That depends on some variables...
Availability, how often is species available? Demand for species?
Where are the fish coming from, local, regional, out of region/international?
Price per unit & shipping cost?
Mortality rates per shipment and does retailer get credit/compensated for dead fish...
IME/IMO, EBJD's are very fragile when young and mortality is high.
That said...
That price does seem a little high, atleast for my area, average $25.-30..
