No person shall import, export, own, possess, acquire or dispose of
live piranha fish (Serrasalmus, Rooseveltiella or Pyrocentrus), grass
carp (Ctenopharyngodon idella) or hybrid grass carp within the state
without a license or permit issued at the discretion of the department
for scientific, biological or exhibition purposes.
it would be very irresponsible for those vendors to sell and ship fish to your state and i'm 100% they won't do it, their to established and well known to risk selling you fish without you haveing a permit, if you can give proof of permit they may still sell to you. though i have heard of a case where a less well known vendor did sell to a person in an illegal state and he got caught and was fined BIG time.
