Many say they grow slow but not this fella. Picked him up in May at about 6". Now at 12" . Feeding on Hikari food sticks, pellets, fresh shrimp, beefheart. It was living in my 180, but was getting punked by the Vieja. Currently healing in the 90G. Once the Vieja is sold, it'll be moved back in the 180. Out of my collection, my favorite fishes are this flagtail and my endlie.
