Top 9 Surprising Facts About Your New Saltwater Fish


Everyone is enamored with the vibrant hues of saltwater fish, and it goes without saying that having these beautiful creatures in one’s home provides a colorful boost. However, there are several facts regarding saltwater aquarium fish that you likely did not know.

The vast majority of people have relatively limited fish-related knowledge. We’re probably all cognizant of the fact that they can range from small to large and that they can be any number of colors and shapes. 

However, each category appears to have its own distinct character, which gets people thinking. After reading this article, you will be up to date on the most prevalent information regarding the amazing facts of saltwater aquarium fish.

So, shall we?

Ocellaris Clownfish – Most Commonly Kept Saltwater Fish In Aquariums

The Ocellaris, or “common” clownfish, is often considered to be the most popular species of saltwater fish in the entire globe. This fish is a perennial favorite because of its stunningly bright orange coloring, white stripes, and endearing waddling action when swimming.

Saltwater Fish Drink Water

When thirsty, saltwater fish sip water just like their freshwater counterparts. Because of osmosis, they need to replenish the water that is being lost from their bodies through perspiration. 

Fish living in freshwater don’t need to drink since their bodies absorb the water around them.

Goby, Or Yellow Watchman

Shrimp and fish are great starter species for saltwater aquariums. The yellow watchman goby is a great choice if you’re just starting with saltwater fish. 

They are vibrant, hardy, low-cost, and have the incredible bonus of a fascinating behavior to observe. A well-known fact about this fish is the shrimp species with which it lives in mutualistic harmony.

Although it is not recommended that a beginner try to pair a goby with a bonded shrimp, both the goby and the bonded shrimp are wonderful saltwater fish for beginners to get.

All Of Their Senses Are Put To Use

Fish utilize all five senses to find food, avoid danger, and communicate with one another, albeit they may not function quite like ours.

Just like you make sure your home is secured with the best and smart locking mechanism by an expert fingerprint door lock supplier, fishes also build their secure homes in coral reefs and make sure they have a good security system using pebbles and other sea elements. They sense everything around. 

Make sure you provide the tank according to your fish requirements for them to survive better. 

A Fish’s Brain Is A Complex One

The intelligence of saltwater fish is often overlooked. It’s important to keep a close eye on your fish if you want to decipher the signals and behaviors they use to communicate with one another (and with you).

The Ability To Feel Pain And Experience Suffering Are Not Unique To Humans

While we may not be able to tell if a fish is scared, happy, relaxed, or playful just by looking at its face, there is growing evidence that fish feel a wide spectrum of emotions. 

Similar to humans, fish have pain receptors, become stressed when confined, and tend to avoid potentially dangerous situations. A fish’s agony and stress levels skyrocket when she is yanked out of the water by a hook driven into his mouth. So avoid playing such games with your dishes. 

Also, when you plan to clean the tank or introduce new ceramic filter media to the aquarium, always make sure the fishes are in the safe zone or transported safely. Working while they are still in the tank might trigger their stress levels. 

Not Every Fish In The Sea Is Your Friend

Many fish are classified as “community,” “semi-aggressive,” or “aggressive” based on their behavior; however, not all members of a given group will get along. It’s possible that some fish species get along with others but are exclusively friendly within their own species to mated pairs. 

Some male fish are quite territorial and will fight if you introduce any new males to their harem. Before adding a new species to your aquarium, you should study its habits and personality traits to ensure it will get along with the current inhabitants.

Every Single Fish Has Its Own Distinct Character

Most of the time when we think about fish, we picture a homogenous group. New evidence suggests, however, that fish have distinct personalities, with some being more outgoing and exploratory than others. 

Like humans, fish have different personalities based on their genetic makeup and their upbringing. For example, some fishes might keep on jumping out of the tank while others swim peacefully. 

Or you might find some fishes being friendly when you introduce your hand with gloves on, while others may get scared to death. Meanwhile, choose among nitrile vs vinyl gloves for tank cleaning purposes. Any of these two materials are the best for water related tasks. 

Salmons Are Familiar With Their Birthplace 

It took a while, but we now know that goldfish have a long-term memory that can persist for months at a minimum: a trait previously thought impossible. 

The ability of a salmon to return to her spawning grounds by following her nose after several years is perhaps the best evidence of fish memory ever discovered. She remarkably recalls the aroma of the brook where she was born. 

On their arduous trek upstream, salmon often face powerful currents, predators, and even waterfall leaps.


An excellent first fish should be calm, hardy, low-maintenance, and cheap. We hope the information above has piqued your interest in setting up a saltwater aquarium in your house, whether you’re just getting started or are looking to add a new, beautiful resident to an existing reef setup.

Have fun caring for marine fish!
