The fathead minnow(Pimephales promelas) is a species of temperate freshwater fish belonging to the genus Pimephales of the cyprinid family. The natural geographic range extends throughout much of North America, from central Canada south along the Rockies to Texas, and east to Virginia and the Northeastern United States.... The fathead minnow in its wild form is generally dull olive-grey in appearance, with a dusky stripe extending along the back and side, and a lighter belly. There is a dusky blotch midway on the dorsal fin. Breeding males acquire a large, grey fleshy growth on the nape, as well as approximately 16 white breeding tubercles on the snout.

Pilot fish,(Naucrates ductor), widely distributed marine fish of the family Carangidae(order Perciformes). Members of the species are found in the open sea throughout warm and tropical waters.... The pilot fish is elongated and has a forked tail, a lengthwise keel on each side of the tail base, and a low first dorsal fin. It grows to a length of about 60 cm(2 feet) but is usually about 35 cm long. It is distinctively marked with five to seven vertical, dark bands on a bluish body. The pilot fish is carnivorous and follows sharks and ships apparently to feed on parasites and leftover scraps of food.
