Has anyone experienced an emerald crab being aggressive toward fish? I have seen him eat a six line wrasse, dottyback and now my cardinal fish? I have been feeding them every other day frozen mysis shrimp. Any advice?
Parameters are fine.
The fish are healthy and acting fine. I haven't seen him catch a fish swimming around. I have seen him swipe at the fish. I just got home and see him eating the cardinal. All the fish appear to be very active and healthy
