First, we’ll discuss some of the common and popular fish species with the letter U at the beginning from freshwater and saltwater. And later, we’ll mention all the remaining fishes with similar trait. So, let’s get into the main dish.

Most Common and Popular Fishes Starting with U:
1. Uaru Cichlid:
The Uaru, also known as the brainy cichlid, is an uncommon South American fish with a distinctive triangle-shaped body found in sandy rivers. They are not as brightly colored or marked up as other similar types of freshwater aquarium pets.
However, they make up for it by being intelligent and having character traits that set them apart from others.
The Uaru is a fish that thrives in both warm water and clear flowing rivers. They are omnivores, feeding on crustaceans as well as worms or insects depending on what is available. Some people refer to them as chocolate cichlid and Waroo too.
The Uaru is a fish with the classic cichlid’s shape. It has spines embedded in its dorsal fin and, when extended, gives it a triangular profile. The anal fin also extends nearly to the length of the body, making this animal a powerful swimmer!
2. Upside-down Catfish:
The Upside-down Catfish is a popular species that have been admired for countless centuries. It’s named so because its swimming posture makes it easier to feed on top of the water. Also, the blotchy appearance makes it easier to identify.
The upside-down catfish is a freshwater riverine species that can be found in Central Africa. It inhabits the thickly vegetated areas around rivers, and it swims faster when swimming right-side-up.
However, it may shortly switch to an invertebrate mode for short periods while pursuing prey or avoiding predators who are more accustomed to seeing them this way!
The upside-down catfish have large eyes, a forked tail, and three pairs of barbels. Their light brown-colored body is covered with dark blotches that vary in size from small to large.
These fish are colorblind – it takes more than just being able to see well enough not to be dazzled by sunlight! Like other types of “catfishes,” these Catfish also possess sharp fin spines on their undersides which can cause injuries if they’re handled improperly.
3. Unicornfish:
The Unicornfish is a colorful, peaceful species that live in schools. They feed on algae and are closely related to tangs (and surgeonfish). Their horn-like appendage can be upsized when Unicorn fish grow an inch or more long!
The males tend to be larger than females with longer horns; this makes them perfect for fighting over territory. Their skin isn’t as susceptible to bacteria attacks because of its skin smoothness.
Unicornfish are colorful herbivores that live in warm waters around coral reefs. They can be found anywhere from the Indian Ocean to Pacific Oceans. Two species dominate Hawaii: a light blue or green color called “Kala” (Naso unicornis) and the Sleek Unicorn with a silver-colored body.
4. Ulrey Tetra:
The Ulrey Tetra or Broken-Line Tetra is a peaceful, schooling species found only in Rio Paraguay. This shoaling fish makes for an excellent addition to any South American community tank with plenty of shady areas.
The males are known as “tetras” because they have four pairs of barbels that slither around when threatened; females have none! They’re also shy but active learners.
The Hemigrammus ulreyi have a silvery, semi-transparent body with bold black and yellow bands running along their flanks from the eye to the base of the caudal fin. There is also an interruption in these color patterns at about pelvic fins but isn’t completely missing.
The Ulrey Tetra has been named after Dr. Albert B Ulreay, the discoverer of this interesting fish species.
5. Utah Sucker:
The Utah sucker is a piscine freshwater fish found in the upper Snake River and Lake Bonneville areas of western North America. Its size varies from 15 to 25 inches long, though they typically grow no more than 16 inches.
The coloration pattern for this species consists primarily of dark shades with hints of white dots. Those colors may become more vibrant depending upon where it lives along its natural habitat corridor.
