General information

The Blue Assessor, Pseudoplesiops typus, is a small and colorful marine fish that is a member of the family Plesiopidae. It is known for its striking blue coloration and peaceful demeanor, making it a desirable species for reef aquariums. This species is not as commonly available as some other marine ornamentals, but it is prized by enthusiasts for its unique appearance and behavior.

Care

Blue Assessors are relatively hardy and can be a good choice for both novice and experienced aquarists. They require a well-structured aquarium with plenty of hiding places and a stable environment. These fish are not aggressive and can be kept with a variety of other peaceful tank mates. They are carnivorous and should be fed a diet of meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood.

Reproduction

In the wild, Blue Assessors are known to be cave spawners, laying their eggs in protected areas. In the aquarium, breeding is possible but not common. If conditions are right, a pair may spawn, and the male typically guards the eggs until they hatch.

Habitat

Pseudoplesiops typus is found in the Western Pacific, from the Great Barrier Reef to the Solomon Islands. They inhabit coral reefs and are often found in caves or under ledges at depths ranging from 5 to 40 meters. In the aquarium, they appreciate a similar environment with plenty of rockwork and caves to mimic their natural habitat.
