This is the second Bob I’m arapaima fishing with in Thailand. Both Bob hails from Australia. Some things are funny like that.
This trip, by the way, happened in May 2015.
Amazonbkk is still the place for arapaima in Thailand (probably the region) as they have a healthy population of fish stocked and some of them are huge, real monsters with the largest exceeding 100kg or over 200 pounds!
However, like many catch and release ponds the fish gets more difficult to fool with each visit.
