Aquarium Expansion Pack

So, most of us are expecting some kind of aviary pack, and, I also would like one, but i think its way better to add an aquarium expansion pack. I mean, yeah, we got aquatic pack and wetlands animal pack, but it does not add true aquatic animals, just semi aquatic. So here is my idea.

So the pack would work like the marine packs on ZT and ZT2, and therefore, here are the changes other than the actual pack:
Changes to animals: All semi aquatic animals and aquatic animals will be dropped directly into the water, to aboid aquatic animals dying. It would also bring 5 free only aquatic animals:

Channel Catfish. As size baries, it would usually be 60 centimeters (or 2 feet) long.

Red Bellied Piranha. As size baries, it would usually be about 30 centimeters (or a foot) long.

Green Moray.

Common Bottlenose Dolphin.

The aquatic animals will try their best to never get out of the water under any circumstances, and the Gharial can't get to far away from water anymore, though non-fish aquatic animals will come out partially to breathe. Would add deep diving predation.
Water Changes: Water can now be toggled from freshwater to saltwater, which will affect some animal's health and enrichment. You can now make waves in the water, it requires 2 in game dollars.
Other Additions: When you make a path that leads to water, it now works and an automatic glass tunnel forms. Added free brain coral and tube sponge. Divided aquatic into Freshwater and Marine, with marine using the old logo. If atleast 2 aquatic/semiaquatic animals are found in an habitat with water, the water will include ambient fish, depending on the animal to mach its habitat.


Now, to the actual pack, which would cost 25 dollars since it would be larger than the rest, it would have 32 animals, 25 aquatic, and 8 semiaquatic (none of them are exhibit since you want more accesibility, right?:

Sorry for adding way to much turtles, they are just the best example of semi aquatic animals.

This is probably a hot take, but if we get a marine or fully aquatic animal pack, there's almost no chance they're not going to include the Great White Shark. Even though it's had an overwhelming poor history of trying to be kept in captivity, it is one of the most well known fish in the world. If you took out standard-market/consumption fish (tuna, salmon, and the like), it may be the most well known fish there is. Realistic to include it no, but I think this is a case of "notoriety outweighing realism".

I like many of your ideas though, but that's one I'd have to think would be included that's not on your list.

In actuality for my own list though, I've thought up a marine pack and it would be 20 animals.

Great White Shark
Orca
Bottlenosed Dolphin
Whale Shark
Hammerhead Shark
Beluga Whale
Narwhal
Giant Oceanic Sunfish
Bluefish Tuna
Manta Ray
Electric Eel
Loggerback Sea Turtle
Southern Stingray
Swordfish
West Indian Manatee
Catfish (any species)
Moray eel
Giant Sawfish
Giant Pacific Octopus
Giant Squid

Later there would be another animal pack dedicated as a Marine support pack:

Barracuda
Tiger Shark
Sturgeon (any of the larger species)
Grouper (any species)
Bass (any species)
Northern Pike
Spotted Eagle Ray
Grey Whale

One thing I've noticed with a lot of zoo or aquarium games, aside from the Manta Ray, the rays usually get ignored. As they're a favorite of mine, I wanted to add in two in addition to the Manta Ray.
 
I love this! I know many people love to be Debbie downers and say an Expansion like this is not realistic but God I can dream right? If Frontier ever did this I would literally owe them my life. It is my dream to see fully aquatics and cetaceans in PZ! Marine Mania expansions were my favorite in the OG Zoo Tycoons. I really have faith we'll get fully aquatics someday in this game. It's more wanted for me personally than an aviary pack (that's second though)

Great list, seems you missed some important animals, but it is litteraly impossible to fit all of them in one pack, so good list.

As we have 2 more dlcs that we know of, i hope we could get it (but smaller since this post has very high expectations).
 
Also, other animals i could put:
Electric Eel
Pacific White Sided Dolphin
Common Cuttlefish
Bluefin Tuna
Largemouth Bass
Australian Sea Lion
Sea Otter
Rainbow Parrotfish
Pacific Walrus
Piracuru
