Oh you mean culls,
I'm not sure whether they (BM gang) has culls to sell to you. I don't have though because my original collection was wiped out by whitespot outbreak. Darn... I am now salvaging from the cull tank too.
Eeer RM10/pair is already normal standards for harder to get strains. Believe me when I say the guppies any of us offer are not quite near competition grade/show class yet. Those fishes will easily set you back for a full grown discus.

which I can't afford too for now.
