Lyretail Anthia

[J.R.L.]

i have 1 male lyretail anthia who is doing great, eating well and has a great personality and i would like to add some females

i have a 75g mixed reef with 2 clowns, 1 scopas tang, 1 coral beauty, 1 lyretail anthia (as mentioned above) and 1 yellow coris wrasse...a total of 6 small (less than 2" fish) fish...how many females should i add to get them to possibly school or just plain get along?

Thanks, Josh
