I'm not your neighbor, you Bakersfield trash.

Updated pic, for comparison's sake.

Huh. You know, Natalie may be right in that your fish is a C. nanus. A difference between C. bilineatus and C. nanus is that bilineatus cories have more greenish side stripes, and C. nanus stripes are more brown/black. It's tough to tell from your earlier pictures, but the latest one shows more black on the stripes. If that's so, then C. nanus looks like the most attractive choice. Good call on that, o mighty addicted one.

OH Goody, tomorrow when I have more of a brain I'll pull out my Corydora book again It really does have excellent pictures and close ups to help identify zillions (ok not that many, but most, including the "C number" Corries heidi

OK, putting this picture up means I'll probably have to edit this album entry AND my web page, but here goes

This was sold to me as Corydoras agassizii. Which it obviously isn't. based upon extensive reading of the Lambourne book on Corydoras, I alighted upon Corydoras bolivianus. Since then, however, I've found that this name is not considered valid by PlanetCatfish. Apparently C. bolivianus is a junior synonym of C. geryi. Mine resembles the paratype fish that was named C. bolivianus. The reason I rejected C. sodalis and other similar species was the lack of a large prominent black blotch in the dorsal. Instead, mine had reticulated markings that more closely resemble the C. geryi/C. bolivianus type fish.

This page also features geryi. The male looks quite a bit like my former aquarium inmate. Let's see if Sirbooks can wave the magic wand on this one

I'm not able to view your picture (the school computers blocked your site), but I think it may still be a C. sodalis.

As you can see, there is a little bit of reticulation in the dorsal fin, but there is no large black spot. You may have been thinking of C. reticulatus (see the last picture in Janna's above post), which looks the same but does have the black blotch. Sodalis cories are more common than the other similar species, which is why I'm leaning in that direction for now.

Your school computers blocked an MSN Photo Album with no adult content? Pah. Net nannies. I despise them all. ]:|

An alternative host for the picture is here.

I did originally consider C. sodalis, but this is a species that I don't think appears that often in UK imports, and the Lambourne book's comments made me think of bolivianus as follows:

C. bolivianus Nijssen & Isbrücker 1983 - first coll. G. Loubens 1982. Distribution: Bolivia: Beni - Rio Mamore. Max SL 65mm. C. bolivianus shares the same colour pattern as C. sodalis and C. reticulatus, but it is a much more robust species, and the reticulated colour pattern extends into the ventral region. All fins heavily pigmented, but dorsal fin blotch absent (this is present in C. reticulatus).

Plus, the book says this about C. reticualtus:

C. reticulatus Fraser-Brunner 1943 {Mosaic Corydoras} - described from aquarium specimen, but some of the first specimens collected W.G. Scherer 1935. Distribution: Brazil: Rio Amazonas at Monte Alegro; Peru: Loreto - Rio Ampiyacu, Rio Nanay. Max SL 65mm. C. reticulatus shares the same colour pattern with C. bolivianus and C. sodalis. C. reticulatus and C. sodalis are extremely variable in colour pattern: the body can be covered with small irregular dots and spots *or* large spots and blotches which link up to form a reticulated pattern - there is also a great variation in the reticulated pattern. The caudal fin can have 4-8 irregular vertical bars. In C. reticulatus the dorsal fin has irregular pigment and a black blotch (some specimens lack the irregular pigment, but the black blotch is always present). C. sodalis has scattered pigment in the dorsal fin and in some specimens this joins together to form 1 or 2 horizontal stripes. C. reticulatus is reported to have bred under aquarium conditions.

And this about C. sodalis:

C. sodalis Nijssen & Isbrücker 1986 - first coll. T. Hongslo 1971. Distribution: Peru: Loreto - Rio Yavari, Cano de Guavariba into Lago Matamata; Brazil: Amazonas - Costa de Capacete, Rio Solimões at Benjamin Constant. Max SL 65mm. C. sodalis shares the same colour pattern as C. reticulatus and C. bolivianus. This pattern is extremely variable. The upper half of the body may be covered with small irregular dots and spots, or large spots and blotches, which link up to form a reticulated pattern. (In C. bolivianus this pattern extends into the ventral region). Scattered pigment in the dorsal fin sometimes forms 1 or 2 horizontal stripes. (In C. reticulatus there is scattered pigment and a dark blotch on the dorsal fin, whereas in C. bolivianus, all the fins are heavily pigmented and there is no dorsal blotch). The caudal fin may be covered with small spots, forming up to 7 irregular vertical bars, but, in some specimens, the pigment may form oblique bars in a chevron-like pattern. The dark line along the junction of the body scutes (when present) can be either straight or zigzag and in some specimens, a broad unpigmented area is present above this line. Breeding: C. sodalis is known to have bred under aquarium conditions.

The green iridescence that appears on C.geryi on PlanetCatfish also appeared on this fish under the right lighting conditions, and the descriptions above led me to consider that my fish was C. bolivianus. Hopefully now you'll be able to see the pic (and at a larger magnification!) without net nanny interference

Now that I can view your cory, I'm seeing some differences between it and C. geryi. For one, the lines of the reticulated pattern appear to be thicker on geryi cories than on your cory, which matches C. sodalis in this respect. Plus, the dorsal fin of male geryi cories looks taller than and has more reticulation than your cory’s dorsal, and those of C. sodalis. As a final point, the green sheen. I’ve seen a few sodalis cories that are capable of looking “green” when conditions are right. If yours is a sodalis as I think it is, it wouldn't be alone in feeling green.

Your cory
C. geryi

Hope that helps.
