Hi I also figured out that from two each of your "true types" I can find all of the other fins or bodies in 4 or 5 generations... My first generation is different twinfin+silky=golden or Spotanus+Shark=Goldbulb, but starting with the second generation, I can also produce all fins and all bodies. (I may look to see if I find another alter 3rd true type that might give better results...)

I've also raised all of a certain body type (I've already done fruitfish and fatfish.) in my quest for finding a complete set, but didn't take pictures. I am taking pictures of the "perfect fish": spined stickfish, etc. Imay start another thread to get opinions on what they all are.
