CJs Aquatics Posted April 10, 2023 Share Posted April 10, 2023 Hey all, picked up 4 of these today to add to a community tank, they were sold to me as “green cories” but I was hoping someone could positively identify the scientific name for me as there are so many different types of “green cories” out there. Ideally I would have liked 6 but I don’t want to increase the colony size until I’m sure which species they are, below are some photos, sorry I’m a poor photographer… 1 Link to comment Share on other sites More sharing options...
Colu Posted April 10, 2023 Share Posted April 10, 2023 Looks like corydoras aeneus bronze Cory's 3 Link to comment Share on other sites More sharing options...
Lennie Posted April 10, 2023 Share Posted April 10, 2023 I would let them color up with some good care. They remind me of orange ven. too 1 Link to comment Share on other sites More sharing options...
CJs Aquatics Posted April 10, 2023 Author Share Posted April 10, 2023 This is where it gets hard, I was guessing Aeneus likes @Colu said but I’m not positive so I don’t know which ones to buy to increase the colony size, the guy said when I asked what they were “just regular green cories” but that was all the info I received at the time, I got them anyway bc who doesn’t love a good mystery, would love to source some more but want to get the same species Link to comment Share on other sites More sharing options...

Males are considerably smaller in size in my experience, especially next to females. And females have more round bellies/bodies Edited April 10, 2023 by Lennie Link to comment Share on other sites More sharing options...

Biotope Biologist Posted April 11, 2023 Share Posted April 11, 2023 Corydoras aenus are sometimes called green cories. Common names are annoying but if the distributor is to be trusted its probably Corydoras aenus. 3 Link to comment Share on other sites More sharing options...
CJs Aquatics Posted April 11, 2023 Author Share Posted April 11, 2023 These appear at rough glance to have about 9 I’ll have to double check but that’s what it looked like Link to comment Share on other sites More sharing options...

These are juveniles maybe 4 months old. They are adorable. Hard to say for now exactly but I am leaning towards 2 m and 2 f. Just a guess Link to comment Share on other sites More sharing options...
CJs Aquatics Posted April 11, 2023 Author Share Posted April 11, 2023 @Lennie I think you may be correct they are traveling in pairs together and one is bigger then the other in both pairs, I doubt I could be that lucky but maybe, still gonna try to get a pic when I can Link to comment Share on other sites More sharing options...
Lennie Posted April 11, 2023 Share Posted April 11, 2023 Maybe this pic of my sterbais helps. Male is clearly different than females 1 Link to comment Share on other sites More sharing options...

Common names are annoying but if the distributor is to be trusted its probably Corydoras aenus. It's kind of ridiculous how many things are forms of or labelled as aenus corydoras. There's so much confusion and it's really difficult to get the "right one". @CJs Aquatics This came up I want to say 2 months back and it was almost the same situation. One thing that's frustrating from my side is that the two corydoras that get confused are often very different sizes in the end. Emerald green vs. bronze corydoras. Bronze corydoras: https://www.planetcatfish.com/common/species.php?species_id=51 Emerald green: https://www.planetcatfish.com/common/species.php?species_id=114 You can see it in Pepere's photos as well as yours there is a. Iridescent green along the bottom of the body. Keep an eye on how they develop and color up. From what I have seen the emerald greens get a bit chunkier and taller compared to others. They are bigger bodied and taller. The dorsal ok the emeralds looks to be a little bit larger as well, but there is a variety of photos on the planet catfish site for each species. I'd also review this one. "Green gold corydoras" https://www.planetcatfish.com/common/species.php?species_id=111 On 4/10/2023 at 5:28 PM, Pepere said: Here are pictures of my Emerald Green Cories.

Miska Posted April 11, 2023 Share Posted April 11, 2023 I have no idea what they are- but I want them. Gimme. So cuuuuute. Why are cories the cutest of the fish? 1 1 Link to comment Share on other sites More sharing options...
Odd Duck Posted April 11, 2023 Share Posted April 11, 2023 Definitely Corydoras aeneus AKA bronze cory AKA green cory. Once you know about the dorsal fin rays and see them a couple times it becomes more obvious as your eye gets more practiced at seeing the difference. C. splendens AKA emerald cory, has a notably longer dorsal fin and to me a slightly longer, straighter nose plus proportionately give the effect of a bigger head in relation to their bodies. They both have enough natural variation in base color to make it not reliable in telling them apart. If you ever get the chance to see them side by side (not necessarily in the same tank, just the same day), the differences will become more obvious. They “hold themselves” a bit differently, like 2 people the same height and hair color, similar faces and builds, but they move differently - if that makes sense. C. aeneus tend to breed very easily, but C. splendens tend to not breed quite so easily from what I’ve read, but they are still cories and couldn’t really be called difficult to breed from what I understand. I’ve bred plenty of aeneus but haven’t had splendens in years and have never tried to breed them. 2 1 Link to comment Share on other sites More sharing options...

Thats it… I’m only going off what I’ve read and in comparison to aeneus which are the rabbits of the fish world when it comes to breeding. 😆 Good to know your splendens are easy breeders, too. 😂 🤣 1 Link to comment Share on other sites More sharing options...

Thats it… Water parameters? Water parameters make a difference between easy to breed and hard to breed; softer water is always a winner with sa fishes. 1 Link to comment Share on other sites More sharing options...
