Best Cory For My Altum Tank

[cockroach]

My new tank is now set up and my altums arrive on Friday. I have also placed an order for 20 'jumbo' cardinal tetras for my 75 gal. I want some Cory's in there but would like to keep it a species from either the Rio Negro or Orinoco River system that naturally occurs with the altums. It needs to be able to handle the temp of 30C year round.

So far I have looked at:
C. parallelus
C. adolfoi
C. rabauti
C. duplicareus
C. serratus
C. robinae

Are these good choices. I really like the Adolf's.

Thanks in advance.

Bump. Anyone?

I understand sterbai and leucomelas can handle warm water.

Yeah I know about the sterbai's but am really looking for a cory from one of those 2 rivers that can handle the heat (so to speak).

Thanks for the reply.
