2 foot driftwood snag habitat

Howzit, I was wondering if anyone can help me. I have an empty 2 foot tank that I am making into a driftwood snag habitat.

Unfortunately the only fish that I know of that lives in this habitat is Panaqu maccus and I am not sure if I will be able to find them anywhere? Does anybody know of other species (preferably catfish but doesn't have to be) that would prefer this habitat.

 

You have a pic of this habitat? Sounds interesting.

 

As in my tank? Nah its still empty. Probably set it up this weekend...maybe. Just want to plan my stock before hand.

Google does not really have images of this habitat but the tank will be almost filled with driftwood and substrate will be sand. I would like to put leaves on the substrate but I only plant indigenous stuff so I am not sure what will be safe and what won't be. No plants so it will be like the Rio Negro in a way.
