The Opae Ula shrimp (Hawaiian red shrimp) are found in freshwater ponds where they eat algae, bacteria and other microbes that naturally form on the substrate. They are considered hardy and live up to 20 years in captivity, and have been successfully raised and kept by hobbyists around the world.

These shrimp are easy to keep and do not require much space or a filter. They can be set up in a variety of tank shapes and sizes, including tall glass vases or jars.

They do not need a heater and will thrive in temperatures of 68-80 degC. If you live in a place where the temperature drops below this range, an aquarium heater is recommended.

You can also keep these shrimp with other tropical fishes, such as angelfish or neon tetras. However, you must consider the size of these creatures, as these can become a problem if they are too big for the shrimp to handle.

It is important to remember that opae ula shrimp have a slow metabolism, and they do not need to be fed often. They eat small amounts of food in a single meal, and you will only need to remove any uneaten food from the tank after it has been consumed by the shrimp.

This will ensure that you do not overfeed these shrimp and pollute the water in your tank. Alternatively, you can feed them blanched vegetables, fish food or shrimp flakes. Source to know about opae ula shrimp.

The diet of opae ula shrimp should be high in calcium and low in carbohydrates. It should also contain a good amount of seaweed or algae, such as Chaetomorpha macro algae or Ulva (sea lettuce).

Opae Ula shrimp can tolerate salinities up to 50%. It is important to only use marine salt when maintaining the salinity of the tank. Generally, you should add about two tablespoons of salt per gallon of dechlorinated water.

A good source of calcium in your shrimp tank will be aragonite sand, which has a lot of carbonate and can be easily added to the tank. It will provide the necessary calcium for your shrimp, and help prevent their skin from drying out and causing irritation.

They are known for their ability to thrive in a wide variety of water conditions, and they can be kept in both a saltwater and brackish tank. They will not breed well if the saltwater or brackish levels are too high or too low, and will also grow very slowly in these types of tanks.

Keeping them with other shrimp is not an issue as opae ula shrimp will not harm or harass other shrimp in the tank. They can be a great addition to the tank of a friend or family member who enjoys keeping shrimp.

Some expert aquarists have successfully paired the opae ula with snails, such as Malaysian Trumpet Snails. These snails can survive in both saltwater and brackish environments, and will eat the biofilm that forms on the surface of the tank.
