What Are Small Fish Called?
Depending on the species, the small fishes can be called different names. These include the neon tetra, skeleton shrimp, Clown Frogfish, Gurnard, Platys, Harlequin Rasbora, sea trout, and Pollock.
Stout infant fish
Previously known as the good stout fish, the Stout Infantfish is paedomorphic species that retains its infantile characteristics in adulthood. It is a member of the genus Schindleria and is native to the Great Barrier Reef. It is the world’s smallest known vertebrate.
The stout infant fish is also the world’s smallest, measuring less than a pencil’s width. The stout infant fish has a small but complex body structure and a short life span of two months. It feeds on plankton and smaller fish.

Adding some small fish to your aquarium can add color and life without costing too much money. While many small fish are juveniles of other fish, some are plain old minnows. Some even have unusual names.
The smallest fish in the world is the male Photocorynus spiciness. Its name is a bit of a mouthful, but the male is the smallest vertebrate ever to grace the earth. The minor female is approximately 721 percent bigger than the male. These anglerfish are found in tropical and subtropical waters. They are also notable for their bio-luminous bulb that lures prey into their mouths.
Harlequin Rasbora
Originally referred to as Rasbora heteromorpha, the Harlequin rasbora is a species of rasbora that is found in swamp forests. This species has a round body with short fins and an orangish sheen to its coloration.
These shoaling fish eat a wide variety of foods, including insects, worms, meaty foods, and detritus. The male Harlequin rasbora tends to have a brighter appearance than the female. The female also becomes plump and full-sized during the breeding season.
The Harlequin rasbora can survive in various water types, including hard water. It will do best in a long tank with a densely planted habitat.
Neon Tetra
Originally from the Amazon River basin of South America, the neon tetra is one of the most popular aquarium fish. These small fishes are easy to care for and are popular aquarium partners.
Like most fish, neon tetras have specific habitat requirements. They thrive best in slightly acidic water and water with tannins. In addition, neon tetras require particular water conditions for mating.
Neon tetras are very hardy fishes that can live for years. As a general rule, neon tetras should be fed once a day. This can be frozen food or high-quality flake food. Freeze-dried blood worms are a good choice for flake food.
Clown Frogfish
Whether you’re a diver or looking for an incredible new animal to photograph, you may be interested in small fishes called clown frogfish. These ferocious predators are found in the tropical waters of the Indian Ocean, the Eastern Atlantic, the Pacific, and the Red Sea.
Clown- or Warty Frogfish are ferocious predators attacking small fish and shrimp. They are usually found in rocky, rubble, or open sand areas also their dorsal spine to mimic sponges and nudibranchs. They can change their color to blend in with the surroundings.
Platys
Platys are small fishes that are a member of the Poeciliidae family. They are native to Central American waters. And they can live in saltwater but are most often found in freshwater. are known for their prolific breeding habits.
Platys are omnivorous and prefer a variety of foods and do well in community tanks. They do not require a lot of room and can be kept in aquariums from as small as 50 liters. They also do well in tank conditions that mimic their natural habitat.
Skeleton shrimp
Usually, skeleton shrimp are found in marine environments, where they are essential bioindicators of environmental health. They inhabit a variety of organisms, including algae, seagrasses, hydroids, bryozoans, sponges, and even docks.
Skeleton shrimp are marine crustaceans belonging to the order Amphipoda. The order includes nearly 10,000 species, and roughly one-third are freshwater species. Their body segments are uniquely segmented, with a pronounced sexual dimorphism. Some skeleton shrimp species are predators, while others are filter feeders. The term skeleton shrimp originates from the shape of the body.
Brown trout, sea trout, and Pollock
Initially a European species, sea trout have spread worldwide, from the Pacific to the Atlantic. The Atlantic Salmon Trust produces a guide to sea-trout recognition.
Sea trout, also known as anadromous brown trout, is found throughout Europe, the Black Sea, Iceland, and the Arctic Ocean. Their population is under pressure due to habitat destruction and overfishing.
Sea trout are usually found in coastal waters but are also known to live in saltwater. They may have started life in a lake but will eventually migrate back to freshwater to spawn.
