Yellow Assessor

Assessor flavissimus

Yellow Assesors are not a member of the Dottyback family, but are similar to them in many ways. The Yellow Assessor is native to Australia and is a member of the Plesiopidae (Longfins) family which includes the Marine Betta (Comet). They are not nearly as aggressive or territorial as the Dottybacks, and feed on small zooplanktonic crustaceans.

They are fascinating fish that exhibit unusual behaviour. In nature, as well as in the reef tank, they can often be found swimming upside down. This is an adaptation used in their habitat where they’re usually found in caves or under ledges. Creating a similar habitat in the aquarium will allow them to exhibit this unique swimming behaviour.

The Yellow Assessor will not bother invertebrates in the reef aquarium and will accept most frozen and dry prepared foods.
