u don't have to worry about your anthias gender since they can change the gender according to the group introduced initially...i have 3 dispars and three bule eyes ...actually i bought 8 dispar and 6 blue eyes first then no one eats pallets so with some advise from reefers i started to hatch brine shrimp and feed them then slowly i start to feed them with pallets and brine shrimp together and now its all seems good.but now i have only 3 dispars and 3 blue eyes( all taking pallets only now..very lazy to hatch brine shrimp nowdayz)...waiting for new shipment to buy more of them....good luck..tq
