My advise would be you sorta have to decide which direction you want to head with the tank. If you're not willing to give up, even just ever so slightly on the corals, then I'd agree with Nike and say you're already at your max. The present bioload of the tank may not be at the tank's limit, but the future's is significantly higher as everything continues to grow, esp. that Vlamingii, who might only represent one medium-size fish now, but will represent like 4 medium fish and 5 small fish, down the road
.
If you're after a slight compromise tank, where you understand that 'LE Red Pomegranate Acros' may not be at their most vibrant coloration but still do okay, then I'd say you have room for a couple more fish. I think my 90gal reef is similar with a 'healthy' amount of fish.
As far as what fish to add, I think either the Filaments or the Resplendents would fit-in about the same. As mentioned earlier though, the issues with the Filaments issues among themselves could be a problem, but it's not like Anthias are the easiest things on themselves. I would only rate Resplendents mid-pack for Anthias and hardness. They are some of the smaller Anthias, so they don't tolerate harassment very well, I can see some from the tangs, LMB, both angels, and yt damsel. Hawiian Bicolor anthias, Red Striped Anthias, and Redbelted Anthias, are some of the hardier, more unusual Anthias.
