Emerald Cory or not?

Well, several months ago I got some Emerald Green Corycats from petsmart, we all know they sometimes fail at many things including proper labels...Ahem, anyways, two of them were big when I got them, by big I mean huge in comparison to the smaller youngins you usually see. Me and petshop lady both assumed they were adults...shouldna done that, right? Haha, well, they've been in my 55 gallon tank a little over a month now and grew at least an extra inch to add to their already three inches they had when I got them. I have a photo, sorry it's not too great, of one of my big boys(I was told the bigger ones were males and the smaller ones I have are females). This is actually the smaller of the big ones, by about half an inch, and a red platy next to him being all ziggy, sorry. lol

Oh yes, my question...is this really an Emerald, or were they mislabeled? They're three times the size of my other cories, but I can never get photos of them together, I have tried. >< And yes, he had a messed up dorsal fin, it never did grow back in the four+ months or so that I've had him, never got worse either, I just figured it was permanent damage. =(

The term "Emerald Cory" is a common name and it is used for both Brochis splendens and Corydoras aeneus. Not mislabeled, but it is, as named above, a Brochis splendens. Different common names are used in different countries or regions within a country. This is why you should use the scientific name if your looking for something specific.

Hm, so I should assume mine are just "Freaks" then? They're over an inch longer than they should be. Both are around or over four inches long, and those species are only supposed to get three inches long. lol If that's the case, should I be worried about anything, like illnesses or trouble of any sort?

Then they are giant Brochis(brochis britskii) reaching 13cm(5in).

Give them the same care as the broze corys(corydoras aeneus)

Try to get 4 more they want to be in groups.

That fish in the photo is certainly a Brochis, but it may be B. multiradiatus which I believe is the largest species at around 4 inches.

Care as set out in our profile for Brochis splendens [click the shaded name for the profile] is the same.

The B. mltiraiatus has a more of a long nose and a higher dorsal fin.

I have a book of David Alderton(encyclopedia of aquarium & pond fish) that says B britskii can reach 13cm.

I would question that length. Both Planet Catfish and Fishbase give up to 9 cm or 3.5 inches for this species. Some might get a tad larger perhaps. But regardless, it may be the fish in this photo.
