Sorry, not picked up on your e-mail, have been in Canada for the past week.

This looks similar to C151 from the Rio Tapajos.

Ian

Do you have catch location and standard length details, these would be good to compare with existing know species from the same location and if it is new then it will be allocated with a new CW Number.

Would appreciate details in e-mail or pm.

Ian

It Might be C. cruziensis, but I would need to have an idea where it was collected and what the standard length is.

Ian

First off you need to keep them on the warm side, say around 27-28C. Then it is a case of getting them into tip top condition before attempting any spawning triggers. The chances are when they are in condition they will spawn without anything other than a normal water change.

Ian

Without know its catching location I would say that the fish shown is C142, it has the same colour pattern as C. melanisteus, but the latter is a slightly larger species, which also has a longer snout.

Ian

The two long snouted species are at this moment in time unknown, Going by the head and snout shape, I do not believe they are C. septentrionalisit, There is a possiblility they are C. cortesi. The fish at the back look like C. napoensis.

Ian

Personally I doubt that they would ever cross, provided that there are enough of both sexes in the groups of the three species. Ian

If you haven't booked your place at the the best Catfish event of the year, then you need to get a move on.

There will be no problems for day visitors, but if you want to stay for the full package there are very few rooms left so don't delay book your place today.

Ian

Kampher, I am afraid Racoll is not right, if you look at the true Corydoras retculatus the body pattern is bolder and is dark brown and has a mat appearance, Corydoras sodalis has a dark silvery pattern that is finer. CW061 is very similar to Corydoras sodalis , but carries the black blotch in the d...

For those members or guests that were going to attend the CSG's AGM.

Because of the sudden severe weather conditions, the CSG's AGM has been cancelled and re-scheduled for the 3rd of February.

Ian

My best shot would be:-

C. agassizii
C. schwartzi
C. sp. C133

Ian

Before we can actually see if we are dealing with species crossing we need to determine the true identity of the species involved. The so called 'aeneus' group is a very confusing one, and many may be proven to be just regional colour form and I think it will take science a long time to sort them ou...

Just in case you may forget, I thought it best to bump this back up.

Places are going quite fast so if you are thinking about coming and to avoid disappointment book early.

Ian

I would also go with C. leucomelas.

Ian

The fish is

Exporters are using the name as a way to sell the species. They often call the 'Agassizii/sodalis.

Ian

The species known as C. pulcher Var II has been given the code CW028. The colour pattern compared the C. pulcher is actually quite different. There will also be variability within a population, but there are many who separate the variants and put their own names to them, to me this only causes confu...

It is with a very heavy heart that I report the passing of Alan Vaissiere he will be sadly missed by a very large number of aquarists, especially here in the Uk, not only for his like of a tipple or two and his ability to create many a lively debate about his beloved fishes. He will probably be reme...

Most of my breeding groups of Cory's are in tanks that measure 18"long x 12" wide x 10" high. These are mostly in groups of 6 or 7. Personally I would say that your tank is easily capable of housing a dozen of either of your preferred specie, but the stocking levels of your other fish...

There are a number od species that fall into what we affectionately call the 'Elegans group" and what you have I would say are C. bilineatus http://corydorasworld.com/var/news/storage/images/corydoras/b/corydoras_bilineatus/1165-3-eng-GB/corydoras_bilineatus_species_large.jpg Image courtesy Ian...

Definitely females, but which species I could not say. Possibly S. barbatus but both S. kronei and C112 females look almost identical.

Ian

There is a log of ground to cover with this post. The question about the depth of water, this is something I have never come across in 40 years of Cory keeping and breeding and I would be interested to know where or who the idea came from. The species mentioned would not have any problem reaching th...

There has been a slight change in speaker line up for the CSG 2013 convention. Due to an irresistible work opportunity Hans-Georg Evers has had to withdraw. However all is still good as our good friend Ingo Seidel has agreed to step in and take his place with two brand new talks. Ian http://www.catf...

One thing to remember with all fish is their patterns will vary from one to another, with some species it may be minimal and far greater variation in others.

And the head shap is also right.

I would still say C. ephippifer.

Ian

I met him many times on my visits to Norway, he was a very generous and humorous man.

Rest in Peace my friend

Ian

I got this species from state of Amapa, Brazil as the fish importer mentioned, but I have been researched all over from the internet and also from the books, those Corydoras species that I have, does NOT look like any Corydoras from that area. I would say my guess was spot on and you fish are C. ep...

It would be really great if you can make it.

Ian

With such total negativity I am at a loss as to why you actually posted in the first place. I put a lot of time and effort organising this event and I even organise pick-ups for traveling delegates that make the effort to come from a lot farther than the Isle of Arran. Still if you are so bored with...

For 100 C. pygmaeus or C. hastatus I would use a 70 to 80ltr tank.

Ian

In my opinion they are totally different and as Kim says they come from the opposite side of the River Amazon and from totally different water systems. If you are just looking at the colour patterns then there are several that are actually closer to C143 than C. amandajanea. C. ephippifer and C mela...
