The 3 peppermint shrimp in my tank have completely devastated the aptasia population. There is not a single aptasia anenome left (There used to be more of the anenomes then I could count). My concern is this; what are the shrimp going to feed on next? Not my zooanthids or coralimorphs, or my star polyps? Should I seed the tank with more aptasia? Thanks for any advise.
