I think the Image in the cat-elog is C. delphax

For those that are interested, on the 20th September the Catfish Study Group will be holding it's annual Open Show and Auction. There will be many rare and unusual Corys on display in the 5 Corydoradinae classes as well as Breeders and Pairs. The auction will undoubtedly has several lots containing ...

Not C. schwartzi. this species has a black blotch at the base of the first two or three dorsal rays, this colour extends up into the first two soft rays. the dorsal spine is grey. Your fish looks closer to C133 although it does not look in the best of health.

We are now ready at GoWildPeru to provide your personalised fish collecting experience. We are based in Puerto Maldonado in the Madre de Dios region of south eastern Peru close to the Bolivian border. This is a very bio diverse region, with fish collecting possible pretty much all year round. We hav...

I knew of one specimen of C. aeneus, a female that was 42 when it died. I also had a breeding group of C. sterbai that were more than 20 years old when I retired them of to a display tank in the shop where I used to work, that was 2 years ago and they are still there doing just fine.

The trouble is most people treat all Cory species as coming from the same water type and conditions, but I am afraid they "Don't". Far from it, so before deciding what you think they require, a little research into where they came from. I am talking wild imported, not farm raise fish here....

We all tend to overfeed our fish. In nature there are times of the year when the food supply is very limited if not nonexistent and in some regions this can be for several weeks. Decreasing water levels and dwindling food supplies is a process that takes place annually, in these areas the fish numbe...

With just over four weeks to go all our room allocations are now taken, but there are plenty of 1 or 2 day, day-tickets available. We would have liked to have had a few of you US guys make the hop over the pond though. We will undoubtedly be rubbing it in after the event, with tails of the fantastic...

Once they are mature, CW051's are fairly easy to sex via the body shape when viewed from above, otherwise check the ventral fins, males are more elongated and pointed, the females are fan shaped. Breeding this species is not an easy task, I think to date I am the only to successful breed and raise t...

Collecting fish in the Amazon is a fantastic experience and one I can thoroughly recommend. But! make sure you go with the right company/person. Not all have you or the fish you collect at the top of their "To be looked after" priority list. Check out their credentials first. Margarita Tou...

This is probably a new species. The vast distance between the type locality of C. bifasciatus and Leticia is one thing but the actual pattern is different, in C. bifasciatus the lower band runs along the intersection of the body scutes. Your fish shows the typical C. parallelus pattern, but with a s...

I would like to see more images of the long snouted one, the image looks a little washed out.

A quick update for those that are hovering over their decision to attend the CSG's 2015 convention, as of mid day today 5th December we have already taken up just over a third or our room allocation, and would advise any potential guests from outside the UK to book their place as soon as possible to...

The booking forms and menu choices are now on line at http://www.catfishstudygroup.org/core/convention_2015.htm Early indications are showing that we are heading for a record attendance, which means we will in all probability use up all of our room allocation. We can house 300 delegates but the hote...

We are just about all set for the CSG's 36th annual convention, so to ensure you don't miss out it is time to make your booking. Forms can be found at: http://www.catfishstudygroup.org/core/c ... n_2015.htm

I would say it is closer to .

There is one feature that I pointed out earlier in the thread, which is that the fish we are calling C. venezuelanus and the LLanos fish both have grey caudal fins and the C. schultzii and its black strain have reddish caudal fins. I think a chat over a couple of beers at the (AACC) Cat Con should s...

Just my 2 penny worth and bringing the topic back to the title "corydoras & gravel/sand" There are many natural area where Corys are found over gravel, but this is not rough like road chip pings but smooth pebble like. The size can and does vary from 1 to 2 millimetres to large boulder...

Shane, Jools, To pin another CW number on yet another "aeneus" type I have to be 100% certain that all the evidence is accurate especially when the the division is with fish from what is globally the same region. There are a number of 'aeneus' types already listed in my 'aeneus' group page...

Jools, We seen to have introduced C. scwartzi into the mix, I think the (Corydoras venezuelas sp. "schwarz") shop listing is a typo by the store keeper. we are talking C. sp schultzei, which is the parent species of the commercially "Black" Cory. I would like to add the C. sp. ae...

The dark one I titled C. venezuelanus Black is one of the images you sent me for comparison and I assumed it was one of the fish you or Shane originally collected. It looks to be identical to the Llanos fish. The ones captioned C. venezuelanus are f1's from my original wild fish bred in January 1999...

There are many many Corys that live over a layer of leaf litter. This will include any of the fish from the tributaries of the Rio Negro. Generally if the water is moving relatively slowly then there is likely to be leaf litter or other organic material. It is the tannins from such organic material ...

I have been looking into this problem for quite a while and for what they are worth, here are my thoughts. Firstly I am one along with other Cory specialists consider that both C. schultzei and C. venezuelanus to be valid species, which is what they were first described as, it was in the late 70's e...

This is just a little niggle of mine.

More and more people are referring to their Corydoras, and Aspidoras as Corydora and Aspidora.
Corydoras and Aspidoras is the same spelling for a single specimen as it is for a hundred.

You need to tack some profile images then we will have a better idea.

Ian

There are only 2 lasers, "Green" CW009 and "Gold" CW010, The other one that is referred to as a laser, CW014/CW023 (Same species), is not a laser but referred to as Red/Orange "Stripe".

Algae wafers are not suitable for Corys, they are omnivores and require a variety of small foods.

Feeding beef heart to the Discus is fine but like algae not good for Corys.

Ian

C. sterbai, would be a good choice regarding temperature, but the one problem that can occur is with the diet. Basically the high protein foods made for Discus are far too protein rich for Corys, and will eventually cause problems. The only way to combat this is to have a good supply of live foods l...

I would also go with C. delphax.
