All my girls have been under $4.00, with the exception of my 4 new aquabid girls. The four were $15.00, $10.00, $10.00 and free - and then the shipping on top of that. I got four healthy baby girls, though, very pretty, all f1 from Thai stock, all HF - a marble, two red dragons and a cellophane dal.
The females are generally cheaper... some males on aquabid go for upwards of $35.00... I look at their pictures and sigh, they are so pretty. But I'm hooked on the females. :)
