i want a school of something in my 100 gallon, i think anthias may be what i want to try. any recommendation on what kind? i want something beautiful of course and hardy and more potential to school.
Pseudanthias squamipinnis (lyretail anthias) is pretty widely regarded as the easiest to keep. It's easy to get eating on frozen mysis and Cyclop-eeze and adapts to captivity pretty readily. It should be out and about the day you add it to the tank. Scott Michael did a #reefs talk about Anthias that can be viewed here: http://www.reefs.org/library/talklog/s_ ... 30401.html
Just be aware that what you're forming in your tank is a shoal, not a school. If you're expecting the fish to all swim in the same direction and follow each other like they do in the wild that's probably not what will happen. There will be a lot of aggressive encounters; in addition, the fish tend to hang out and do their own thing in big aquariums.
