Amusing thread, and the personal slagging off is great!
Ok, can someone explain to me why an ST, if it swims a few miles (in very simplified terms), suddenly becomes a different species? I understand if it maybe cross breeds with an IT or gets stuck in a certain area where evolution is given an opportunity then there will of course be regional variations and that fish may well become a sub-species, perhaps something such as Datnioides pulcher sp. Cambodia? This is something predominant in the snakeheads Channidae, there are so many variations of the Channa gachua, as an example, but they are still all Channa gachua.
back to Datnioides, visually there is definitely a difference between CT, IT, NTT and AT and in many ways, behaviour differences. I suspect they are genuinely different species which have established themselves over countless generations. However, I see no reason why a number of ST's could not have:
been forced to find another area due to something like pollution in their particular stretch of river
relocated due to perhaps work on areas of the river
relocated due to drought
Decided they didn't like it where they were
I really don't know, I'm only guessing here but surely this could have happened? Surely in all that space there are a few love-struck couples of fish of the same origins?
Or could the CT/ST variations be due to ST/IT cross breeding. Or maybe too much in-breeding? Many of the 3 bar Indo's that we are seeing certainly have many of the looks of an IT but, in my experience, behaves nothing at all like an ST.
I really have no idea at all, but for myself I hadn't noticed my passport change to "Homo sapien sp. out of normal territory" when I go on holiday so wasn't sure why the rule applied to fish?
For what it's worth, I'd have some of those 3 bars if I found some here in UK.
I know, let's finalise this debate. Each and every one of us with a Datnioides species submit one of them to science to get a definitive set of taxonomic results.
Or maybe I'll just enjoy the fish I have which I buy because I like the look of them.
