I have a 72x24x21 155 gallon tank with a few wrasse and a juvie pair of A. ocellaris. I also have a Firefish and a Royal Gramma which were the first two fish introduced. Would a Blue Assesor be a problem? Most concerned about the Firefish and Gramma.
Either a blue or gold assessor would work in a six foot tank assuming aquascaping that allows for segregation of territories with the Gramma loretto
