There was the Crony that I think never went anywhere. I can't remember the member's name but I think he was a design student or apprentice machinist or something. I don't think it looked much like a fish though.
Custom maker Brian Flud was here for a while and his P38.5 tool had a fishy shape to it.
Also there's the Superior Titanium Shark tool, but I think I'm the only one with one of those.
I hope this helps!
