I have 1 male + 3 female bartlett's anthias. Only been a few months so I can't really speak about long term success with them, but so far so good. The thing that is funny is that the other fish in the system tend to come over and they all school together. Well actually I think technically I should say shoal. Never seen any actual schooling. I don't have a ton of fish in my 150, but it's amusing seeing 4 anthias, male and female clarkii, a yellowtail damsel and a bangaii all hanging out in a group like buddies. Although on the downside then there are no fish swimming anywhere else in the tank. Maybe I should get more fish. Hehe.
