Assessor macneilli

The Blue Assessor Basslet is also referred to as MacNeill’s Mini Grouper or Macneill’s Assessor Basslet. It is entirely dusky dark blue. This is an excellent choice for reef aquariums.

For a single Blue 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. As a carnivore, the Blue Assessor Basslet will thrive on a diet of meaty foods fed at least twice a day.
