We keep them in closed systems and use a liability release to sell to restricted states...The customers must abide by their state laws. California is the only state to confiscate an order...the CaF&G officer told the customer she couod get the fish then confiscated them.. Ca recently made possesion of tilapia illegal in the northern part of the state....Except for Ca and Northern Florida, tilapia can be kept in closed systems without restriction, like any other aquarium Cichlid.
