</>What does Fish Behavior do?
Fish Behavior lets you reshape how the ocean plays out around you. Swallow Anything removes size limits on whole-swallow bites for your current fish, so even huge bosses can go down in one gulp when the option is enabled. Turn on Super Aggressive Mode to let fish target prey they would normally ignore because of level or species differences. Same Species Attacks adds cannibalistic fights on top of that mode, while Fearless Fish and Stop Fleeing keep the water from turning into a constant panic sprint. Guaranteed Mating makes courtship attempts succeed every time, and Instant Egg Hatching pushes nearby eggs through the hatch cycle immediately. Mix and match the toggles to build calm ponds, chaotic feeding frenzies, or strange breeding experiments.
</>What is Fish Behavior?
Fish Behavior is a Feed and Grow Fish gameplay mod for players who want direct control over feeding, breeding, and AI aggression. It adds separate toggles for whole-swallow bites, guaranteed mating, instant egg hatching, super aggressive hunting, same-species attacks, fearless fish, and stopping flee behavior so you can shape the ecosystem around your current run.
</>Common questions about Fish Behavior
Does Swallow Anything affect every fish?
It applies to your current player fish, letting you swallow targets that would normally be too large.
Does Same Species Attacks work by itself?
No. Turn on Super Aggressive Mode first, then enable Same Species Attacks for cannibalistic fights.
What does Instant Egg Hatching do?
It pushes nearby eggs through the hatch cycle immediately instead of waiting for the normal timer.
Will fearless fish still attack me?
Fearless Fish only removes scared flee reactions. Aggressive fish can still hunt and bite normally.
