I Think They Gave Me Bronchis Instead Of Corydoras?

[Katty]

Yesterday I went to the lfs to get four bronze corydoras. I came home, put them in QT and everything seemed alright. Except this morning I turned on the lights and really watched them and noticed that there were two that had a sort of greenish shine with very light speckling on their faces. I'm thinking that these two are possibly some kind of Brochis, based on what I was able to google search up.

NOT MY PICTURE, but the two greenish ones look exactly like this:

Then the other two aeneus, definitly look like bronzes and have the same brown-white color as eachother, again, NOT MY PICTURE but they look just like the pic:

So... I just got these yesterday, should I take back the two brochis? They are all getting along and inter-mingling, but really, if I was going to get two different species of corydora (or genus as it looks like now), brochis would not be my first choice. I originally wanted to mix bronze and leopard but decided it would be better for the fish to be all bronze. Except, now they're not all bronze anyways But the hassle of wrestling them out of the tank and taking them back to the store is a little bit inhibitive... Should I take them back or does it not really matter to them? Are brochis very different from corydoras aeneus?

To top it all off, one of the suspected Brochis has one white spot on its flank... Good thing it's quarantine I guess.

If you can, try and have a count of the number of rays on the dorsal fin, as this will give you a good idea of which Brochis species this is. If it is close to 17, you could have sourced some bargain B. multiradiatus, which normally go for ~£20 a pop (I got a better deal than that, but it was still a telling wound to my wallet for my group)!


Edit: Just re-read that both photos are not of the actual fish

You don't think it's a bronze though? I don't really care what kind of brochis it is tbh... It could be a $50 dollar fish but that doesn't really help out with me wanting a school of just plain old bronze. I don't really have the time or resources to try and sell fish. Thanks though.

Hi Katty

If they look like the picture, they are brochis. Take a look at their tails; if they have a half moon shape they are most likely brochis. It's not unusual for B. splendens to be sold under the name of green corys. That is, by far, the most common one.

While they are not corydoras, they will get along with your corys. However, if they were mine, I'd prefer to have a bigger group of C. aeneus. If there is a white spot on one of them, it might be a good idea to get them out of the tank and take them back to the store if they will have them.

In any case, whatever they were I went and changed them out for some actual bronze. The new bronze I have now are really fat looking, females maybe?

Hi Katty

It could be you got a batch of all females but probably not. The easiest way to tell is to look down on them from the top. This is a batch of wild caught C. aeneus I bought some time back. Out of the bunch, I'm pretty sure there were three males, two females and two more that I wasn't entirely sure about but might have been female.



Unless you intend to breed them it doesn't matter, but I like to have more or less equal numbers of males and females.

Good luck with them.
