Topminnow

Topminnow refers to a group of small, freshwater fish belonging to the family Fundulidae. They are typically found in shallow, slow-moving waters such as streams, ponds, and marshes, primarily in North America. Characterized by their small size, elongated body, and the dorsal fin positioned towards the posterior, they are often surface feeders, hence the name. Topminnows play a vital role in aquatic ecosystems, serving as a food source for larger predators and contributing to the control of insect populations. Their diet consists of insects, crustaceans, and algae.
