I have a blue hippo tang that's about 4.5" now that was raised from about 1.5". Had it in a 90g and now in a 6ft 180g and it has always just swam and stayed in the middle 1/3 of both tanks. Never swims the full length of the tank and never goes into the various caves. When frighten it just darts right into it's usual sleeping hole. The other tangs, Powder Brown, Scopas, and Bristletooth all swim throughout the full tank and enjoy swimming in and out of the caves and arches. Is this normal behavior for hippo tangs since it's commonly said that they swim vast distances in the wild to graze?
