I'm very glad to say that the flowerhorn phenomenon has largely petered out in Singapore (and it seems in Malaysia too, and hopefully Indonesia and Thailand etc... as well)...... when you have a species that breeds like rabbits but "commands" arowana/show discus prices, you are going to get a spectacular crash (dozens of wannabe LFS specialising in flowerhorns in Singapore have gone kaput, and good riddance!)..... for myself, the aesthetics and ethics aside, I had been campaigning locally (on Singapore forums, newspaper letters and intercepting public talks) on the hideous environmental impact of released flowerhorns in local waters and am only too glad to see the end of this monstrosity (the fad as well as the fish).
