To start editing Aquaria (on mac) you'll need to click and select Show Package Contents. Then go to Contents→Resources→Data→Ingredients. This is where you edit what foods do what. Once the file is open, you should see a long string of words like this:

CrabMeat crab-meat Meat
FishMeat fish-meat Meat
FishOil fish-oil Oil
JellyOil jelly-oil Oil
RubberyMeat rubbery-meat Meat
SmallBone small-bone Bone
SmallEgg small-egg Egg

SeaCake sea-cake Cake (+hp)
PlantLeaf plant-leaf Leaf
ButterySeaLoaf buttery-sealoaf Loaf (+hp)
HealingPoultice healing-poultice Poultice (++hp)
MagicSoup magic-soup Soup (+speed ++hp)
etc.

The he more + signs, the more effective it is.

As an example, if you wanted to mod Sea Loaf, it would look like this: SeaLoaf sealoaf Loaf (~hp). The ~hp means it heals you, but only a little. If you want to make it heal more, take the ~ out and add +s. The more +s you add, the more health you will receive.

• +speed is adding speed for 45 seconds.
• +energy is +# to energy shot for 45 seconds.
• +trip is tripping out.
  • The more + signs, the more time. "++" is around 30 seconds, and "~" is one second.
• +regen is regeneration.
• +defense is defense.
• +web is web ability.
• maxhp is maximum health, no + signs needed.
• -blind makes you see better.
• +invincible is self explanatory.
