Large Cory Cats - C. aenus or B. splendens or ???

Hello,

I was visiting my favorite LFS yesterday and found these guys. They were unlabeled and sold to me as "medium cory cats". Compared to my other cories, these guys are not medium, but LARGE (2.5-3 inches, 63-76 mm). They are almost disturbingly placid. They seem to have a longer "snout" (my term :D ), so I was inclined to think they are Brochis splendens, but I'd certainly like your thoughts.

They seemed to be in good condition, with the exception of some damage to the dorsal fins, which I'm thinking was from the rosy barbs they were housed with, as the other fins (and the fish themselves) seem to be in fairly good shape. (One has a single white spot on its head, which I'm going to post about separately...)

Fish pics are posted on my aquarium website at http://homepage.mac.com/jen.nelson/PhotoAlbum2.html and are the ones labeled "Large Cory Cats".

Thanks in advance,
Jen

Jen,
They are Brochis. Check the Cat-eLog.

Thanks... Like I said, I was leaning toward Brochis... someone else from the forum (in respone to a different post) suggested Brochis multiradiatus. I could see that, especially given that these guys have a prominent "break" in their forehead when you look at them in profile. I tried to count dorsal rays and have come up with 14 or 15, which seems to fall between the values I've found here and elsewhere for splendens and multiradiatus... Thoughts? Any thoughts on my white spot issue?

Thanks y'all,

Jen,
Difficult to tell from the pics, but it just looks like a typical scratch. These are common on the head as shipped specimens burrow into the corners of their shipping bags and rub the tops of their head raw. Keep an eye on it, but I am betting it will either clear up or just be a small scar.

in my tanks i have some B.splendens and multiradiatus.
And also some "B.splendens" as yours, a little more "slime-line" than the usual B.splendens, "break" in the forhead, also having about 14 rays in the dorsal fin...When i bought them, i was happy getting some multis for the price of a splendens..but they aren't multiradiatus. Theses guys are have a much longer snout, body is a little higher and much more rays in the dorsal fin.
This individual also does not school as intensive as the other individuals...and is more shy than the others.
We'll see what happens when it grows up...it's now about 6cm TL. Probably it's within the range of B.splendens, as this species shows a wide distribution form Peru inthe West to Rio Tocantins in the east.

You might also wish to know that the cories labelled "C. agassizi"in your site are actually Corydoras sodalis.

Yup, got that from the other thread I started about them. Thanks, y'all!
