All Indo, NTT, and Pulcher are wild caught.
NTT will be the next fish to become really scares out of NTT and Indo. Mainly because of where they're all caught, which is The Mekong in the north east of Thailand.
The river in that area is drying up quicker than usual in summer because of the Dams up river in China. In addition to this I only every see 2 or 3 inch fish for sale, so where are the big ones? Eaten would be my guess, the same as the ST in Thailand.
I'm also no expert on Dats. I own 3 NTTs. Never owned and indo or a pulcher. I got interested in the subject because I asked the question about captive bred indos on here. I saw thousands of tiny indos for sale in Bangkok. The were being sold in plastic bags on the side walk near Chatuckak market. Vendors were telling me captive bred, but I could find no evidence of it at all. I visited big fish farms here and saw nothing. I also visited a university to talk to the staff in the Faculty of Fisheries about the ST breeding programme in Thailand and to get their thoughts on Indo breeding, and I spoke to a member of staff at the Department of Fisheries on the same subject. I'm 100% certain Dats are not farm Bred, especially pulchers.
As for the small ones that keep being shown. I reckon some of them are real, but the vast majority are not pulcher. I've been told by 2 separate catchers and sellers of NTT to steer well clear of them, and any that are found in Bangkok's Chatuchak market are not the real thing. These guys were catching ST in Thailand years ago, they know what they're talking about and have the contacts in JJ market to get you what ever you want.
About 5 months after seeing all the baby indos in plastic bags I was offered "st" in Chatuchak market. I challenged the seller and said that it wasn't ST, but indo. He asked me how can i tell the difference, it looks the same. It was only 400BHT, compared to the normal 200BHT for regular indo.
For me there are too many clues pointing in the same direction. I might be wrong but that's my own feelings.
