Nice fish!!
I have learned how to keep them the hard way....
Temperature should be 20 - 22 C degrees.
Some rocks in the tank and strong and fully oxigentaed water will be good.
We fed them with chopped tubifex and with reasonable success.
In my case I had several specimens sharing the same tank with ...

Well, I ve had lot of corys for my job...

Hallo Steve, Marc
Thanks for your info.
So the name would be Tatia intermedia sp.

I usually keep them separated from others and feed them with tubifex, so I dont know if this is a good idea to keep them in a ...

Hi Jools... you mean Marc and Steve or the Novias ....?

I have to put big PVC pipes (pieces) in the tanks so each one will fit in.
Then they come out during the night and feed with any thing they find in their way (small mp3 included...)

If there is no food enough, they probably kill each other ...

Hi Marc and Steve

Thanks very much Ian.
Corys with that "hump" are not common
Only Armatus I think...
Here's a photo of another humped cory, this time an Armatus...

I just got this today.
