Usually people on this forum use DT for delta, and Dbt or similar abbreviations for Doubletail.
Well yesterday, after searching through some older threads for interesting dicussions, I came across someone who said they had a DTHM fish. Someone else responded "How is it a delta and a halfmoon? It can't be both."
The original poster responded that usually on fish forums, Dt is Doubletail, not Delta. Delta is usually abbreviated Del or something like that.
So do we use DT or Dbt for Doubletail? Dt or Del for Delta? Was the person on that thread who thought DTHM meant delta halfmoon just confused or mistaken? Or is DT=Delta correct for this forum?
