Did he have invasive species? I don’t know the laws but I just assume they are stricter on export than importI thought you needed a permit to bring fish into Hawaii? Idk how hard it is to obtain. Just that a friend could not bring theirs with when they moved there due to laws. They probably worry someone might bright a nonnative fish or pet and release it. Hawaii is pretty strict about things. Last I checked, I can’t even move there and bring my domestic bengal cat.
