[No spoilers] if I release my beloved at 160m will they die?

No spoilers please, I just unlocked alien containment and am in over my head lol

I hatched my first eggs (lava lizards) and I adore them- I love how the eggs bounce and pulse, I love that they're like lizard dolphins, they're so cute 10/10.

They are my best friends, but they have started reproducing and I need to let some go bc there's so many in the tank. My base is at 160m depth but I got the eggs from much deeper- if I let them go outside my base will the pressure difference kill them?

Also do I have to stock the alien containment tank with feeder fish to keep them alive?
