Hey mate totally depends on what someone is willing to pay.. As a rough idea for you here is what I've paid previously
Sizes approximate:
32cm sailfin - $100
18cm albino - $60
15cm albino - $50
2x 20cm gold spots - $150 for both
25cm gold spot - $100
From what I've noticed they get cheaper as they get bigger.. don't understand exactly how that works but I don't complain as I prefer big ones lol think its more got to do with the demand not being as great for larger ones though as my sailfin got to almost 2 foot long when it was vertical on front glass it's head would be at surface and tail touching sand on bottom was a great fish to watch swim especially under moon lighting
but I'd say my 6x2x2 would be minimum size tank for it
