I recetly added 4 dispar anthias to my tank, they are getting more bold each day and are eating great. There is one certain anthias that when it sees the cleaner shrimp it almost charges for the cleaner shrimp and bump him and then just kind of sits there for about 30 seconds or so then swims off to be with the other 3 anthias. From what i can tell its only one of the 4 anthias doing this. Is it just trying to get cleaned?
