Tank Conditions


Saltwater fish need saline water. This could be achieved by mixing salt into the aquarium water. The recommended amount is one half cup of salt per one gallon water. The appropriate salinity for a saltwater fish is 1.024- 1.025. Anything below 1.027 is safe for your tang fish for sale.

Water hardness:

Generally water hardness for tang fish is about 420 ppm. You should test the water hardness levels every week. Acceptable levels in aquariums with reefs are between 380-450ppm.


Bubblers and water filters help necessary oxygen be distributed in tank water. Fish need oxygen in their water to survive. Aquariums with wide tops allow oxygen to also enter from the surface. Oxygen can also be supplied by pumps and air stones, plants, filters used as waterfalls, and less fish in the tank.

Tang Breeding

Pacific Blue Tangs get together in breeding groups at breeding time. The females lay about 40,000 eggs above coral reefs in the wild. The males swim through the eggs and fertilize them. If you want to breed your own tangs, purchasing a pair that has already bonded is recommended.

Algae is the main part of tang diet in the wild. Tangs are omnivores and enjoy mysis and brine shrimp in captivity. Their main diet should be full of plenty of marine algae and unflavored nori. With proper tang care, your tang should be fed once a day. If the tank is small and you only have a few fish, every other day feeding is fine.

Tangs can live for up to thirty years if properly cared for. However, most tangs only reach 25, which is still very old for a fish. Most beginners struggle with proper tang fish care and this is often the cause of a young tang death.
