Right now our four piscavores (Spinosaurus, Spinoraptor, Baryonyx, and Suchomimus) have fish feeders but they find them equally as good carnivore and live bait feeders. They should get a bonus for eating fish. Or, better yet a building could be made that clones specific prehistoric fish that they ate. For instance, Spinosaurus was known to eat Onchopristis. Also we need more piscavores. We have barely any.
