Best Names of Fish That Start With S

Here is an interesting list of 300+ names of fish that start with S. The most common fish names by far start with the English letter S.

This list is for both saltwater and freshwater fish species.

We’ve got speckled, spotted, striped fishes and a few shiny silver ones on this list. I hope you’re going to enjoy this long list of fish.

We have included Scientific names to provide you with even more in-depth information about each of the fish that are included in the list.

To identify various fish breeds Latin names are used and categorize the breeds.

In the scientific nomenclature, organisms, plants, fish, and animals are given many categories and classifications so that they can be properly identified by researchers and scientists studying these living things.

The following headings (from highest to lowest) are included in the classifications:

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

All the animals or creatures that have been identified get arranged into these classifications.

Below is an example that has been set up for one of our preferred aquarium fish – Betta and Siamese Fighting Fish. They are classified in the following manner:

  • Kingdom: Animalia
  • Phylum: Chordata
  • Class: Actinopterygii
  • Order: Anabantiformes
  • Suborder: Anabantoidei
  • Family: Osphronemidae
  • Genus: Betta
  • Species: splendens

These classifications will be generated for each new type of fish and all the fish are categorized in this way that gets discovered in the future.

Our Top 5 Fish Names Beginning With Letter S

For our top ‘S’ fish list we struggled a little bit with our choices as there were a lot to choose from. However, we’re very happy to say that we have chosen our ultimate five and hope you’re going to appreciate them too.

Here we’ve selected a few very pretty fish and one not-so-pretty fish. But they’re all worth a special mention and super interesting.

Sailfin Molly (Poecilia Velifera)

The extra-large fin on the back of Molly fish is what provides them the name Sailfin Molly, as it really seems like a boat sail.

You will find these fish in the wild environment in Israel, Colombia, Mexico, Singapore, and Taiwan, where they survive in brackish waters.

You have to ensure that the hardness of water is correct while setting up an aquarium for a Sailfin Molly as they tend to become weak in soft water.

These fish don’t mind a little direct sunlight. Again, they can also withstand higher temperatures as compared to so many other fish.

Keep your sailfin molly in highly planted aquariums, perhaps with floating cover, however, to have a swim, leave some open rooms for these fish.

Feed them with a mix of dried, frozen, and living foods. My suggestion is to include some greens to keep and maintain these omnivores as balanced as possible – blanched spinach or cucumber is ideal for them.

Since Sailfins are friendly-natured, they can live with other fish in an aquarium, the only thing you have to avoid is teaming with any fin-nippers.

Salvini Cichlid (Cichlasoma Salvini)

Like many other cichlids, Salvini Cichlids are highly aggressive creatures. So if you want to keep multiples of Salvini Cichlid, it is necessary to give sufficient hiding spaces for them, and in this way, their territorial angst can be reduced as much as possible.

They are predominantly carnivorous species, therefore they will enjoy frozen and live foods as well as pellets – for added nutrients some spirulina flakes might also be added to the mix.

Salvini prefers a huge space for the purpose of swimming. They also like hiding places and a few plants around the aquarium. As we know, this carnivorous fish likes to consume live food, which includes any fish that fits neatly into its mouth, so you should be careful while selecting tank mates for this species.

Seba Mono (Psettus Sebae)

In our top 5 list, we decided to include the Seba Mono fish because we just love and appreciate the shape of this fish species! It doesn’t seem everything is practical for swimming however when it comes to the involvement of food, the Seba Mono fish looks to spring to life in order to nab itself a great juicy live piece of food.

As tank mates, small-sized fish may not be best suited, as the Seba Mono fish can eat everything live that fits in their mouth.

This fish can be kept in a salt (or brackish) environment and also can be kept with any peaceful fish except the odd accidental nomming of aquarium mates.

It is recommended to have Coral sand as a substrate for your Seba and a lot of aquatic plants make this species feel at home.

Siamese Fighting Fish (Betta Splendens)

The Siamese Fighting Fish is one of our all-time favorite fish. They are also known as Betta Fish and Japanese Fighting Fish.

Often, these fish are colored and sometimes patterned very beautifully, with a lot of different fin styles making this fish a pleasure to watch in a tank.

These types of fish are extremely territorial and they should not be kept along with others of their kind.

Tankmates that suit a Siamese Fighting Fish are shrimps, corydoras, and various bottom feeders – but we recommend you avoid colorful fish that your male Betta might see as their competition.

Betta fish will flare when angry – their gills of your betta stick out to the sides and their fins become outstretched. Again, this is how they appear while trying to attract a female Siamese too! If a betta is feeling comfortable and safe it will make a bubble nest.

Snakehead (Channa Argus)

We’re unsure about you, but if we went swimming in a stream or a river and if this fish appears in front of us, we will be quite unsettled.

The Snakehead fish seems quite unfriendly and unusual, don’t you think? These species grow quite big – the biggest catch recorded was caught in 2018 and measured over 35 inches long and weighed 19.9 lbs – so we’d certainly freak out.

Just like a snake, it can wriggle across the land to arrive in other parts of water, living out of water for so many days! Since they are large-sized, this species isn’t a fish that could be kept as a pet and if you notice them in day-to-day life, they will be found on your dinner plate. This freshwater fish is a popular food in Asia. It was introduced in the wild across some regions of the US and Europe.
