Brackish Fish for Home Aquariums: What They Are and How They Live

Beyond the saltwater fish and freshwater fish lie species of fish that many aquarium owners might not talk about quite as often: brackish fish. Brackish fish allow for an amazing combination of the best of both worlds, and they open up possibilities for intriguing aquarium designs.

What Brackish Fish Are

Brackish fish live where freshwater meets saltwater, where rivers flow into seas or oceans. Brackish water has more salt than freshwater, but not quite as much as oceans. Certain freshwater fish can adapt to a brackish environment, but some species of fish only live in brackish waters.

Brackish aquariums are a combination of freshwater and saltwater tanks. They’re not extremely common in the aquarium hobby, although some people do enjoy keeping brackish tanks and the hobby is becoming increasing popular.

These tanks also provide the best of both worlds in terms of cost and beauty. They tend to be less expensive to maintain than saltwater aquariums, but hobbyists have options for beautiful and unique fish like they would in a saltwater tank.

Because of their natural habitat, they can tolerate a wide range of salinities. Ideally, the water would have a salinity of 1.005 and 1.012 and a pH of 7.5 to 8.4 with alkalinity between 180 ppm and 360 ppm.

There’s one important aspect to note. Because the salinity of brackish water changes with the flow of the water, fish in the wild learn to adapt by moving to more ideal habitats. Because fish can’t relocate in a tank, the challenge of owning a brackish tank is in maintaining an appropriate salinity. In other words, the fish can’t move to where they’re more comfortable like they would in nature, so you have to provide them with a level of comfort that’s acceptable at all times.

Popular Brackish Fish Breeds for Aquariums

Certain types of mollies are brackish fish.

Certain types of mollies are brackish fish.

Following are a handful of waters that are considered brackish:

  • Baltic Sea, located between Sweden, Finland, and Poland
  • Black Sea, located between Romania, Turkey, and Georgia
  • Hudson Bay, located in central Canada between Nunavut, Manitoba, and Ontario
  • Caspian Sea, located between Europe and Asia
  • Lake Charles in Lake Charles, Louisiana

There are some “true” brackish fish, and some freshwater fish that can adapt to the environment.

Two of the most popular brackish fish for home aquariums include Mono Sebae and Mono Argentus. These amazing fish do well in regular saltwater tanks as adults, but they can live in freshwater as juveniles.

Other popular brackish fish include:

  • Figure 8 Puffer/Pufferfish
  • Green Scat
  • Archer Fish
  • Various species of goby, including Bumblebee Goby and Violet Goby
  • Various species of mollies, such as Black Sailfin Mollies and Balloon Mollies
  • Four-Eyed Fish (Anableps)
  • Drum Fish
  • Tigerfish
  • Asian Cichlids

Aquarium Installation: Basic Components of a Reef Tank

We love saltwater reef tanks for many reasons. If you’re planning to have a saltwater aquarium installed in your home soon, we have no doubt that you will be just as entranced as we are. Whether you’re working with Seatech Aquariums or installing the fish tank on your own, it’s important to understand the basic components of a reef tank.

A reef tank is gorgeous, but you need several basic elements to ensure it stays as beautiful as it was on Day One.

Components of a Reef Tank

1. The Tank

It’s important to choose a properly sized tank for the quantity and breeds of fish you will have in your aquarium. You will also have to decide whether you want an acrylic tank or a glass tank.


2. The Plants

You can use either artificial plants or live plants in your reef tank. There are numerous differences, but here’s the long and short of it. Artificial plants may be easier to maintain, but live plants are prettier, more natural, and possibly offer more health benefits to the ecosystem with the proper maintenance.


Whatever you do, including plants in your reef tank is a must for several reasons:

  • Improved health of the fish
  • More enjoyment for the fish
  • Increased security for the fish
  • More oxygenation within the aquarium
  • Natural filtration of the water
Components of a reef tank should include plants and coral.

3. Gravel

Gravel serves as natural filtration for an aquarium. It also traps some of the matter to keep it out of the water. Additionally, some animals like to burrow into it for safety and play.

Remember to include gravel and bottom feeders, such as this Cory Catfish, in your saltwater reef fish tank.

4. Filters

Having a filtration system in the tank is a must. The types of filters you should use depends on the size of your tank, as well as the species and quantity of livestock. There are a wide range of styles and brands, so if you’re not sure which type of filter is best, contact us for guidance.

5. Lights/Heaters

Some saltwater fish prefer cooler water, but others do need warmth. You will also need lighting to beautify the tank and to allow you to see inside. You can buy them separately or purchase one device that provides both heat and light.

6. Coral

The highlight of choosing a reef tank is to be able to add the beautiful coral. Coral aids in the development of a natural environment for fish, and it beautifies the tank like nothing else can. The appearance, quality, and size of coral is as varied as the fish in your tank, but some hobbyists prefer certain types of coral over others.

Much of the beauty of a reef tank is in the coral. Coral such as this Euphyllia Hammer Coral add color and excitement to your saltwater fish tank.

7. RODI Salwater

It’s clear that you need filtered water for the tank. Never, ever use tap water, as the chemicals in tap water can irritate the skin and eyes of your fish. Specifically, we prefer reverse osmosis deionized water for fish tanks, and it’s all we use to fill tanks and clean the tank and decor.


8. Bottom Feeder

Bottom feeders such as catfish and shrimp can be an intriguing addition to your reef tank.


Many bottom feeders have unique characteristics and appearances, further enhancing the beauty of your tank. Most importantly, they can help keep the aquarium healthier by eating the algae, leftover food, decaying plants, and natural debris that may be at the bottom of the tank.

Ghost shrimp are among the most popular bottom dwellers and least expensive shrimp for a fish tank.

9. Rock

Whether you choose live rock or dry rock, be sure to include at least one in your tank. Similar to the gravel, plants, and bottom feeders, they serve as natural filters. Additionally, they can provide a place for shy animals to hide and playful animals to play.

Components of a reef tank include rock and other decor.

Adding live rock, artificial rock, and decor into your reef tank serves several purposes, including beautifying the tank, filtering the tank, and giving the fish a place to play.
