Aquarium

Hello! I’d really love to see aquariums and creature eggs return in Subnautica 2. The Alien Containment system from the first game was one of the most memorable and fun mechanics. Being able to hatch eggs, raise sea creatures, and create your own living ecosystem inside your base made the world feel much more alive.

I’d especially love to see:

large Alien Containment-style aquariums,
more rare and unique eggs,
improved hatching animations,
new creatures that can be raised,
deeper interactions between creatures.

This feature was a big part of what made the original Subnautica so special, and it would add a lot of creativity, immersion, and replay value to Subnautica 2 as well

i think this is one of the thing thatll come regardless since its just ea eight now but yeah i fw the improved aquarium/creature system

by the gods yes

Please yes! Making aquariums for fish and creatures was always so cool in the past games!
Especially when the creatures repopulate in an aquarium so you always have food or water.

Oh please yesss!!!

Tied in with this, I would really love an expanded experience that makes me feel like a marine biologist(xenobiologist?) maybe a lab room type, collecting samples and using them for upgrades, maybe breeding different variants of fish even? I know it’s not the main focus of the game but I personally loved to play the first subnautica in this sort of way. Even tying certain research tasks to story progression might make the bases even more integrated with the gameplay loop, and it’d just be cool

You could really expand on this with the new base building. Imagine having water tubes connecting aquariums with fish swimming between them. That could also be useful as a quick way to navigate larger bases with the Seaglide glove things!

Fish pens would be great. Like a moonpool but with different biomes for different fish

~The aquariums were one of the best ideas in the first two games!
Plus, they made the bases homey with the ability to fill them with colorful plants and creatures!

I would love to see them added to this game as well!! 💙💚🌊

Example of things that could be put in them
Periscope Clowncrab - Catchable
Jetocaris - Catchable: The young only, the old could protect them when taken
Coral Crab - Young could be found and tamed
Foureye - Tamable

Edit: I did not realise i already put this

Defitivamente precisamos da volta do aquário neste jogo para voltar a imersão e também a criação dos peixes.

**it would be cool if the fish started reproducing in the “makeshift aquarium “ that you can currently build

I agree with repopulation, but I think new species of fish would be a lot for the devs, or the randomizer creating the new fish. However, color variations would be really cool. Aquariums are a must, and the devs really should find a way to make it happen.

Crazy to have predatory levitations as decorations in fish tanks from eggs

I’m hoping for a high level of customization for the habitats, like the ground color (pick between different materials like sand/rock) add props (like coral or rock) and change lighting for creating deep water tanks.
