I know fish and fishes are both correct depending on the situation. But, what would you say in the following situation?
How many fish/fishes can you see in the lake? -> 5 fish/fishes

Both are correct, there is variation in use.
Saying "fish" sounds rather more formal, and so would be the standard use, but a question like this would often be asked to a child or in an informal context, so "fishes" is equally correct.
