ID: What Cory is this? - Corydoras gracilis

[yorky]

Hi,
I saw this small as in 3-4cm sized Cory in An Aquarium (Tokyo, Japan)... not sure what it is..
But it looks very nice!

Corydoras gracilis.

Only seen in Singapore once in the last 3 years, although much more frequently in North Asia. A rare species for some local collectior, but challenging to keep alive.

Cheers,

[yorky]

thanks. why so? cold temperature requirements?

i had kept this cory for 2 times....they never live pass 6mths...
besides hard to breed, also hard to rear...a big challenge

Finally lay my hand again 3rd time on these rare ones this week at R.O.C.
The whole wild shipment only 16pcs, unlike other Corydoras species that i observed at the wholesaler tanks usually hold between 100+~500+pieces per shipment.
i manage to book and brought up a batch of 6pcs before they end up to Japan again.
i will post of their picture soon

Hi all,
So far, none has come up with a reason why these Corydoras gracilis are so tough to keep alive and breed. Temp? Live foods? Water or what?

Joe, good luck and we'll be looking forward to updates!

Heard they need low temps... ie around 20C

They were distrubuted in Europe 2-3 years ago from a breeder in Germany and I was lucky to get 6 small F1s.

I keep C. gracilis and actually find them to be very easy. As long as you keep them no higher than 21-22 degrees celsius and in soft water (I use 100% rainwater). A thin layer of sand, some bogwood, a good handfull of oak leaves and some javamoss. They don't predate on eggs or fry so they can be kept as a colony that just keep growing

BUT moving them can be tricky as they are very sensitive to changes in pH etc. I once killed 50+ youngsters by mistaking the buckets with tapwater and rainwater during a waterchange...

Revisiting my quest for the elusive C. gracilis after 7 years. Please sound the siren of any sightings or leads. I need to get off this plateau and be challenged. Many thanks in advance!!!
