I do have a pair of Spotcinctus (A. bicinctus). I bought them from Manhattan Aquariums in person (same ownership as
@uniquecorals ).
@Cultivated Reef is a good online source too and Holly is very helpful.
I first added just one Spotcintus to my 45 gallon AIO and later added a smaller as a male. They are not aggressive to other fish, but sometimes the female shoos them away. Never relentlessly. Of course, fish are like people and each has their own personality.
I have Bubble Tip Anemones (one and then a clone split) and they host both clowns. The first Spotcinctus I added took about three days to go in. The male I added later took longer, but was added as a juvenile. As he submitted and grew into his role as a male, he began going into the clone anemone. In time as the Clownfish grew closer, he went freely to both anemones.
