CB = Captive Bred (parents may be wild caught or unknown but were bred in captivity)
CBB = Captive Born and Bred (parents were CB or CBB and bred in captivity)
LTC = Long Term Captive (wild caught but has been in captivity "long term" -- opinions differ as to what constitutes "long term" but in general should mean at least one year in captivity and feeding)
WC = Wild Caught
FH/CH = Farm Hatched/Captive Hatched (mother was removed from wild gravid and held in captivity either long enough to lay her eggs or long enough to hatch them, then released)

HTH! (Hope this helps!)
