The term 'Tiny Carps' is a reference to the small freshwater fish known as Nits, which have four letters. Nits are a type of minnow that are found in many parts of the world, including Europe, Asia, and North America. They are usually less than two inches in length and can be found in streams, ponds, and lakes. They feed on small insects and other aquatic organisms. Nits are popular among anglers for their small size and abundance.
