Aquarium Brine Shrimp (Artemia salina)

brine shrimp

Brine shrimp, also known as Sea Monkeys, sea dragons, or Artemia, are tiny crustaceans that can live in aquariums with fish. They are bred and sold commercially as food for many types of saltwater fish, including some tropical fish that need brackish water like marine angelfish and butterflyfish. Because they don’t need much room to swim, they’re perfect for larger aquariums and fish ponds too.

They are tiny crustaceans that live in the Great Salt Lake and the oceans of the world. They can be used as feed for most marine animals, including fish and reptiles. They have many nutritional properties that make them useful to humans as well, including high protein content.

If you have your own private source of brine shrimp or buy live one from an aquarium store, then you can use them in a wide variety of ways in your aquarium, from feeding your fish to adding color and nutrients to aquarium water.

They can be found in abundance in lakes, ponds, and even saltwater habitats.

These aquatic creatures have been kept in home aquariums since the early 20th century, and are used in many types of scientific research today because of their short lifespans and ease of breeding.

Their larvae are sometimes called sea monkeys because they vaguely resemble the popular toy-like animals of the same name that were sold during the 1960s and 1970s.

There’s plenty more to know about these fascinating creatures, so take a look at this guide to everything you ever wanted to know about this crustacean!

What are brine shrimp?

brine shrimp

It’s called brine shrimp and is classified as a crustacean – an aquatic animal with numerous legs and a hard exterior shell. They are commonly used as food for tropical fish in aquariums.

All varieties of brine shrimp share a single species, so there isn’t much difference between one type of brine shrimp and the next. They generally possess stalked compound eyes and thin, worm-like bodies consisting of a trunk from which eleven pairs of thin, leaf-like legs sprout.

Origin and description

They are a type of crustacean that live in salt lakes and oceans. Their bodies consist of three segments: head, thorax, and abdomen. They have six pairs of appendages on their heads called antennae; these are sensory organs that help to find food.

They also have two compound eyes and four sets of maxillipeds with mouthparts attached to them. Most of them only live up to eight weeks but some can survive up to six months. Saltwater is what helps the brine shrimp stay alive because it helps regulate osmotic pressure between cells.

Brine shrimp scientific name

Their scientific name is Artemia salina

Brine shrimp habitat

They are crustaceans that can survive in environments with high salt concentrations and low oxygen levels. They are found in the Arctic and Antarctic, as well as in salt lakes and salt mines around the world.

Additionally, they live in evaporation ponds built by humans for obtaining salt from the ocean. The maxillary glands produce concentrated urine, which absorbs and excretes ions as needed according to the salt content in their environment.

There is also a wide range of temperatures in the water throughout the year, ranging from about six to 37 degrees C, and the optimal temperature for reproduction is around 25 degrees C or room temperature.

They are relatively safe from predators because of their salty location, but their diet is limited because of it.

Brine shrimp size

Brine shrimp size is about 0.4 inches (1 cm) in length.

Tank size

Their tank size can range from 5 gallons (18.9 liters) to 10 gallons (37.9 liters). The larger the tank size, the more brine shrimp you can keep alive for a longer period of time.

Tank mates

Brine shrimp are best kept in species-only tanks. This is because they are great food for other fish in your tank, and they will mostly get eaten if kept with other species.

Substrate

You can decorate your brine shrimp tank with rocks and a sand substrate if you keep them as pets.

Are they aggressive or peaceful?

Brine shrimp are peaceful, inoffensive, and will not attack other organisms. The downside to this is that they can get eaten by adult fish if added to a community tank.

Brine shrimp care

Despite being tolerant of crowding, brine shrimp may need additional containers as they grow. Additional water should be premixed and stocked for later use. You should remove any dead brine shrimp from your habitat on a weekly basis. If your tank needs water because it is dehydrated, do not use salt water.

What do brine shrimp eat?

In the wild, brine shrimp feed on algae, cyanobacteria, bits of detritus, archaea, diatoms, and bacteria. In the home aquarium, they will eat any type of flake food or pellet food that is fed to the other inhabitants of the tank.

Brine shrimp also enjoy lettuce, spinach, and cucumber which can be fed sparingly. They should not be overfed as their diet can cause them to produce excess waste that can lead to water quality problems in a freshwater tank.

Tank requirements

If you’re considering a tank, there are some requirements to keep in mind. For example, the tank needs to be at least 10 gallons with a filter. The filter should be rated for at least 10 gallons of water and have an intake tube size of 1/4 inch or greater. The tank should also have a light that is on for 12 to 14 hours per day and provide sufficient oxygenation.

It’s important to note that salt will accumulate over time in the tank and then need to be replaced every 6 months or so. You can buy brackish salt from your local pet store, but it is more cost-effective to make your own brine shrimp mix by boiling about 2 cups of non-iodized table salt in a quart of tap water for 10 minutes until the boiling starts to slow down.

Brine shrimp lifespan

Their average lifespan is about a week to six months.

Brine shrimp breeding

Due to their size, it is almost impossible to distinguish between male and female brine shrimp. As a result of the larger antennae on the male, he utilizes them during coitus to latch onto the female.

Ovulation can occur every 140 hours in a female. Brine shrimp egg hatching can be done almost instantly when the conditions are ideal, which is mind-blowing, producing healthy baby brine shrimp.

It is more likely that the eggs will not hatch if the conditions are extreme, for example, if the salinity is very high or the oxygen level is extremely low. The eggs are coated with chorion when they are laid.

It has been documented that brine shrimp eggs can remain in a stasis-like state under zero oxygen for up to two years. They make an excellent food source for fish farmers, aquarium enthusiasts, and aquarium owners due to their amazing stasis-like state and almost immediate birth of baby brine shrimp.

Do they make good pets?

Some people say that brine shrimp make good pets because they are low maintenance and don’t need a lot of attention. They can also live in small tanks, but they do not interact with their owners as much as other types of pets.
