Blue Assessor Basslet, is entirely dusky dark blue. This is an excellent choice for reef aquariums.
For a single Macneill'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.
