Fish That Start With S [Extensive Freshwater & Saltwater Fish Name List]

While finding names of fish that start with S may not be daunting, getting them all together in a list is definitely a daunting task. The list of fish with names that start with S is almost unending.

S starts the name of so many interesting fish. So there is a need to specifically identify one fish from the other. Scientific nomenclature is the system of identification that makes it possible to tell one living organism from the other and even distinguish between two very identical species.

The living organism is classified from the highest group to the lowest subgroup with the following classification:

  • Kingdom
  • Phylum
  • Class
  • Order
  • Family
  • Genus
  • Species
  • Subspecies

This is the same with fish as it helps identify one specific species from another closely related and very identical species. For example, check how it applies to the Siamese Tiger fish below:

  • Kingdom: Animalia
  • Phylum: Chordata
  • Class: Actinopterygii
  • Order: Perciformes
  • Family: Datnioididae
  • Genus: Datnioides
  • Species: Pulcher

Our Top 6 Fish Names Beginning With Letter S

This list of our top 6 fish names that start with S is a great place to start if you are looking for names of fish that start with S.

Picking these 6 top fish species from the list of fish below was challenging. As many hobbyists would agree, there is hardly any aquarium fish that is not special. From the peaceful fish to the not so pretty fish, hobbyists see them as special. But these 6 are worth the hype.

Seba Mono (Psettus sebae)

African moony in an aquarium

The beautiful, exceptional shape of the Seba mono earned the fish a spot on this list. The Seba mono is usually peaceful and will mind its business.

But it will also spring back to life with energy during feeding time to get its “piece of the pie.”

It prefers brackish water and can cohabit with other peaceful fish. But you don’t want to keep it with smaller fish as the Seba is known to eat smaller fish that can fit into its mouth.

You want to use coral sand as a substrate for the aquarium and provide plenty of aquatic plants to make this fish comfortable.

Salvini Cichlid (Cichlasoma salvini)

The Salvini cichlid, like many other cichlids, is territorial and aggressive. Their anger and territorial nature tend to keep the community tank active. But if you wish to keep more than one in a tank, a large tank with sufficient space for these territorial fish would do a lot to limit the show of aggression.

Although it might eat plant matters sparely, this fish is largely carnivorous. They will also do well with pellets that are specifically designed for carnivores. But they enjoy live and frozen foods.

It is best to keep them in a large planted tank that closely replicates their natural environment to provide them enough room to swim and enough covers to hide.

As with many other carnivores, you want to be very picky when choosing tank mates for the Salvini Cichlid. They will eat tankmates that are small enough to fit into their mouths.

Sailfin Molly (Poecilia velifera)

As the name implies, the Sailfin molly has a huge dorsal fin that looks like the sail of a boat. This unique trait earned the fish its place on this list.

The Sailfin Molly is a hardy fish species that prefer hard water. They live in brackish waters in the wild and have the ability to the ability to adjust themselves to various salt levels in the aquarium.

Although they can cope with a bit of sunlight, they love a heavily planted tank with floating covers. But they also love to have enough room to swim around.

They are omnivores and will do well with a rich and balanced diet. You can feed them live and feed dried foods but always add leafy greens to their diet.

Do not house the Sailfin molly with notorious fin nippers like the betta species, barbs, and tetras. They will ruin the beautiful dorsal fin of your Sailfin molly.

Snakehead (Channa argus)

Channa micropeltes

This fish is called the snakehead because of its ability to survive on land for days as it wriggles its way like a snake on land to another water body for survival!

It is a very interesting freshwater fish, and it grows enormously. Sometimes, a snakehead can grow more than 30 inches long and weigh more than 15 lbs.

The size of the fish makes it a very expensive investment for the hobby. It is not a fish you want to keep as a pet. But the size also makes the fish a prize for Asian fishermen as it is a famous food in Asia.

Siamese Fighting Fish (Betta splendens)

Also known as the Japanese fighting fish, the siamese fighting fish is a very colorful fish with beautiful fins that make them great display fish. They are also called betta fish.

The Siamese fighting fish is very territorial. It would be best to keep only one in a tank except when you temporarily house a male and a female betta fish for breeding purposes.

Avoid choosing colorful tankmates for the Japanese fighting fish. Although small, male bettas will often become aggressive toward other fish with vibrant colors. They may see them as competition. So you want to avoid colorful fish.

Suitable tankmates for the siamese fighting fish are corydoras and other bottom feeders.

Be sure to catch them when they stretch out their fins for a breath-taking sight. They will usually do this to attract a female or when they are angry.

Spotted Bristle-Nosed Pleco (Ancistrus hoplogenys)

Baryancistrus fishes in aquarium

The Spotted Bristle-nosed pleco is a nocturnal and easy-going fish. They usually have extended branched antennae, which is usually noticeable in males when they mature.

The spotted bristle-nose pleco is largely herbivores but will not hesitate to devour bloodworms, insects, and shrimps if fed.

They are native to the tropical northeastern South America and prefer an aquarium environment that replicates their natural habitat. They like a well-filtered tank with lots of plants and hides.

If you do not provide covers for them, do not be surprised to see the males trying to dig up your tank’s substrate to make one for themselves. They need a lot of hides and covers at the bottom of the tank to keep them comfortable.

They love a spacious tank as well. Ensuring that they have enough room to swim, hide and explore is very important if you want them to stay stress-free.

Final Thought

This list of fish with names that start with S is by no means exhaustive. Scientists continue to discover new fish species as they study nature. But the classification system has made it easier to identify them and classify them appropriately.

So any new species in the family of these listed fish or a new order or class will be classified accordingly. But this list of fish is a great starting point.
