Hey,
I got a pair of lyrtail anthias ( 1 male, 1 female) I was going to get another female anthias.. but i just got 2 instead. Here is a pic of them.. a bit shy because they are new.
46 is a little small.. But you might get away with bartlett anthias, which get a bit smaller, and are very nice. Brookln Johnny, has some beautiful ones in... i think it is his 65 gallon.
( i might get one more female is i have the space.)
