I was interested in trying these guys out myself, so I sent my LFS an email enquiring as to availability... this is the reply I got:
"Cochus' blue tetras are a commonly available fish. Despite their beauty we do not normally carry nor recommend these fish, I have found them to be extremely aggressive & capable of harassing even considerably larger fish to death. If you do intend to have a go with them I can easily get them for you, but I would recommend you keep them in a species tank."
Yikes!
