No,only an amoeba is a single cell organism
Edit:
No. The fish is a multi-cellular organism. Compare a typical fish to yourself. Both have eyes, a heart, internal organs for digestion, and body structures such as arms and fins to help us relatively move. Do you think ONE cell could represent all of these features? And even if there was more than one cell, also think: If all the cells of these features were the same, do you think they could all function differently? No, the differentiation of cells and variety of each kind determine the individual and unique functions. Just like humans, fish are also multi-cellular organisms.
It is worth noting, however, that we all start as a single-celled organism. Upon fertilization, the egg and sperm combine to form the zygote that is one cell. Almost instantly though, the fertilized egg cell divides and differentiation begins.
