Sorry to "hijack a bit" but here in Calgary pink cons aren't popular, they don't have any in the stores here, only black cons, and I guess a breeder have one petsmart some marble fry. I know the marbles are worth more, but could I charge more for pink vs black cons?
People won't care what their diet has been. You would be lucky to get no more than $20 for everything your trying to sell. I breed and sell marbled cons and I sold my 1.5"+ juvies (about 15-20 of them) for $20. I should've charged more but I needed the space.
