Once again you have stated this incorrect information.
Here is an (incomplete) list of freshwater puffers.
Please note that all of these puffers live in freshwater for their entire lifecycle, never venturing into brackish or saltwater and although salt tollerant, should not be kept in a brackish or marine tank.:
The true freshwater puffers are:
fahakas, dragons, congo, stanley pool, mbu, red-brown, leopard, golden, greenbottle,
remotus, Bornean redeye, dwarf imitator, redtailed redeye, crested, striped redeye, bluespot,
silius, bailey's, abe's, fang's, emerald, kretam, eyespot, pignose, sabha, brown, waander's and assel puffers
