I don't mean to dig up old bones but I found this thread after searching "pangasius"...
I am a member of **************.com and I have posted the story there of rescueing a 7 year old, severly stunted Pangasius Hypalthmus. His name is Jaws, and he's very special to me. Unfortunately I will not be able to house him properly. I see you live in IA, that's a problem, I live in NY.
Would you be willing to take him? Shipping would probably be pretty high, but he's only 10". A very peaceful and special fish, I would miss him dearly but unfortunately I cannot house him. Let me know.
