Wild Pacu farm

[Sevio]

So I'm at a point in my playthrough where I've discovered a whole bunch of ponds with Pacu in it, I want to empty them out to clean the polluted water in my water sieve, I also want to keep the wild Pacu alive and get some free egg shells whenever a new one hatches. Each one needs 8 water tiles to be happy and that is a lot of water to commit for collecting all the wild Pacu.

So I did some testing and figured out how to build the smallest room that can keep a wild pacu happy with a minimum of water. From my testing, it turns out that pacus tend to "look" for water to be happy in a strange way, it seems they only look to their right, up and down but not to the left. They also need to be in a tile at least 350 kg of water to not flop about, but other tiles of water don't need to be that much to count towards being happy.

So with that in mind, this seems to be the smallest amount of water that a Pacu will be happy with:

Pacu seem to lay their eggs around age 15 and the egg takes 5 cycles to hatch, so even though the old Pacu will be glum once the egg hatches, the fry shouldn't be glum for more than 5 cycles. Any further Pacu should lay their egg at age 20 and die right when the next egg hatches.

It's a great shame that there isn't a system to untame a creature. I feel like I'm running a zoo, not a ranch these days.

I want to to de same with my current base, but in a vertical way. Water pressure isn't a problem with glass?

So I realized there is a flaw with the mini pacu room design: because the fry will be glum for 5 cycles, it ends up slowing down how fast you get the next egg, so I figure it's better to max that by providing each pacu a pool big enough for two. And in the interest of stacking, I think this layout might be the best balance between low water requirement and space efficiency.

The water pools are at 400 kg per tile, which is a lot more than the mini pacu room earlier. If you really want to minimize the water content of each pacu room, you could do it like this but it wouldn't stack as nice.

You can do this but you will be unable to sweep the shells from the new and the meat left by the dying paku. And yes the glass can support the water.

actually since you don't need dupe access to the 1 tile water on the right, you can make their roofs 1 tile shorter and it will make another room that mirrores horizontally to stack up nicely on top of it.

Unfortunately that doesn't work. You cannot mirror this room because the pacu will be unhappy if he's stuck on the right side of the room. They only "look" to the right but not to the left when deciding how happy they are.

that sounds buggy thanks
