i feed my jack frozen prawns or white bait.. or if i'm keen.. i go catch some live bait as if i go fishing.. and i bring that home for my jack.. he smashes it..
Mine is still in the quaratine tank because it is still too small to put with my other fish. I had it in a reeforium but my Dat and archer kept try to go after it threw the acrylic. So I took him out and put him back in his own tank.
