1st thing to consider : Source
2nd thing to consider : Money $$$

Source : How do you find quality guppies in Malaysia? Do you think those LFS/Agent willing to import high value guppies into Malaysia?

Money $$$ : How many of us (those guppy kaki) able/willing to spend RM100++ for a pair of normal grade guppies? Do you think those show grade (value from RM300 up to RM1000) guppies can be accepted by those kaki?

And one more in my mind, who is qualify to judge what is so call "Quality" guppy in Malaysia?
