The Threadfin Butterfly body would accomodate other similar butterflies like the Facula, Farfalla, and maybe Raccoon.
The Blue Chromis body would accomodate a Green Chromis or Blue Damsel.
The Koran Angel body would accomodate a juvenile Emperor Angel.
The French Angel body would accomodate an Annularis or Asfur Angel.
The Percula Clown (Occularis) would accomodate a true Percula Clown, maybe a Tomato Clown, and possibly a small Sweet Lips Clown.
The Queen Angel could accomodate a Bicolor, Coral Beauty, or Rock Beauty Angel.
The Addis Butterfly could accomodate a Pakistani or Pearlscale Butterfly.
The Purple Tang could accomodate a Chevron Tang and maybe a Red Sea Tang if much of the top fin is ignored.
The Lionfish could accomodate a Panther Grouper if the side and top quills are ignored.
I'm sure there are others. Of course whenever I mention helping Jim with any of the skins, the ground starts quaking and I hear a thunderous voice.
