Wild Pacus are straving [not a bug]

Hello,

Wild Pacus are starving and dying : they can't feed themselves dispite being next to alguae tile.

Number of Pacus seems to stay the same as they ususally have time to lay an egg.

Bug : it's really depressing to see them deseperatly having kids just to perpertuate their kind, even if they know their kid's fate.

edit : Seems to be a feature, still not kind for wild animals.
