I just added two additional female Square Spot Anthias to an exsisting pair of one male and female. At times two of the females will lip lock and spin in circles and one of the females swims vertically with her tail wiggeling rapidly. Is this behavior normal? Other then that the three females are schooling and generally getting along fine. The male even swims around them more and more but still chases them once in a while. They are all eating well and seem to be settling into their new home. I have had the original pair for 1 month. So far, so good I think? I'm considering adding 3 more in a month or so. Any issues with that? Currently they are in a 125 gallon tank with a pair of Percula clown, 1 cardinal, 1 small blue damsel, 1 cleaner shrimp and a hermit crab. Also considering adding a powder blue tang and a small queen angel down the road. Is that too many fish?
