Looks good =)
With Fulgora extended mod (https://mods.factorio.com/mod/fulgora-extended) heavy oil ocean can be replaced with chemical muck.
Can you make compatibility and replace heavy oil with chemical muck in stone bacteria filtration recipe?
This way they will become native to fulgora only and this will bring an extra challenge to bring them to nauvis and keep them alive there.
Looks like bacteria filtration recipe is Fulgora only. Anyway, can you consider to make using chemickal muck insted of heavy oil for stone bacteria recipes on Fulgora?
