So, with a little “insider knowledge” I would tentatively ID these as Aspidoras CW126. If you are interested in more, or would like to start fresh with correctly identified Aspidoras, please feel free to reach out. I keep CW126, Aspidoras raimundi, Aspidoras poecilus, Aspidoras fuscoguttatus, and al...

Pleco2381 where did you get these please? Not in Columbus OH by any chance? Thank you - Rob

Hey Jools, just my opinion, but this is C133. I have CW127 a very similar fish from the Tapajos basin. Within a single fish the background color and mask is quite variable depending on substrate, breeding condition, age and possibly even mood. Looking at this photo I feel the fish would fit well wit...

Really interested in the results if you can do that Eric, that would be super cool!!! C.sterbai - classic toxin producing Cory. Spook them in a small container and see if they lay on their side and produce a little toxin.

Just as a note, before I purchased my WC C.trilineatus from a reliable source (Jeff Michels of aquaticclarity.com) I attempted to purchase LFS "C.julii" which were indeed C.trilineatus 2 times. Both occasions the entire groups ended up dying within a few weeks. Their behavior before dying ...

24 hours! Sorry I didn't read thoroughly enough! Yes Agreed aggressive strain of flex(columnaris)!

That would be me - thanks for remembering! :) Yes, I don't feel that CW010 (orange lasers) which is an "aeneus type" and C.leopardus which is a "straight snouted" Corydoras will likely hybridize if kept in the same tank. Another important factor is group size. If you have groups ...

My suggestion is to grow them out a bit and post pictures of the more mature fish. I have young C.axelrodi right now and they display this pattern ... somewhat. The dorsal fins of my juveniles are not quite as dark as the ones in your photo, but that could be due to being photgraphed on a darker sub...

Next time hit them with a simultaneous treatment of kanamycin and Furan 2. Knocks out fin rot (which is bacterial) every time. I've done this on at least 5 occasions with 100% success rate. My C.wotroi even grew back her tail from what can only be described as a "nub". Come over and get my...

Looks like a baby "elegans type" Cory. Possibly C.napoensis or C126, but no promises on what kind it will turn out to be. Looks a bit like my C126 when I first got them as juveniles, and somewhat like the baby C.napoensis I raised for a friend, they are very similar fish as adults either w...

If folks haven't had a chance to read this please take a look! Luiz Tencatt is a close friend and has done an excellent job on this redescription. The original description was done using only 1 holotype and 2 live aquarium fish paratypes that were (presumably) not preserved and made available at any...

The "julii" your Petsmart gets are most likely Corydoras trilineatus - these would be fine as they don't get overly large and really won't bother small fish in your tank. They can look really nice if they are fed properly and kept in good water conditions as well. As bekateen stated Panda ...

One possibility is the little guy is getting too much protein- I can't get "novo baby" here in the US as far as I know, but if this is a really high protein food that could be the cause. I'd try to start some pre-soaked flake or small pieces of tetra tabimin sinking pellets to round out th...

In my opinion the pale one is C.ambiacus, in the same (top post) picture the other fish is C.trilineatus, and the fish in the 2nd picture (top post) is C.delphax. These are all fish that I have seen at Petco and they (all Petcos) are supplied by the same national fish supplier according to the Fish ...

Hi Biffa, I agree with Eric here in that you may have a large enough group now that eggs are getting eaten. I've had tanks of Corys where they breed once a week for a very long time, but if I leave fry in the tank while the adults don't eat the eggs the fry do. The adults may not consider the eggs a...

C.habrosus is fairly easy to find, somewhat easy to spawn, and does well in small tanks. My question to you is if you have a 75 gallon tank why are you looking for a "dwarf cory"? I would think something larger would be easier to find/see in a larger tank. A school of C.sterbai for example...

While researching Cope's 1872 papers that describe C.trilineatus, C.acutus, C.amphibelus, C.armatus, C.ambiacus and others I discovered that the Rio Ambiyacu is now known by the name "Rio Ampiyacu". For whatever reason Google does not show this river in their Google maps (street view) mode...

Just a matter of opinion here (I can't see the top of the fish in the picture so I can't say this with 100% certainty), but Karsten, is it possible the fish you believe to be CW008 could be C041? I have both of these sp. which are very similar, and to my eyes the line going across the top of the bod...

Hybridization can lead to sterile offspring(they may not be able to successfully mate). I don't know of any other issues, but there may be some. The real problem is that there is already such vast and amazing diversity in the Corydoras found in nature that creating tank raised hybrids creates furthe...

I kept somewhat large groups (7 C.melini and 8 C.panda) together for a while to grow out. I did not witness any spawning but when I pulled the C.panda out to put them in a separate tank to spawn I did find one baby C.panda. As far as I can tell there is no sign of any C.melini genes in this fish, bu...

That sounds like a great idea! Open discussions can be just as valuable as talks in my experience as long as they stay on topic. I had a great time at my first Catcon! Thanks to everyone who put together the event, the incredible speakers, and to everyone who attended. What an incredible group of pe...

More or less in that same tie, I came across an article on body size and heterozygoty in nature, it turned out the larger fish - juveniles - in a certain group were more heterozygote then the smaller ones. This being said - would it make sense with a limited population of a certain fish (i.e. chanc...

Hi Eric, the best resources I've found for researching C numbers and CW numbers are this website and Ian Fuller's CorydorasWorld.com . If you find reading paper material preferable to web reading - Ian Fuller and Hans Ever's books "Identifying Corydoradinae Catfish" and "Identifying C...

Hi Andrew, I'll be bringing a few S.barbatus juvies, some unknown Scleromystax juvies (hoping to get an ID before the convention- they were sold to me as S. kronei but I'm pretty sure they are not that), and some C.schultzei(Black). I have plenty of green lasers, C118, and CW052, and I have no inter...

Here's a link to a good thread explaining the difference between zygatus and rabauti. There's a picture of a C.rabauti fry in this thread which in my opinion looks really cool! Now if I could only get mine to breed! :) http://www.planetcatfish.com/forum/viewtopic.php?f=6&t=29100&p=186102&...

Based on some descriptions of C.ambiacus I've read (from seriouslyfishy.com if I remember right) - "the black stripe on the first few dorsal rays run half way up" I'd say that is another possibility besides C.agassizii for the "non-delphax" ones in the first picture, I do agree w...

Even if there aren't millions of "Florida Plecos" there are surely millions of eggs. If you haven't already take a look at this: http://www.planetcatfish.com/shanesworld/shanesworld.php?article_id=489 In my opinion the egg collecting better explains the extremely large number of small (I'm...

Thank you Karsten!

Thank you Thursty! Very cool look to those fish, I would have loved to see what else you pulled out of the Itaya! Did you go on an organized collecting trip? As far as the iridescent green color I find this interesting as to what causes it. I have heard of both diet and an organism causing a differe...

Karsten do you know why they are so Green? My wild caught C. acutus came in like this but it faded with time - it looked so cool which I could make it come back!

Cheers,

Rob
