fish vs fishes
“Fish” and “fishes” are both correct, but they are used in different contexts.
“Fish” is a singular noun that refers to a single type of aquatic animal. For example, you could say “I caught a fish” or “I saw a fish swimming in the pond.”
“Fishes” is the plural form of “fish,” and it refers to more than one type of aquatic animal. For example, you could say “I caught several different fishes” or “There are many different species of fishes in the ocean.”
It’s important to note that the word “fish” can also be used as a verb, as in “I am going to fish for salmon.” In this case, it refers to the act of catching fish, rather than the animals themselves.
