Hardly. Tropical fish don't survive long even in Florida. Temperate &
sub-tropical fish are the real problem. Koi are far more of a threat
than tropicals.

It is a well known fact that tilapia have create a huge problem in South
Florida. They are surviving in the wild there, and have been displacing
native species of both fish and vegetation.

That's because Tilapia are a sub-tropical species, and Florida is just like
home for them. _Tropicals_ wouldn't be a problem in Florida. However, you
didn't bother to read what the OP said - he's in SE Asia, where it _is_
tropical, so it's still an issue, but no more so than escaped koi in
temperate climes.
