Your experience with anthias is not mine. But, I don't have chromis with them. My anthias (3 Dispar) are model citizens and very active albeit you need to have a regular feeding schedule (at least twice per day) to keep them satiated and healthy. They are among the best and most beautiful group of fish in the tank. They live with a diverse group including: Yellow Belly Blue Tang, Marginalis Butterfly, Regal Angel, Blue Throat Trigger, bonded pair of Red Hawkfish, bonded pair of Snowflake Clownfish, 2 black mollies, 2 striped dartfish, and a blenny. During the day they are generally all out and about except for the dartfish (which tend to hide until feeding) and the Hawkfish which perch and wait.
