How Saltwater Fish Are

If you’re looking for information on saltwater fish, then you’ve come to the right place. At YourCatCareguide we offer you content for beginners in the fish world so that you can also enjoy a great aquarium, in this case, saltwater fish.

You should know that there are different species of saltwater fish and each species has specific characteristics , whether temperature or ambient. Before buying any fish, you should consult the specific needs of this fish.

Saltwater Fish Needs

Saltwater fish effectively need salt water , which can be achieved by mixing 34 grams of salt per liter of water. These are special packs that you will find in specialized stores. Salt levels should be measured regularly with a hygrometer and should be between 1.020 and 1.023.

The temperature is a very important factor for most saltwater fish. We could place it between 26ºC in a generic way, although as we mentioned there are specimens with different needs.

You should add elements, gravel and vegetation as you would in any other aquarium. The aquarium should be great to welcome all members without bothering each other.

In addition, you should inform yourself and put in your new aquarium a filter for fish hygiene. Thanks to the filter you will not need to change all the water in your new aquarium in a row and it will improve the quality of the environment of your saltwater fish.

Finally, you should place the saltwater aquarium in a place where it receives direct sunlight.

You should also monitor pH levels to be 8.2, nitrate levels at 5 ppm and alkalinity between 2.5 and 3.5 meg / l. Do not worry if you have not memorized all this information, as in the pet stores will advise you properly how to control all these variables properly.


The maids are a perfect option for those who are new to saltwater aquariums. They are solitary fish that measure about 7 centimeters and that resist certain changes in the environment.

But it is important to mention that the maidens are a little aggressive among them and especially with timid fish, for this reason it is imperative to use a large aquarium.


Like the maidens, the famous clownfish is quite resistant to some changes in the environment, although setting them up is a more delicate task.

This deep-sea saltwater fish lives on the coral reefs protected by anemones, which provides them with a cleaning service as it eliminates bacteria from their mouths on a regular basis. This strange friendship highlights the tranquility of the clown fish, except with other clown fish, with which it can become aggressive.


There are over 2,000 species of gobies and are ideal for beginners as they are small, measuring about 10cm and we can find them in different shapes and colors. They live in small communities.

In some cases we find cleaning gobies, which feed on the parasites of other fish. In other cases we can speak of symbiotic fish that act defending crustaceans that provide shelter and food.

Gobies are quite adaptable to slight changes in temperature and / or environment. You should know what is the best type for you.

Pseudochromis magenta

The Pseudochromis magenta is a saltwater fish that do not need a very large aquarium, is a little territorial with other small sized fish and need a habitat with shelters where they can hide.

They are hermaphrodite fish and very bright colors that can marvel and offer a unique aquarium. But remember, you should inform yourself well before you decide to adopt one.

Fish Emperor Angel

The angel fish emperor needs an owner with experience in saltwater aquariums, although it is undoubtedly one of the most beautiful and requested specimens. They do not usually reach 30 centimeters.

It is a solitary fish that adapts to life in captivity and that well-taken care of can reach the 10 years of life. Need a medium to large aquarium and need decoration and rocks to move freely.

Blue surgeon fish

The blue surgeon fish is another example that fish lovers admire for their particular colors. They are large in size, usually measure about 40 centimeters, so they need a large aquarium.

Like angel fish, the fish is solitary and lives on reefs. Its maintenance is demanding since it needs a stable medium and intense lighting, so you will need an experienced owner to survive.
