About 2 months ago, I had 3 spawns from the bronze cory. Unfortunately I lost almost all the eggs as I did not operate my tumbler well. Since that time I have not changed the conditioning nor the water changes but they have not spawned again. Another cory species in the same tank is now in its 4th s...

Thanks for the answers, especially Eric! I know now that it should be a different species then as all eggs have been hatching and it is already the 3rd batch now with these smaller eggs. Fry also seem to behave differently as they seem to be 'grazing' more on the sides of the tub I am using to feed ...

In the same tank I keep aeneus, habrosus, similis and CW008. About 2 months ago, the aeneus were spawning profusely on the front glass of the tank. The last 2 weeks I have been coming home to smaller eggs that were laid on an Amazon sword leaf right in front of the outlet. I expected it to be a diff...

So nothing more hatched; I have 4 fry from 40+ eggs; a very low hatching rate.

Last night the number of eggs had diminished greatly; I am down to about 12. As most were scattered and not clumped together, I can only conclude the eggs were eaten before fungusing.

On a more positive note: there are 4 wrigglers today.

Thanks for the tips and info!

Oak leaves galore!
So, if I understand it right, these fish prefer warmer water for spawning contrary to the species that are triggered by colder water?

Danke Daniel!
Do you happen to know whether they are floating spawning mop spawners or more substrate spawners aka in java moss or similar?

Yesterday I scored some CW008 aka gold striped elegans in a local shop. Unfortunately I have not been able to find much info on this cory.

Anybody that bred this species? I would love to hear your experiences!

A few weeks ago I got a Cobalt Aquatics Egg tumbler at an auction. Two days ago I had an opportunity to use it again with C. aeneus. As my last batch in the egg tumbler fungused completely (my fault; the air setting was too high), I decided not to take any chances and put some ramshorns in with some...

Thanks Karsten, on another forum we were also concluding it would be delphax. This also coincides with the origin as this cory is native to Columbia. What I meant with mature is that they are ready to reproduce and as you say, at that point the colour pattern and other physical distinguishing featur...

Goedenavond landgenoot!

If you click on the map that comes with the profile you can see they can be found on the border between Venezuela and Columbia (Orinoco basin) so I would say it is a possibility.

Could this be brevirostris? The snout is pretty long. They are definitively mature as they measure about 5 cms from head to tail.

I love going to the Mexican fish (import) market because a lot of their fish comes from Columbia and this means inevitably corydoras during the season! they are mostly being sold under trade names (not scientific names) and most of the time they have no clue what they are selling. This has its own c...

Ok, thanks for the replies guys!

I think you are right Silurus, and the habitat range is also correct as the County Luotian I found it in is part of the Yangtze river system.

On my last mission in Hubei province, Central China I had a chance to go fishing and found amongst others the following fish: http://i178.photobucket.com/albums/w244/Biulu/DSC07548.jpg http://i178.photobucket.com/albums/w244/Biulu/DSC07540.jpg http://i178.photobucket.com/albums/w244/Biulu/DSC07565.j...

Ok, thanks very much!

Thanks Ian! What makes you think it is a female? In all the pictures of females I saw, they have more black on their flanks than just the stripes, whereas the males seem to have the second stripe...

This could be, but a male then as it doesn't have any dots like females do.

If you click on the first picture it gets about 10 times bigger and yes, I can see the rays there as well...

This fish came in with a batch of c. arcuatus. The body is currently 2 cm and with the tail it would be almost 3. It is clearly a juvenile. Some people have suggested c. arcuatus but the body colour is much more pink than my real skunks, which are cream white. Plus what about the 'extra' stripe unde...

Lieber Karsten,

Thank you.
The fish is currently around 35 - 40 mm, so pretty big already. All corydoras we get are imported from Columbia and I do not know which ones are bred in captivity or which ones are wild caught.

Ok, I had a look again, but it is very difficult. Either he doesn't have the barbels forward or moves to the back of the tank.

If both have the 3rd barbel, then yes, it looks more like simulatus as mine doesn't have the black 'blotch' on the flank.

Thanks! I do not intend to obtain this species from a shop (I am almost certain I won't be able to get them....) but rather through my local aquarium society. I know they are not known to be bred in captivity, but they will be able to give me trusted sources for these fish. Good to know that a pair ...

Oh, and the Crossocheilus will eat your Java moss! Well, they did mine at least. Thanks for all the info! I am not too hung up on java moss so that is not a problem... I just found Crossocheilus atrilimes, a smaller species that gets only to 7 - 7.5 cm; that would be ideal! I prefer to keep the fis...

I considered the siamensis, but I think it gets too big and needs more current than I will have. I am also finding confusing info about these fish. Some say that the siamensis is never seen in the trade and that most are oblongus which get to 10 cms although others say 16 as well. Then I read they s...

Hi everybody! I am setting up a new tank (125 litre) with a Asian white water theme. Temperature is going to be 24, pH around 7.4, low current, low light, dark substrate, heavily planted. Future inhabitans will be: zebra loaches peacock gobies cherry barbs lambchop rasboras female betta Plants: Cryp...

Ok, it doesn't have the 3rd barbel so it must be septentrionalis. Thanks, Dark One!

Yes, you are right. I guess what I need to do is to see whether my cory has this 3rd rictal barbel. I will get the magnifying glass out! I have another unidentified cory, which shows similarities to the septentrionalis. It would be great if it turns out that I have 2 of the same type, instead of 2 l...

Hi guys, I found this lonely cory at the fish import market from Mexico city the other day (imports from Columbia). I have been going through all the profiles here but have not been successful. The fish is currently around 3 cms. http://i178.photobucket.com/albums/w244/Biulu/DSC08143.jpg Can anybody...
