umm.. just thought I'd give my two cents.
Flower horns were a craze here in Malaysia around 5 years back. Suddenly everyone wanted one, and the price for a 'good' FH could go up to the thousands of Ringgit. Many characteristics were looked into, like the 'bump' on the head of the FH. The bigger, the better. Fish shops that sell only FH were mushrooming.
Me and my friends too were caught in the fever, and added tanks to our houses like nobody's business lol.
I even succeded in breeding a few fry, and the most expensive FH i bought was RM 50 (USD 13?). As I was still a high school student back then, I could not afford to buy expensive ones.
But now, all those FH fish shops have closed business. Nobody wants to keep a FH anymore. Myself included; gave all mine away 3 years ago.
It is rare to see a FH now in a lfs, and now the 'good' ones that could catch thousands of ringgits back then are being sold for just hundreds. I guess the same can be said for neighbouring countries like Singapore but i might be wrong here.
It's kind of sad and depressing for all those FH bought and bred by people during that time. Most of them are unwanted now, and I can only guess what happened to them.
It's just my thoughts and insights though.
