If 3.0 is release, many people wish Freshwater Aquarium Alpha will begin test.
Marine Aquarium 3 will be getting:
- Animated Clams
- Redesigned Fish
- New Fish Behavior
- More Lighting Controls
I believe all of that has to happen before the Freshwater will come close to Beta. The artwork for Freshwater is basically done from what I saw, it just needs the MA3 engine with shaders, etc.
