round 1.... i added a regal angel just over a week ago (originally to my fuge) then moved him into the main display tank a few days ago. he seems very happy, is eating, swimming and behaving normal. however, my blue tang (just over twice his size) has taken exception to having the angel in his space. the angel spends most of the time under the reef rack coming out every hour or so for a look around and a feed but as soon as he does, the tang chases him back to his 'hole'. i would expect this to be normal behaviour due to fish being somewhat territorial. are they eventually likely to get along?
