Fish Police is a police officer.
When everyone noticed that all the glass in the tanks have been smashed, the Fish Police officer, humorously, yelled "Somebody call the police." Later when they found Milo, who was responsible for the damage of the tanks, the Fish Police was about to arrest him. Milo ended up not going to jail after he told Pamela that he is actually a fish, and Pamela told him that she's a gerbil ("Pamela Hamster Returns").
