There are 20 amino acids used to make proteins. 21 if you count selenocysteine. They are the same for all organisms with a few very rare exceptions. Most living things can manufacture the majority themselves without any need to take them in. Many organisms (including us) cannot manufacture a few of the amino acids on the list and must consume them with our food. Those are called essential amino acids, and the list is different for different animals based on the foods they're evolved to eat.
So it is the same amino acids, but a formulation for fish and a formulation for corals may be different.
