If the dottyback is aggressive then it won't matter if there is one or more cardinals.That was why I asked about adding a pair of Pajamas instead of one. Is there strength in numbers in a case like this? Also will the Pajamas do better as a pair than a solo act?
Currently the Dottyback is behaving with the 2 Gladiators and the much smaller Blenny so I am hopeful it will work.
PJ cardinals will do equally well singly, as a pr, or as a group.
