hes still growing glad i have a large tank for this tank buster . colors seem to be getting darker the red sometimes looks purple . about 18 inches now i didnt measure but just a eyeball guess
yah they can get 3 feet in the wild . yah hes mean as hell and he knows its his tank lol he got my hand once when i tried to rearrange some live rock . luckily he was about 5 inches smaller when he did that . i think he thought my hand was food though . i wish i could put something else in there i envy you guys that have multiple aggresive fish together but just having him in there does make it easy to take care of
