If there are windows on your base, I think the fauna should show more interest in us humans.
For example:
Marrowbreach should occasionally do slow drive-bys like a shark eyeing its prey.
A group of Nibblers should occasionally gather outside and watch us like a monkey in a cage.
Maybe clown crabs can continuously jump up and down to reach the windows to watch us, like a kid trying to look over a fence.
There are infinite possibilities for this.

This sounds fun. Especially setting up in deeper areas when the creatures get more and more deep sea freaky, having them come peek in the windows would be awesome
