I think 1 of the draw backs with them is that they are slow to reach sexual maturity...like up to 3 yrs...most people get bored well before then, me included, but I am committed this time round lol...to buy a mature group would be very pricey...there was 8 on here recently for $275 @ 3-4" if I remember correctly...a reasonable price but prob still at least a yr or 2 away from breeding size...
