Now that Subnautica has officially left Early Access (yay!), I've started playing it again. I've heard rumors about a new creature that is tamable as a pet called the Cuddlefish, but I don't know where to find it. I've searched a few of the nearest biomes (Safe Shallows, Kelp Forest, Grassy Plateaus, and Crags) but I've had no luck so far. I don't want to look it up in the wiki just yet because I'm trying to avoid spoilers. Where can I find it? Do I need anything special to tame it?
So far, I've only seen people find them in the first location above, as seen in this video. After you obtain the egg, place it in an Alien Containment tank and wait for it to hatch (apparently its about 1 to 3 in game days).
