So the slightly more elongated snout in c.delphax is the best way of distinguishing between that and c.ambiacus?

In which case, Chef, Ian has ID'd the top one in this thread: -

http://www.planetcatfish.com/forum/viewtopic.php?t=14163

as c.delphax. This fish does not have a brownish colouration. I'm thinking that the difference lies in the dorsal colouring (how it bleeds into the body) or the 'orange' blob on ...

I would have to say c.elegans although as Kim said, it could be C41.

Got 2 of this type as a freebie (makes a change for me!!) were sold to the guy as c.punctatus . Typical for all types of corydoras that look similar to this to be labelled under the bracket of punctatus !!

Anyway, I'm very confused as to correct ID between delphax and ambiacus . Could someone ...

Sorry, that was my fault as I was the one that suggested it.

As we are all intrigued to know what species these are, it may be a good idea to move it into it's proper and relevant section anyway.

Sorry again!!

Well, fullt adult delphax generally lose their spots and are quite easy to distinguish.
Also, male delphax have black on their first soft dorsal ray which is usually elongated further than the main dorsal spine.

c. agassizii and ambiacus are very difficult to distinguish because the patterning is ...

The more I look at this one the more unsure I'm becoming!!

Maybe you should repost this in the What's my Catfish? section, to get more opinions!

My best guess would either be corydoras ambiacus or corydoras agassizii.

Actually, pH must have been more like 6.8-7

When my pygmaeus were spawning regularly (once a month at least) they were at a much higher temperature than Ian's.

These were my readings.

pH = 7.2
KH = 3
TDS = roughly 200ppm (GH = 12)
Temp = around 25.5 C

I had a breeding group of 8 in an 18" x 15" x 12" tank.

Good luck with yours!!

PS. I ...

I got your book this morning Ian, even signed by you!!!
Thanks for sending it so quickly!!

The reason why I have questioned some of my initial thoughts are due to the similarities mentioned in the Remarks sections.

Btw, the fish to left of centre in picture 1 and the fish in picture 2 are the same ...

These similarities are so tricky!!

I'm convinced that 1 and 2 are different. The dorsal spot is in a completely different position. In 2 it is in the same position as for c. trilineatus, in 1 it just about comes into the dorsal from the body.
Also, and more obviously, 2 has a heavily reticulated ...

Thanks

I don't think Number 1 is c delphax as I have these and they look nothing like.



The C131 is behind and above the delphax

Have had all these fish for quite a while and never really known exactly what they are, just educated guesses!! However, buying Ian's ID book from him has inspired to find out once and for all.

Can you confirm my initial ID's please?
Thanks to Corydoras World for hosting the pictures.

They all ...

1) Looks like a c.blochi blochi. I have one similar but where the body spots are far more prominent. I'd be interested to see the id on that

2) Definitely elegans group. Again, I have a few similar, labelled as c. sp. 'San Juan'

3) Again, I think elegans group, unsure as to which.

Not helpful I ...

L91 is a member of the leporocanthicus family.

This fish is looking firm favourite at the moment.

Thanks Jools!!

I assume then that there are no others except in this genus?

Aside from L007 L.galaxius, are there any other plecs which exhibit the elongated teeth or is it peculiar to this species?

Reason being, my missus' Galaxy Plec died after a battle with my red-tailed plec!! I would like to replace it but can find no L007 around me or on the net. She doesn't mind ...

There's a sterbae in there too!!

Looks like c. delphax or c. brevirostris to me.

Can't be c melanistius as there are no caudal markings on melanistius and there are on your fish.

I most definitely concur!!

It's the red cross again!!

That was my initial thought, but looking through the Aqualog catalogue, I decided no as there always seems to be some element of black on the dorsal and a less coloured face than this one.

Spotted this amongst a batch of melanistius. Is this a variant of c schwartzi or maybe a c. agassizii variant?
This fish has extra long barbels!!
The best match I've found from the Aqualog catalogue is 'Corydoras sp. "SPOTTED-LINE"' on page 46. Checking Ian's site ...

Semiaquilus are enormous fish, surely they can't be put under the same name as these aeneus variations?

I also think aeneus (black)

Got my big shipment of 2 brochis multiradiatus, 4 s. prionotus, 4 c. san juan (bilineatrus?), 8 c. pygmaeus, 3 tjuvenile sterbae and 1 c. melanotaenia from Trimar today!

Would like to check s. prionotus please! (Also c san juan if they come out of hiding!!

http://www.corydorasworld.com/gallery3 ...

Sorry don't know if I'm in the right place for this, but ...

Looking at the Trimar website, I saw c. pronotus for sale. They are not on Ian's CoryCats site and cannot find them anywhere.

What do they looik like?

I'm fairly sure that I have 2 females and one male, the bottom one is smaller and thinner than the other 2. It may be a younger one or a male. The larger ones are around 5cm from snout to caudal penduncle, so a bit of growing yet to do before they're breeding size!!

I bought on the basis that I've ...

Found 3 of these in a tank full of c. metae. I'm fairly sure on c. simulatus but I'm normally wrong!!

£4 each. Reasonable?
