Yellow Assessor

General information

The Yellow Assessor is a popular saltwater fish among aquarists due to its bright yellow coloration and active behavior. It is a relatively small fish, reaching up to 2 inches in length, and can be kept in a tank of at least 20 gallons. They are peaceful fish and can be kept in groups of three or more.

The Yellow Assessor is an omnivore and feeds on a variety of small crustaceans and zooplankton in the wild. In captivity, they can be fed a varied diet including frozen and live foods such as brine shrimp, krill, and small pieces of fish.

There are no noticeable external differences between male and female Yellow Assessors.

Breeding and spawning in captivity are challenging and have not yet been widely successful. It is recommended to purchase captive-bred individuals to reduce the impact of wild collection.

Yellow Assessors are generally hardy and disease-resistant. However, they can be susceptible to common saltwater fish diseases such as ich and velvet. Proper quarantine and observation before introducing to a display tank can help prevent disease outbreaks.

Yellow Assessors are found in the Western Pacific, specifically in the waters of the Philippines and Indonesia.

Yellow Assessors are generally considered safe to handle, but like many fish, they have a spine on their dorsal fin that can be sharp and cause injury if mishandled. It is important to handle them with care.

Yellow Assessors should be acclimated slowly to their new tank environment over a period of at least an hour to prevent stress and potential shock. A drip acclimation method is recommended.
