Generally, anthias are frequent, mobile feeders in the wild. They prefer small frequent meals, rather than the usual one to two big meals that most people feed their tank. Lyretails are generally pretty hardy and shouldnt have any problem adapting to your tank feeding schedule. Two females generally isnt a problem up front, but more than likely one (or both) will turn into males, and when that happens there can be problems. I have a trio that I keep alongside other anthias (barletts, carberryis and resplendants) and I dont have any issues with feeding. But, I also have enough that the aggression/chasing is spread out amongst all of the fish, and the big male cant bully one female to death.
