Just got a reply from my fish shop friend -- he has this Channa Barca at his shop in Bangkok; price he initially offered was 55,000 Thb (~US $1,760 -- about $200-400 more than I paid for each of my 2 Malaysian Gold Xback Aros, and about the same price as a high quality 10"-11" Super Red), though I reckon it could be negotiated down somewhat. But again personally not really interested, awesome as the fish is.
Esp. at this price it suggests even more that captive breeding efforts have been successful at least to some degree, so perhaps we'll see more and more on the market in not too distant future (and it would be a positive example of how the aquarium hobby can help save some species from possible extinction).
