Corydoras eques?

Ran into some corys at local LFS which were marked eques. Can't find it in the KB so was wondering if this was a synonym or a color morph of another species.
Also would greatly appreciate some info on them if anyone has any. Google turns up pretty thin information. Mostly discussions on the similarity of aeneus and eques. And on a side note how do corys do in a mixed batch?

CAS: Current status: Valid as Corydoras eques Steindachner 1876. Callichthyidae: Corydoradinae. Distribution: Amazon River basin, Brazil. Habitat: freshwater.

I'm no Cory expert, having kept only a few species and currently only one, but a mixed batch of (closely) related species nevers sounds like a good idea - I feel.

Here's one tip - ignore the Corydoras section in the KB until further notice. Must admit I've no idea how reliable that part of the site is. /unsure.gif" style="vertical-align:middle" emoid=":unsure:" border="0" alt="unsure.gif" />

We had C. eques in at the shop and as far as I remember it's a darker-bodied fish than the bronze cory with a prominent orange shoulder marking. No clue how related the two are though and don't even recall where C. eques is from?

In my experience, and some of the long-snouted species aside, corys normally do fine in mixed-species groups as they're gregarious fishes by nature, though if you intend on breeding them it should obviously be avoided.

KK, thanks for the info guys.
Yea they do look like aeneus but with a fresh coat of paint sort of. Nice looking fish IMO so would like to find out more specific info on water chem, temp and such. I'm guessing they fall into general cory parameters.

The guy said they came from Peru, but I'm pretty sure he meant they were just imported from there. Didn't seem very informed about them.

is this something that u would say applies to all species or... I mean two species of tetras can coexist in the same tank, no?

Never assume for the odd chance one makes the incorrect assumption; that would a shame /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> Surely there must be someone who knows water parameters for this species /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

Personally I wouldn't keep anything together that might crossbreed.

Be extra careful when thinking about purchase of these fish as some aeneus types are being exported from Brazil as eques. The nicest version of the 3 types of eques is stunning and distinguishable from aeneus at 5 miles. Two come from Peru btw. The more attractive one is Brazilian. I'll try and get a photo and send it to you.

I would also add that some aeneus types have been selectively bred in Poland and exported as something they are not!

Thanks for the heads up guys.
The batch I'm looking at comes from Peru. They do look like aeneus but you can tell the difference. The color is more vibrant and more of an orange/brick than the regular brownish of the aeneus. They are in two tanks next to each other. I did read about all the mix ups with aeneus and the painted specimens and such but since I have no experience with fish ID a picture of the real thing would really help Pablito.

Their closest relative is Corydoras rabauti. A good guide for ascertaining if they are C. eques is the price. C. eques are selling for about £15 - £20 each.

Look for the orange stripe down the centre of the back.

Nice pic mummymonkey.
Thanks for the info. The ones at my LFS are probably not really eques then. Not that pricey. Although, they are very similar to the one in this picture. Maybe they're one of the peruvian types pablito mentioned. Will check for the stripe next time I'm there.
If the pic in the KB profile is accurate they shouldn't be rabauti. Too yellow. Maybe I'll take a pic if they don't mind. I'm pretty sure some of you guys could ID it properly. I don't really mind if they are in fact eques, I'm planning on stocking my tank with a group of corys and these looked great to me. But I'd still like to know what species they are so I can check whether my water parameters are ok for them.

Nice pic mummymonkey.

My pic's no more illustrative than mummy's. A true Brazilian eques. Be interesting to see what the fish look like at your LFS. If they are longer and slighter in the body they could be melanotaenia, given that you've mentioned the yellow hue.

Ok, will try to take a pic and post it.
U misunderstood. I meant the rabauti mummy mentioned seems too yellow to be the fish I'm looking at, from the picture in the KB at least. And the scales on the melanotaenia seem too pronounced. ''Mine'' are similar to mummys pic but the body is more orange and I can't be sure about the stripe on the back. As for body shape they are exactly the same as say a paleatus. I'm a newb so I can't be sure if that would be considered longer and slighter. I wouldn't say so.
My guess is they may be eques, but from Peru. I doubt the LFS would falsely advertise them as eques and then sell them cheap. Little more then aeneus.
Anyway, thanks a lot for the help and interest. I'm sure there's no point in u trying to guess what I'm talking about based on my exceptional descriptions /rolleyes.gif" style="vertical-align:middle" emoid=":rolleyes:" border="0" alt="rolleyes.gif" /> /rolleyes.gif" style="vertical-align:middle" emoid=":rolleyes:" border="0" alt="rolleyes.gif" /> /rolleyes.gif" style="vertical-align:middle" emoid=":rolleyes:" border="0" alt="rolleyes.gif" />. As I said I'll try to take a pic so u can sort this out for me.

Well guys, seems I've hit a snag. Went to the LFS tonight and they've sold the bunch. Not a one left. It breaks your spirit sometimes.
Anyways, thanks for the help again.
If they get a new batch anytime I'll get the pic so we can hopefully conclude this fiasco of mine.

Talking about hybridization: it would be really nice to have some data on which species hybridize and which don't.... imho there is nothing wrong in mixing cories of different species if they are all in sufficient numbers and known not to hybridize...
I keep most of my cories separately, except for mixing c.panda with c.metae... known not to hybridize and indeed while both species regularly spawn, nothing funny has happened. I would have mixed some others if I had any sense which may or may not hybridize.

I agree. That would be useful info. And not just corys. Apart from an extensive database the next best thing is probably making a thread here: will X hybridize with Y? Seems there is a lot of members with loads of experience in keeping and breeding corys on here.
I'm in the process of stocking my tank and I'm having difficulty finding out which species of tetra would be OK with each other in that regard. With corys it's even tougher since most of them are in the same genus.

It wouldn't surprise me to see a C. panda x C. metae cross. Both these species are known to hybridise fairly easily and I've peronally seen C. metae x C. axelrodi. You always run the risk when keeping corys together. They don't even have to be similar in looks. See here for a panda x paleatus cross.

Very interesting photo...thanks...

I would not bet my life on this, of course, but I've been told that metae X panda does not happen before putting them together, and no hybrid came out from the tank where I have both spawning most of the time. I even have a metae male that always tries to spawn with pandas... still nothing.

Finally added a profile for this species. Is there a definitive way to tell it apart from the Peruvian fish?
