I have a pair of Ocellaris who are intent in hosting my Gonipora. I tried a BTA but it disappeared in my tank, after hiding in the rocks for a while. Then I got a Haddoni that sits all alone at one end of the tank ignored completely by my two clowns (Fred and Wilma). I have a 75 g bowfront and want to add a pair of clowns that will actually host in my haddoni. Is my tank large enough? Any suggestions? Thanks!
