Why not just transfer them into the tank with the aptasia, see if they do their thing then move them back.I like peppermint shrimp- have a couple for over a year- and they might have taken care of any aptasia in that tank- and mine are not nocturnal- all over the tank at feeding time- I just prefer to have different things in all my tanks- one reason why I have 4 instead of one big one
