C. pavanelliae is a lineage 8 sub clade 4 (straight snouted) species

Certainly a water problem, I am certain it is nothing parasitic, but bacteria will infect damaged areas. The first thing I would do is make a large water change 75% and then add a full dose of API Melafix. The red blotching under the scutes is hemorrhaging most likely caused by nitrite burn. Quite o...

Looking at the tank statistics I think the main problem is that the water is very soft and your nitrates are up a little, and it is the presence of nitrates that is probably causing the problem. The first thing I would do is a 50% water change and then reduce the amount of food. With very soft water...

C. leucomelas.

In just under a year from now Corydorasworld will be hosting a "Cory-Vention" The date is fixed, the Speakers are booked and the venue secured. This event hosted by Corydorasworld.com promises to be the largest coming together of Corydoradinae scientists and hobbyists ever held anywhere on...

All packed and ready to head out to south eastern Peru and the fishes of the Madre de Dios drainage.
Primarily we will be looking for Corys and Loricariids, especially want to see what Loricarids can be found above 1000 meters.

The look like young C. sp C126 but time will tell.

The look to be juveniles of one of the 'elegans' group species, many of the developing young have a pattern like this. What size are they SAL. (Body length).

This fish looks very much like CW026, reportedly coming from Venezuela, but the exact location is not known. For the record the genus name is Corydoras not Corydora. It is the same for multiple or single fish. Image courtesy Ian Fuller & Corydorasworld.com http://www.corydorasworld.com/img/galle...

Firstly the original CW014 Red stripe (Not a laser sp) and CW023 Orange stripe (Not a laser sp), were two different groups of fish purchased a different times but from the same store (pier Aquatics) The CW014 "red stripe" had a very red stripe, which was enhanced by the black base of the t...

For those attending if you have catfish you wish to sell, there will also be a number of sales tanks available for hire, but these will need to be booked well in advance to ensure availability. contact chairman@catfish study group.org for details. Just a little reminder for all would be CSG conventi...

Also the species called "Deckeri" is known under the C-code C003 and is closely related to C. axeldodi and CW021.

For those that are undecided, this is what you get in the weekend package. Two nights (Friday & Saturday) B&B in a 4 Star accommodation plus a 3 course dinner on each evening. The convention 2 day ticket will enable you to attend all 11 lectures from 9 top class speakers, and if you have nev...

I think for you to get a the true colors of the fish to show you need to keep them over a natural tan colored substrate. Black substrate will always make your fish go dark.

In my opinion the fish in the picture are albino C. zygatus, most if not all albino fish will show the type colour pattern as in the effect of brushed velvet.
I can clearly see all the pattern characters of C. zygatus in these fish.

Personally I think thr RA picture is C. atropersonatus I have posted an image of all 4 species. The spotting in both C. atropersonatus and C97 are similar well defined rounded well spaced spots, in C. sychri and C53 the marking are more like small irregular blotches and tend to be more compacted. Ia...

They are both the same species, CW014 was determined on specimens that had been kept over black substrate, which darkened the fish giving them a red stripe. Over normal lighter substrate the stripe is orange. These are not the same and should not be confused with CW010 the 'Gold laser'
