hmm, I don't understand.
They are forced to add volumetric water!
How will they deal with the marine reptiles in this case?
And I imagine that marine reptiles will necessarily have the right to free prey that they can chase in their tanks, whatever the case, the fish could operate on the same principle as these same marine reptiles.
Well, I think, and this is just a guess on my part, that the Aquatics center housing the Marine Reptiles will function like the Aviary did in JWE, with the ability to add on "wings". I fear that the Marine Reptiles will not exist outside thier enclosure, same as the Pteranodons in JWE. We also will not have to feed them as that will be handled like the old Aviairy.
This would explain the lack of information, images, SFG, or FF on anything to do with Aquatics. Volumetric water is required in the environment to do this and it's 99% unlikely to be available this go. Just remember it took a new game to get the Pterosaurs to exist outside and interacting with the park environment.
