The smallest you will find is 6" in total length for red pikes (johanna, atabapo 1, atabapo 2, tapajos 1 & 2). They are seasonal and size will vary vendor to vendor. Orange pikes are no longer exported from brazil.
at sizes that smal 2-3", many vendors aren't able to identify wild caught juveniles from lugubris correctly. There's still a lot of mislabelling between sp Venezuela and strigata.
