Randall’s Assessor Basslet
The Randall’s Assessor Basslet displays an overall beautiful blue coloration with red accents in its fins as it matures. A dusky purple hue may also be exhibited and compliment this attractive basslet. This is an excellent choice for reef aquariums.
For a single Randall’s Assessor Basslet, provide at least a 30 gallon tank – larger for more individuals and plenty of rock caves for hiding. Due to its aggression and being territorial, it is best to keep only one male Blue Assessor Basslet.
Assessors are known to be shy, cryptic and reclusive when first introduced into the aquarium. In time, a newly introduced Assessor will be seen and enjoyed more frequently with proper aquascaping that offers ample rock to provide nooks and crannies for the fish to dwell in.

The basslet arrived healthy and has been active in my 40-gallon reef tank for three months. It hides in the rock crevices during the day and comes out at night. The blue color with red fins is striking. I’ve added more caves and now it’s more visible. Great addition to my reef.
Adrian Chapman –
First time keeping a basslet. It was a bit shy at first, but after a month of adding more rock structures, it started exploring. The red fin accents are beautiful. I keep only one male, as advised. It’s peaceful when not in its territory.

This basslet has become a highlight in my tank. The coloration is vibrant and it’s not aggressive with other fish. I’ve maintained stable water parameters and it’s thriving. The hiding spots help it feel secure.
