Lava Lizard

Well, hello there.

I play Subnautica on Xbox One X (NOT Series one!) on version from July 2021. I have fun but also I have one problem.

My fish are dying!

And no, not herbivores, the fish that are dying are FRICKING CARNIVORES! Here is the list of fish that I have:

Bone Shark

Cuddle Fish

Gasopod

Jelly Ray

Lava Lizard

Mesmer

Rabbit Ray

Reefback

Sand Shark

And these fish are dying:

Bone Shark

Lava Lizard

Sand Shark

I have a concept to eject Jelly Ray (it isn't very beautiful for me) from the Containment, but I need your help too.

Sorry for bad english, I'm from Poland.

See you.

I played the game in all three survival modes. Now I had a look at the wiki to find out if I missed something. And I read about a creature called Lava Lizard. I immediately checked all my PDAs for entries about this creature. I did not find one. I went to the Lava Zone again. But still, no success.

So what is it? Where can I find it? And is it dangerous?

Edit1: Okay, I found out that it is aggressive.
