I noticed my fishes exhibiting some strange behavior a few days ago.
Usually they don't touch or move stones, but I can see a big stone pyramid .
For what?
I don't know.
It looks like they tried to clear a big space, a space without any stones.
I recorded a short video how they move stones:
The most surprising fact is that after they cleared the space and constructed the pyramid, they spawned in a totally different place!
So, it's looks like they just try to make good view.
