CJs Aquatics Posted April 10 Share Posted April 10 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 Share Posted April 10 Looks like corydoras aeneus bronze Cory's 3 Link to comment Share on other sites More sharing options...
Lennie Posted April 10 Share Posted April 10 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...
Pepere Posted April 10 Share Posted April 10 Probably emerald green cories. Corydora Splendens. They look a lot like bronze cories but have an emerald green irridescence that flashes from time to time as they turn if the light catches them right. Theyare incredibly easy to raise from eggs in a breeder box. Dont put more than a few more egg's than you want to keep if you harvest eggs to raise. 1 Link to comment Share on other sites More sharing options...
CJs Aquatics Posted April 10 Author Share Posted April 10 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.

Biotope Biologist Posted April 11 Share Posted April 11 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...
Pepere Posted April 11 Share Posted April 11 Here are pictures of my Emerald Green Cories. Corydora splendens. These are juveniles maybe 4 months old. 1 3 Link to comment Share on other sites More sharing options...
Pepere Posted April 11 Share Posted April 11 I found this difference between bronze cories and emerald green cories.. ”Emerald Green Corydoras are Brochis splendens or more recently Corydoras splendens. They have 12-13 spines on their dorsal fin. They can grow to 3.5".Green Corydoras or Bronze Corydoras are Corydoras aeneus and they have 8-9 spines on their dorsal fin. They can grow to 2.5" ” I count 8-9 on yours. 1 1 Link to comment Share on other sites More sharing options...

CJs Aquatics Posted April 11 Author Share Posted April 11 @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 Share Posted April 11 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 Share Posted April 11 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 Share Posted April 11 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...
Pepere Posted April 12 Share Posted April 12 (edited) Generally,… 29 gallon tank. ph low to mid 7s range before co2 kicks on, Ammonia 0, nitrite o, nitrate holds steady at 20 ppm with daily dosing easy green just enough to replace prior days consumption…. Gh and kh held at 6 degrees. Water temp between 74-76. Lots of dense plant growth, 9 hours of bright light a day with timer for consistency. 3 xtreme bottom pellets fed in the evening.. 6 adult cories in tank about 1 year old. 3 pellets feed the cories, 3 kuhli loaches and other tank inhabitants also go and munch on as well.. also feed other tank inhabitants a pinch xtreme krill or Spirulina in evening. 50% water change Saturday morning. Tap water is 1 degree GH , KH and I add in enough Equilibrium and Alkalinty buffer to bring it up to 6 degrees hardness each. TDS between 350-450.
